// CuVoodoo Land Pattern files (.cvlp) define the land pattern (aka. footprint) of electronic components (used in printed circuit boards)
|
|
// it is intended to be used in web applications, thus it uses the JSON file format
|
|
// it can then be rendered to various other formats, such as SVG, gEDA pcb, KiCAD, or eagleCAD
|
|
// the coordinate system origin is arbitrary, but the cvlp_lib.js library provided exports uses the 0,0 origin as the top left corner
|
|
// all position and dimensions as float values, except when otherwise specified
