965d3ce23b Add more tests for rendering to PNG. Start adding tests for rendering to Gerber format. Changed definition of no hole to use None instead of 0 so we can differentiate when writing to Gerber format. Makde polygon use hole diameter instead of hole radius to match other primitives 2016-07-24 22:08:31 +08:00

49dadd46ee Fix AMParamStmt to_gerber to write changes back. 
AMParamStmt was not calling to_gerber on each of its primitives
on his own to_gerber method. That way primitives that changes after reading,
such as when you call to_inch/to_metric was failing because it was
writing only the original macro back.

6f876edd09 Add PCB interface 
this incorporates some of @chintal's layers.py changes
PCB.from_directory() simplifies loading of multiple gerbers
the PCB() class should be pretty helpful going forward...

the context classes could use some cleaning up, although I'd like to wait until the freecad stuff gets merged, that way we can try to refactor the context base to support more use cases

cb2fa34e88 Add support for arcs in regions. 
This fixes the circular cutout issue described in #32.  Regions were previously stored as a collection of points, now they are stored as a collection of line and arc primitives.

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

aff36a4dca Fix multiline read of mixed statements (%XXX*% followed by DNN*) 
We now check if there is a %XXX*% command inside the line before
considering it a multiline statement.

2fe5f36db2 Fix ADD statement parsing for concatened statements. 
ADDxxx param statements were too greedy on the mofidiers and were
matching more than it should in cases where there are no newlines after
the statement like:

'%ADD12C,0.305*%%LPD*%', in a single line. The '%' was not exluded form
modifiers so it got confused with the %LPD*% concatened.

top_copper.GTL example was changed to be in a single line now with no
spaces at all and it works well.

d3b19efb48 Add support for PCBmodE generated files. 
PCBmodE uses a standard but probably undefined behaviour issue
on Gerber where it defines circle apertures with a single modifier
but leaves a trilling 'X' after it. 'X' is modifiers separator but
when there is only one modifier the behaviour is undefined.

For parsing we are just ignoring blank modifiers.

Test updated to catch this case.

21d963d244 Allow 3 digits on Excellon tool selection 
Fritzing uses more than 2 digits for tool in their Excellons. To comply
with that, I check specifically for 3 or less digits and use as tool
number, more than that we treat as the standard (2 for tool and 2 for
compensation index)

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
