Struct egui::Color32 [−][src]
This format is used for space-efficient color representation (32 bits).
Instead of manipulating this directly it is often better
to first convert it to either Rgba
or Hsva
.
Internally this uses 0-255 gamma space sRGBA
color with premultiplied alpha.
Alpha channel is in linear space.
