-Gerbolyze high-resolution image-to-PCB converter
-================================================
+Gerbolyze high-fidelity SVG/PNG/JPG to PCB converter
+====================================================
+
+.. note::
+
+    The command-line usage and SVG template format of gerbolyze changed between v2.0 and v3.0. You can find details on
+    the new format below under command_line_usage_
+
+Gerbolyze renders SVG vector and PNG/JPG raster images into existing gerber PCB manufacturing files. 
+Vector data from SVG files is rendered losslessly *without* an intermediate rasterization/revectorization step.
+Still, gerbolyze supports (almost) the full SVG 1.1 spec including complex, self-intersecting paths with holes,
+patterns, dashes and transformations.
+
+Raster images can either be vectorized through contour tracing (like gerbolyze v1.0 did) or they can be embedded using
+high-resolution grayscale emulation while (mostly) guaranteeing trace/space design rules.

 Tooling for PCB art is quite limited in both open source and closed source ecosystems. Something as simple as putting a
 pretty picture on a PCB can be an extremely tedious task. Depending on the PCB tool used, various arcane incantations
 may be necessary and even modestly complex images will slow down most PCB tools to a crawl.
 
-Gerbolyze solves this problem in a toolchain-agnostic way by directly vectorizing bitmap files onto existing gerber
-layers. Gerbolyze has been tested against both the leading open-source KiCAD toolchain and the industry-standard Altium
-Designer. Gerbolyze is written with performance in mind and will happily vectorize tens of thousands of primitives,
-generating tens of megabytes of gerber code without crapping itself. With gerbolyze you can finally be confident that
-your PCB fab's toolchain will fall over before yours does if you overdo it with the high-poly anime silkscreen.

+Tl;dr: Produce high-quality artistic PCBs in three easy steps!
+--------------------------------------------------------------
 
 Gerbolyze works in three steps.
 
-1. Generate a scale-accurate preview of the finished PCB from your CAD tool's gerber output:
+1. Generate a scale-accurate template of the finished PCB from your CAD tool's gerber output:
    
    .. code::
         
-       $ gerbolyze render top my_gerber_dir preview.png
+       $ gerbolyze template --top template_top.svg [--bottom template_bottom.svg] my_gerber_dir
 
-2. Load the resulting preview image into the GIMP or another image editing program. Use it as a guide to position scale
-   your artwork. Create a black-and-white image from your scaled artwork using GIMP's newsprint filter. Make sure most
-   details are larger than about 10px to ensure manufacturing goes smooth.
+2. Load the resulting template image Inkscape_ or another SVG editing program. Put your artwork on the appropriate SVG
+   layer. Dark colors become filled gerber primitives, bright colors become unfilled primitives. You can directly put
+   raster images (PNG/JPG) into this SVG as well, just position and scale them like everything else. SVG clips work for
+   images, too. Masks are not supported.
 
-3. Vectorize the resulting grayscale image drectly into the PCB's gerber files:
+3. Vectorize the edited SVG template image drectly into the PCB's gerber files:

-        $ gerbolyze vectorize top input_gerber_dir output_gerber_dir black_and_white_artwork.png
+        $ gerbolyze paste --top template_top_edited.svg [--bottom ...] my_gerber_dir output_gerber_dir
 
-Image preprocessing guide
--------------------------
+Quick Start Installation (Any Platform)
+---------------------------------------
 
-Nice black-and-white images can be generated from any grayscale image using the GIMP's newsprint filter. The
-straight-forward pre-processing steps necessary for use by ``gerbolyze vectorize`` are as follows.
+.. code-block:: shell
 
-1 Import a render of the board generated using ``gerbolyze render``
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+    python -m pip install --user gerbolyze
 
-``gerbolyze render`` will automatically scale the render such that ten pixels in the render correspond to 6mil on the
-board, which is about the smallest detail most manufacturers can resolve on the silkscreen layer. You can control this
-setting using the ``--fab-resolution`` and ``--oversampling`` options. Refer to ``gerbolyze --help`` for details.
+To uninstall, run

+    python -m pip uninstall gerbolyze gerbonara resvg-wasi svg-flatten-wasi

+
+    python -m pip install --user --upgrade --upgrade-strategy eager gerbolyze
+
+Speeding up gerbolyze using natively-built binaries
+---------------------------------------------------
+
+This will install gerbolyze's binary dependency resvg and gerbolyze's svg-flatten utility as pre-built cross-platform
+WASM binaries. When you first run gerbolyze, it will take some time (~30s) to link these binaries for your system. The
+output is cached, so any future run is going to be fast.
+
+WASM is slower than natively-built binaries. To speed up gerbolyze, you can natively build its two binary dependencies:
+
+1. Install resvg natively using rust's cargo package manager: ``cargo install resvg``
+2. Install gerbolyze's svg-flatten utility natively. You can get pre-built binaries from gerbolyze's gitlab CI jobs `at
+   this link <https://gitlab.com/gerbolyze/gerbolyze/-/pipelines?scope=tags&page=1>`__ by clicking the three dots on the
+   right next to the version you want. These pre-built binaries should work on any x86_64 linux since they are
+   statically linked. You can also build svg-flatten yourself by running ``make`` inside the ``svg-flatten`` folder from
+   a gerbolyze checkout.
+
+Gerbolyze will pick up these binaries when installed in your ``$PATH``. resvg is also picked up when it is installed by
+cargo in your home's ``~/.cargo``, even if it's not in your ``$PATH``. You can override the resvg, usvg or svg-flatten
+binary that gerbolyze uses by giving it the absoulute path to a binary in the ``$RESVG``, ``$USVG`` and ``$SVG_FLATTEN``
+environment variables.
+
+
+Build from source (any distro)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: shell
+
+    git clone --recurse-submodules https://git.jaseg.de/gerbolyze.git
+    cd gerbolyze

+    python3 -m venv

+Features
+--------
+
+Input on the left, output on the right.
+
+.. image:: pics/test_svg_readme_composited.png
+  :width: 800px
+
+* Almost full SVG 1.1 static spec coverage (!)
+
+  * Paths with beziers, self-intersections and holes
+  * Strokes, even with dashes and markers
+  * Pattern fills and strokes
+  * Transformations and nested groups
+  * Proper text rendering with support for complex text layout (e.g. Arabic)
+  * <image> elements via either built-in vectorizer or built-in halftone processor
+  * (some) CSS
+
+* Writes Gerber, SVG or KiCAD S-Expression (``.kicad_mod``) formats
+* Can export from top/bottom SVGs to a whole gerber layer stack at once with filename autodetection
+* Can export SVGs to ``.kicad_mod`` files like svg2mod (but with full SVG support)
+* Beziers flattening with configurable tolerance using actual math!
+* Polygon intersection removal
+* Polygon hole removal (!)
+* Optionally vector-compositing of output: convert black/white/transparent image to black/transparent image
+* Renders SVG templates from input gerbers for accurate and easy scaling and positioning of artwork
+* layer masking with offset (e.g. all silk within 1mm of soldermask)
+* Can read gerbers from zip files
+* Limited SVG support for board outline layers (no fill/region support)
+* Dashed lines supported on board outline layers
+
+Gerbolyze is the end-to-end "paste this svg into these gerbers" command that handles all layers on both board sides at
+once.  The heavy-duty computer geometry logic of gerbolyze is handled by the svg-flatten utility (``svg-flatten``
+directory).  svg-flatten reads an SVG file and renders it into a variety of output formats. svg-flatten can be used like
+a variant of the popular svg2mod that supports all of SVG and handles arbitrary input ``<path>`` elements.
+
+Algorithm Overview
+------------------
+
+This is the algorithm gerbolyze uses to process a stack of gerbers.
+
+* Map input files to semantic layers by their filenames
+* For each layer:
+
+  * load input gerber
+  * Pass mask layers through ``gerbv`` for conversion to SVG
+  * Pass mask layers SVG through ``svg-flatten --dilate``
+  * Pass input SVG through ``svg-flatten --only-groups [layer]`` 
+  * Overlay input gerber, mask and input svg
+  * Write result to output gerber
+
+This is the algorithm svg-flatten uses to process an SVG.
+
+* pass input SVG through usvg_
+* iterate depth-first through resulting SVG.
+
+  * for groups: apply transforms and clip and recurse
+  * for images: Vectorize using selected vectorizer
+  * for paths:
+
+    * flatten path using Cairo
+    * remove self-intersections using Clipper
+    * if stroke is set: process dash, then offset using Clipper
+    * apply pattern fills
+    * clip to clip-path
+    * remove holes using Clipper
+
+* for KiCAD S-Expression export: vector-composite results using CavalierContours: subtract each clear output primitive
+  from all previous dark output primitives
+
+Web interface
+-------------
+
+You can try gerbolyze online at https://dyna.kokoroyukuma.de/gerboweb
+
+The web interface does not expose all of gerbolyze's bells and whistles, but it allows you to simply paste a single SVG
+file on a board to try out gerbolyze. Upload your design on the web interface, then download the template for either the
+top or bottom side, and put your artwork on the appropriate layer of that template using Inkscape_. Finally, upload the
+modified template and let gerbolyze process your design.
+
+Command-line usage
+------------------
+.. _command_line_usage:
+
+Generate SVG template from Gerber files:
+
+.. code-block:: shell
+
+    gerbolyze template [options] [--top|--bottom] input_dir_or.zip output.svg
+
+Render design from an SVG made with the template above into a set of gerber files:
+
+.. code-block:: shell
+
+    gerbolyze paste [options] artwork.svg input_dir_or.zip output_dir_or.zip
+
+Use svg-flatten to convert an SVG file into Gerber or flattened SVG:
+
+.. code-block:: shell
+
+    svg-flatten [options] --format [gerber|svg] [input_file.svg] [output_file]
+
+Use svg-flatten to convert an SVG file into the given layer of a KiCAD S-Expression (``.kicad_mod``) file:
+
+.. code-block:: shell
+
+    svg-flatten [options] --format kicad --sexp-layer F.SilkS --sexp-mod-name My_Module [input_file.svg] [output_file]
+
+Use svg-flatten to convert an SVG file into a ``.kicad_mod`` with SVG layers fed into separate KiCAD layers based on
+their IDs like the popular ``svg2mod`` is doing:
+
+Note:
+    Right now, the input SVG's layers must have *ids* that match up KiCAD's s-exp layer names. Note that when you name
+    a layer in Inkscape that only sets a ``name`` attribute, but does not change the ID. In order to change the ID in
+    Inkscape, you have to use Inkscape's "object properties" context menu function.
+
+    Also note that svg-flatten expects the layer names KiCAD uses in their S-Expression format. These are *different* to
+    the layer names KiCAD exposes in the UI (even though most of them match up!).
+
+    For your convenience, there is an SVG template with all the right layer names and IDs located next to this README.
+
+.. code-block:: shell
+
+    svg-flatten [options] --format kicad --sexp-mod-name My_Module [input_file.svg] [output_file]
+
+``gerbolyze template``
+~~~~~~~~~~~~~~~~~~~~~~
+
+Usage: ``gerbolyze template [OPTIONS] INPUT``
+
+Generate SVG template for gerbolyze paste from gerber files.
+
+INPUT may be a gerber file, directory of gerber files or zip file with gerber files. The output file contains a preview
+image of the input gerbers to allow you to position your artwork, as well as prepared Inkscape layers corresponding to
+each gerber layer. Simply place your artwork in this SVG template using Inkscape. Starting in v3.0, gerbolyze
+automatically keeps track of which board side (top or bottom) is contained in an SVG template.
+
+Options:
+********
+``--top | --bottom``
+    Output top or bottom side template. This affects both the preview image and the prepared Inkscape layers.
+
+``--vector | --raster``
+    Embed preview renders into output file as SVG vector graphics instead of rendering them to PNG bitmaps. The
+    resulting preview may slow down your SVG editor.
+
+``--raster-dpi FLOAT``
+    DPI for rastering preview
+
+``--bbox TEXT``
+    Output file bounding box. Format: "w,h" to force [w] mm by [h] mm output canvas OR "x,y,w,h" to force [w] mm by [h]
+    mm output canvas with its bottom left corner at the given input gerber coördinates.
+
+
+``gerbolyze paste``
+~~~~~~~~~~~~~~~~~~~
+(see `below <vectorization_>`__)
+
+Usage: ``gerbolyze paste [OPTIONS] INPUT_GERBERS OVERLAY_SVG OUTPUT_GERBERS``
+
+Render vector data and raster images from SVG file into gerbers. The SVG input file can be generated using ``gerbolyze
+template`` and contains the name and board side of each layer. Note that for board outline layers, handling slightly
+differs from other layers as PCB fabs do not support filled Gerber regions on these layers.
+
+Options:
+********
+
+``--bbox TEXT``
+    Output file bounding box. Format: "w,h" to force [w] mm by [h] mm output canvas OR "x,y,w,h" to force [w] mm by [h]
+    mm output canvas with its bottom left corner at the given input gerber coördinates. This **must match the ``--bbox`` value given to
+    template**!
+
+``--subtract TEXT``
+    Use user subtraction script from argument (see `below <subtraction_script_>`_)
+
+``--no-subtract``
+    Disable subtraction (see `below <subtraction_script_>`_)
+
+``--dilate FLOAT``
+    Default dilation for subtraction operations in mm (see `below <subtraction_script_>`_)
+
+``--trace-space FLOAT``
+    Passed through to svg-flatten, see `below <svg_flatten_>`__.
+
+``--vectorizer TEXT``
+    Passed through to svg-flatten, see `its description below <svg_flatten_>`__. Also have a look at `the examples below <vectorization_>`_.
+
+``--vectorizer-map TEXT``
+    Passed through to svg-flatten, see `below <svg_flatten_>`__.

+Outline layers
+**************
+
+Outline layers require special handling since PCB fabs do not support filled G36/G37 polygons on these layers. The main
+difference between normal layers and outline layers is how strokes are handled. On outline layers, strokes are
+translated to normal Gerber draw commands (D01, D02 etc.) with an aperture set to the stroke's width instead of tracing
+them to G36/G37 filled regions. This means that on outline layers, SVG end caps and line join types do not work: All
+lines are redered with round joins and end caps.
+
+One exception from this are patterns, which work as expected for both fills and strokes with full support for joins and
+end caps.
+
+Dashed strokes are supported on outline layers and can be used to make easy mouse bites.

+
+Subtraction scripts
+*******************
+
+.. image:: pics/subtract_example.png
+  :width: 800px
+
+Subtraction scripts tell ``gerbolyze paste`` to remove an area around certain input layers to from an overlay layer.
+When a input layer is given in the subtraction script, gerbolyze will dilate (extend outwards) everything on this input
+layer and remove it from the target overlay layer. By default, Gerbolyze subtracts the mask layer from the silk layer to
+make sure there are no silk primitives that overlap bare copper, and subtracts each input layer from its corresponding
+overlay to make sure the two do not overlap. In the picture above you can see both at work: The overlay contains
+halftone primitives all over the place. The subtraction script has cut out an area around all pads (mask layer) and all
+existing silkscreen. You can turn off this behavior by passing ``--no-subtract`` or pass your own "script".
+
+The syntax of these scripts is:
+
+.. code-block::
+
+    {target layer} -= {source layer} {dilation} [; ...]
+
+The target layer must be ``out.{layer name}`` and the source layer ``in.{layer name}``. The layer names are gerbolyze's
+internal layer names, i.e.: ``paste, silk, mask, copper, outline, drill``
+
+The dilation value is optional, but can be a float with a leading ``+`` or ``-``. If given, before subtraction the
+source layer's features will be extended by that many mm. If not given, the dilation defaults to the value given by
+``--dilate`` if given or 0.1 mm otherwise. To disable dilation, simply pass ``+0`` here.
+
+Multiple commands can be separated by semicolons ``;`` or line breaks.
+
+The default subtraction script is:
+
+.. code-block::
+
+    out.silk -= in.mask
+    out.silk -= in.silk+0.5
+    out.mask -= in.mask+0.5
+    out.copper -= in.copper+0.5
+
+.. _svg_flatten:
+
+``svg-flatten``
+~~~~~~~~~~~~~~~
+
+Usage: ``svg-flatten [OPTIONS]... [INPUT_FILE] [OUTPUT_FILE]``
+
+Specify ``-`` for stdin/stdout.
+
+Options:
+********
+
+``-h, --help``
+    Print help and exit
+
+``-v, --version``
+    Print version and exit
+
+``-o, --format``
+    Output format. Supported: gerber, gerber-outline (for board outline layers), svg, s-exp (KiCAD S-Expression)
+
+``-p, --precision``
+    Number of decimal places use for exported coordinates (gerber: 1-9, SVG: >=0). Note that not all gerber viewers are
+    happy with too many digits. 5 or 6 is a reasonable choice.
+
+``--clear-color``
+    SVG color to use in SVG output for "clear" areas (default: white)
+
+``--dark-color``
+    SVG color to use in SVG output for "dark" areas (default: black)
+
+``-f, --flip-gerber-polarity``
+    Flip polarity of all output gerber primitives for --format gerber.
+
+``-d, --trace-space``
+    Minimum feature size of elements in vectorized graphics (trace/space) in mm. Default: 0.1mm.
+
+``--no-header``
+    Do not export output format header/footer, only export the primitives themselves
+
+``--flatten``
+    Flatten output so it only consists of non-overlapping white polygons. This perform composition at the vector level.
+    Potentially slow. This defaults to on when using KiCAD S-Exp export because KiCAD does not know polarity or colors.
+
+``--no-flatten``
+    Disable automatic flattening for KiCAD S-Exp export

+    Map from image element id to vectorizer. Overrides --vectorizer.  Format: id1=vectorizer,id2=vectorizer,...
+
+    You can use this to set a certain vectorizer for specific images, e.g. if you want to use both halftone
+    vectorization and contour tracing in the same SVG. Note that you can set an ``<image>`` element's SVG ID from within

+
+``--sexp-layer``
+    Layer for KiCAD S-Exp output. Defaults to auto-detect layers from SVG layer/top-level group IDs. If given, SVG
+    groups and layers are completely ignored and everything is simply vectorized into this layer, though you cna still
+    use ``-g`` for group selection.
+

+
+``--usvg-dpi``
+    Passed through to usvg's --dpi, in case the input file has different ideas of DPI than usvg has.
+
+``--scale``
+    Scale input svg lengths by this factor (-o gerber only).
+
+``-e, --exclude-groups``
+    Comma-separated list of group IDs to exclude from export. Takes precedence over --only-groups.
+
+.. _vectorization:
+
+Gerbolyze image vectorization
+-----------------------------
+
+Gerbolyze has two built-in strategies to translate pixel images into vector images. One is its built-in halftone
+processor that tries to approximate grayscale. The other is its built-in binary vectorizer that traces contours in
+black-and-white images. Below are examples for the four options.
+
+The vectorizers can be used in isolation through ``svg-flatten`` with either an SVG input that contains an image or a
+PNG/JPG input.
+
+The vectorizer can be controlled globally using the ``--vectorizer`` flag in both ``gerbolyze`` and ``svg-flatten``. It
+can also be set on a per-image basis in both using ``--vectorizer-map [image svg id]=[option]["," ...]``.
+
+.. for f in vec_*.png; convert -background white -gravity center $f -resize 500x500 -extent 500x500 (basename -s .png $f)-square.png; end

+The binary contours vectorizer requires a black-and-white binary input image. As you can see, like every bitmap tracer
+it will produce some artifacts. For artistic input this is usually not too bad as long as the input data is
+high-resolution. Antialiased edges in the input image are not only OK, they may even help with an accurate
+vectorization.

+GIMP halftone preprocessing guide
+---------------------------------
+
+Gerbolyze has its own built-in halftone processor, but you can also use the high-quality "newsprint" filter built into
+GIMP_ instead if you like. This section will guide you through this. The PNG you get out of this can then be fed into
+gerbolyze using ``--vectorizer binary-contours``.

+Manufacturing Considerations
+----------------------------
+
+The main consideration when designing artwork for PCB processes is the processes' trace/space design rule. The two
+things you can do here is one, to be creative with graphical parts of the design and avoid extremely narrow lines,
+wedges or other thin features that will not come out well. Number two is to keep detail in raster images several times
+larger than the manufacturing processes native capability. For example, to target a trace/space design rule of 100 µm,
+the smallest detail in embedded raster graphics should not be much below 1mm.
+
+Gerbolyze's halftone vectorizers have built-in support for trace/space design rules. While they can still produce small
+artifacts that violate these rules, their output should be close enough to satifsy board houses and close enough for the
+result to look good. The way gerbolyze does this is to clip the halftone cell's values to zero whenevery they get too
+small, and to forcefully split or merge two neighboring cells when they get too close. While this process introduces
+slight steps at the top and bottom of grayscale response, for most inputs these are not noticeable.
+
+On the other hand, for SVG vector elements as well as for traced raster images, Gerbolyze cannot help with these design
+rules. There is no heuristic that would allow Gerbolyze to non-destructively "fix" a design here, so all that's on the
+roadmap here is to eventually include a gerber-level design rule checker.
+
+As far as board houses go, I have made good experiences with the popular Chinese board houses. In my experience, JLC
+will just produce whatever you send them with little fucks being given about design rule adherence or validity of the
+input gerbers. This is great if you just want artistic circuit boards without much of a hassle, and you don't care if
+they come out exactly as you imagined. The worst I've had happen was when an older version of gerbolyze generated
+polygons with holes assuming standard fill-rule processing. The in the board house's online gerber viewer things looked
+fine, and neither did they complain during file review. However, the resulting boards looked completely wrong because
+all the dark halftones were missing.
+
+PCBWay on the other hand has a much more rigurous file review process. They <em>will</em> complain when you throw
+illegal garbage gerbers at them, and they will helpfully guide you through your design rule violations. In this way you
+get much more of a professional service from them and for designs that have to be functional their higher level of
+scrutiny definitely is a good thing. For the design you saw in the first picture in this article, I ended up begging
+them to just plot my files if it doesn't physically break their machines and to their credit, while they seemed unhappy
+about it they did it and the result looks absolutely stunning.
+
+PCBWay is a bit more expensive on their lowest-end offering than JLC, but I found that for anything else (large boards,
+multi-layer, gold plating etc.) their prices match. PCBWay offers a much broader range of manufacturing options such as
+flexible circuit boards, multi-layer boards, thick or thin substrates and high-temperature substrates.
+
+When in doubt about how your design is going to come out on the board, do not hesitate to contact your board house. Most
+of the end customer-facing online PCB services have a number of different factories that do a number of different
+fabrication processes for them depending on order parameters. Places like PCBWay have exceptional quality control and
+good customer service, but that is mostly focused on the technical aspects of the PCB. If you rely on visual aspects
+like silkscreen uniformity or solder mask color that is a strong no concern to everyone else in the electronics
+industry, you may find significant variations between manufacturers or even between orders with the same manufacturer
+and you may encounter challenges communicating your requirements.
+
+Limitations
+-----------
+
+SVG raster features
+~~~~~~~~~~~~~~~~~~~
+
+Currently, SVG masks and filters are not supported. Though SVG is marketed as a "vector graphics format", these two
+features are really raster primitives that all SVG viewers perform at the pixel level after rasterization. Since
+supporting these would likely not end up looking like what you want, it is not a planned feature. If you need masks or
+filters, simply export the relevant parts of the SVG as a PNG then include that in your template.
+
+Gerber pass-through
+~~~~~~~~~~~~~~~~~~~
+
+Since gerbolyze has to composite your input gerbers with its own output, it has to fully parse and re-serialize them.
+gerbolyze gerbonara_ for all its gerber parsing needs. Thus, gerbonara will interpret your gerbers and output will be in
+gerbonara's gerber "dialect". If you find a corner case where this does not work and the output looks wrong, please file
+a bug report with an example file on the gerbonara_ bug tracker. *Always* check the output files for errors before
+submitting them to production.
+
+Gerbolyze is provided without any warranty, but still please open an issue or `send me an email
+<mailto:gerbolyze@jaseg.de>`__ if you find any errors or inconsistencies. 
+
+Trace/Space design rule adherence
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+While the grayscale halftone vectorizers do a reasonable job adhering to a given trace/space design rule, they can still
+produce small parts of output that violate it. For the contour vectorizer as well as for all SVG primitives, you are
+responsible for adhering to design rules yourself as there is no algorithm that gerboyze could use to "fix" its input.
+
+A design rule checker is planned as a future addition to gerbolyze, but is not yet part of it. If in doubt, talk to your
+fab and consider doing a test run of your design before ordering assembled boards ;)

+      Gerbolyze is a tool for rendering arbitrary vector (SVG) and raster (PNG/JPG) images directly onto gerber layers.
+      You can use this to put art on a PCB's silkscreen, solder mask or copper layers. The input is an SVG file
+      generated from a template. This SVG file has one layer for each PCB layer and the layers are rendered one by one
+      into the existing gerber file. SVG primitives are converted as-is with (almost) full SVG support, and bitmap
+      images are vectorized using a vector halftone processor. Gerbolyze works with gerber files produced with any EDA
+      toolchain and has been tested to work with both Altium and KiCAD.
