KiBot/kibot/PcbDraw

PcbDraw code

Why?

• Important dependency: PcbDraw is currently a core functionality of KiBot because its used for the pcb_print output
• Increased number of dependencies: The upstream code pulls too much dependencies, some of them optional, others that we don't need. This is a constant problem.
• Incompatible interface and behavior: This should be fixed now that 1.0.0 is out, but I don't agree with the idea of doing small changes just because they look more elegant.
• Now integrable: This is one of the changes in 1.0.0, now the code is easier to call as module.
• Repeated functionality: The render stuff is already implemented by KiAuto.

Details

Currently only the plot module is included.

plot.py

• Made the pcbdraw import relative
• Disabled shrink_svg
  • Changes the old behavior, so this should be optional
  • Pulls a problematic dependency: svgpathtool
• Changed calls to ComputeBoundingBox() to use aBoardEdgesOnly=True
  • To get the same behavior as 0.9.0-5
  • This changes the size of the SVG to the size of the board
  • shrink_svg must be disabled or it reverts the size to the detected
• Added no_warn_back option to disable warnings on the opposite side
