2016-11-07cairo_backend.py: use BytesIO instead of StringIOGirts Folkmanis1-6/+3
This fixes a crash in cairocffi on Python3, and should be compatible with both python2 and python3. In python2, byte strings are just strings. In python3, when getting binary data, the user probably wants a byte string instead of a regular string.
2016-01-28Cleanup, rendering fixes.Hamilton Kibbe1-82/+90
fixed rendering of tented vias fixed rendering of semi-transparent layers fixed file type detection issues added some examples
2016-01-21Add support for mirrored renderingHamilton Kibbe1-7/+12
- The default theme now renders the bottom layers mirrored. - see https://github.com/curtacircuitos/pcb-tools/blob/master/examples/pcb_bottom.png for an example.
2016-01-21Fix a bunch of rendering bugs.Hamilton Kibbe1-114/+141
- '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
2016-01-01Refactor a littleHamilton Kibbe1-45/+51
pulled all rendering stuff out of the pcb/layer objects
2015-12-22Python3 fixHamilton Kibbe1-2/+2
2015-12-22Add PCB interfaceHamilton Kibbe1-15/+47
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
2015-12-20Allow renderer to write to memory per #38Hamilton Kibbe1-3/+16
Some updates to rendering colors/themes
2015-12-20Clean up negative render codeHamilton Kibbe1-76/+69
2015-12-19Allow negative render of soldermask per #50Hamilton Kibbe1-37/+84
Update example code and rendering to show change
2015-10-10Allow files to be read from strings per #37Hamilton Kibbe1-0/+6
Adds a loads() method to the top level module which generates a GerberFile or ExcellonFile from a string
2015-08-09Add support for arcs in regions.Hamilton Kibbe1-5/+17
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 Kibbe1-10/+13
2015-07-09Fix arcs and ackground paintingPaulo Henrique Silva1-1/+5
2015-07-09Initial patch to unify our render towards cairoPaulo Henrique Silva1-37/+50
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.

2015-02-15Add cairo example code, and use example-generated image in readmeHamilton Kibbe1-5/+7
2015-02-13Fix rendering for line with rectangular aperture per #12. Still need to do ↵Hamilton Kibbe1-4/+9
the same for arcs.
2015-02-12Update line primitive to take aperture parameterHamilton Kibbe1-7/+13
This fixes the exception referenced in #12. Still need to add rendering code for rectangle aperture lines and arcs. Rectangle strokes will be drawn as polygons by the rendering backends.
