Remove svgwrite backend
2015-11-15Remove svgwrite backendPaulo Henrique Silva5-137/+4
We moved the functionality to cairo backend, it can write png and svg and maybe more (pdfs?)

2015-11-13Merge pull request #43 from curtacircuitos/excellon-with-no-tool-definitionHamilton Kibbe1-1/+18
Add fix to work with excellon with no tool definition.
2015-11-13Add fix to work with excellon with no tool definition.Paulo Henrique Silva1-1/+18
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.
2015-11-13Fix issue when a region is created as the first graphical object in a filePaulo Henrique Silva1-2/+5
When regions were the first thing draw there is no current aperture defined, as regions do not require an aperture, so we use an zeroed Circle as aperture in this case. Gerber spec says that apertures have no graphical meaning for regions, so this should be enough.

Improve Excellon parsing coverage
2015-11-13Improve Excellon parsing coveragePaulo Henrique Silva3-16/+226
Add some not so used codes that were generating unknown stmt.

Read from memory
2015-10-10Python 3 fixHamilton Kibbe2-2/+10
2015-10-10Allow files to be read from strings per #37Hamilton Kibbe10-53/+140
Adds a loads() method to the top level module which generates a GerberFile or ExcellonFile from a string

Cairo render unification
2015-08-09Add support for arcs in regions.Hamilton Kibbe4-49/+70
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.
2015-07-25Fix windows permission errorHamilton Kibbe1-1/+3
per #33 the issue was trying to re-open the temporary file. it works on everything but windows. I've changed it to seek to the beginning and read from the file without re-opening, which should fix the issue.
2015-07-22Fix multiple layer issue in cairo-unification branch (see #33)Hamilton Kibbe3-11/+14
2015-07-14Merge pull request #31 from curtacircuitos/statement_linkPaulo Henrique Silva9-83/+647
Add support for tool reordering and drill path optimization example.
2015-07-09Fix arcs and ackground paintingPaulo Henrique Silva2-2/+8
2015-07-09Initial patch to unify our render towards cairoPaulo Henrique Silva3-39/+62
This branch allows a pure cairo based render for both PNG and SVG. Cairo backend is mostly the same but with improved support for configurable scale, orientation and inverted color drawing. API is not yet final.
2015-07-06Add tool path optimization exampleHamilton Kibbe5-10/+469
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

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

2015-05-21G70/G71 are now interpreted as MOParamStmt.Paulo Henrique Silva1-2/+4
Got a bunch of metric files with no MOMM but only G71, this should be pretty mush harmless.
2015-05-21Fix multiline read of mixed statements (%XXX*% followed by DNN*)Paulo Henrique Silva3-1/+20
We now check if there is a %XXX*% command inside the line before considering it a multiline statement.
2015-05-21Fix ADD statement parsing for concatened statements.Paulo Henrique Silva2-3464/+7
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.
2015-05-20Add support for PCBmodE generated files.Paulo Henrique Silva2-1/+19
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.
2015-05-16Add checks to ensure statement unit conversions are idempotentHamilton Kibbe6-89/+379
2015-04-27Allow 3 digits on Excellon tool selectionPaulo Henrique Silva2-2/+10
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)

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
