Detailed Description

Low level drawing API Drawing Functions.

Coordinates and distances are ALWAYS in PCB's default coordinates (1 nm at the time this comment was written).

Angles are always in degrees, with 0 being "right" (positive X) and 90 being "up" (positive Y).

hidGC(* hid_draw_st::make_gc)(void)

Make an empty graphics context.

void(* hid_draw_st::set_color)(hidGC gc, const char *name)

Set a color. Names can be like "red" or "#rrggbb" or special names like "erase". *Always* use the "erase" color for removing ink (like polygon reliefs or thermals), as you cannot rely on knowing the background color or special needs of the HID. Always use the "drill" color to draw holes. You may assume this is cheap enough to call inside the redraw callback, but not cheap enough to call for each item drawn.

void(* hid_draw_st::set_draw_faded)(hidGC gc, int faded)

Blends 20% or so color with 80% background. Only used for assembly drawings so far.

void(* hid_draw_st::set_line_cap)(hidGC gc, EndCapStyle style)

Set the line style. While calling this is cheap, calling it with different values each time may be expensive, so grouping items by line style is helpful.
