This example demonstrates the use of pcb-tools with cairo to render a composite
|
|
image from a set of gerber files. Each layer is loaded and drawn using a
|
|
GerberCairoContext. The color and opacity of each layer can be set individually.
|
|
Once all thedesired layers are drawn on the context, the context is written to
|
|
a .png file.
