kicad-image-injector
A CLI (Command-line Interface) tool
that allows to inject pixel-based images into
KiCad
PCB
(*.kicad_pcb) files.
When designing a PCB in KiCad, one draws placeholder rectangles on the PCB, in the places and size where one wants the image to appear. Later, one runs this tool with both the KiCad PCB file and a set of image file paths - the same ammount like placeholder rectangles on the PCB - and in turn recieves a KiCad file with the desired images on the PCB.
This is commonly used with the projvar tool,
which supplies a project specific set of such key-value pairs.
