b9f1b106c3 Excellon format detection uses ExcelonFile.bounds now 
Long term we should have only one .bounds method. But ExcellonParser right
now is not correct for cases with two drills in the same line
(it will report one dimension being zero)

5476da8aa3 Fix a bunch of rendering bugs. 
- 'clear' polarity primitives no longer erase background
  - Added aperture macro support for polygons
  - Added aperture macro rendring support
  - Renderer now creates a new surface for each layer and merges them instead of working
    directly on a single surface
  - Updated examples accordingly

cead702f4d Add fix to work with excellon with no tool definition. 
I found out that Proteus generate some strange Excellon without any tool definition.
Gerbv renders it correctly and after digging in I found the heuristic that they use
to "guess" the tool diameter. This change replicates this behavior on pcb-tools.

dd63b169f1 Allow files to be read from strings per #37

15254a5bb7 Add tool path optimization example 
Add example demonstrating use of tsp-solver with pcb-tools to optimize
tool paths in an excellon file. This is based on @koppi's script in #30

94f3976915 Add keys to statements for linking to primitives. Add some API features to ExcellonFile, such as getting a tool path length and changing tool parameters. Excellonfiles write method generates statements based on the drill hits in the hits member, so drill hits in a generated file can be re-ordered by re-ordering the drill hits in ExcellonFile.hits. see #30 2015-06-11 11:20:56 -04:00

390838fc8b Fix for #25. Checking was happening at the gerber/excellon file level, but I added units checking at the primitive level so the use case shown in the example is covered. Might want to throw a bunch more assertions in the test code (i started doing a few) to cover multiple calls to unit conversion functions 2015-04-24 10:54:13 -04:00

0f36084aad Add Repeat Hole Stmt and fix UnitStmt parsing 
* Repeat hole support (with no real parsing, just a copy)
* Fix UnitStmt to works even when a ,TZ or ,LZ information is not provided.

137c73f3e4 Many additions to Excellon parsing/creation. 
CAUTION: the original code used zero_suppression flags
         in the opposite sense as Gerber functions. This
         patch changes it to behave just like Gerber code.

* Add metric/inch conversion support
* Add settings context variable to to_gerber just like Gerber code.
* Add some missing Excellon values.

Tests are not entirely updated.
