Module egui::color

Color conversions and types.

If you want a compact color representation, use Color32. If you want to manipulate RGBA colors use Rgba. If you want to manipulate colors in a way closer to how humans think about colors, use HsvaGamma.

Structs

Color32	This format is used for space-efficient color representation (32 bits).
Hsva	Hue, saturation, value, alpha. All in the range [0, 1]. No premultiplied alpha.
HsvaGamma	Like Hsva but with the v value (brightness) being gamma corrected so that it is somewhat perceptually even.
Rgba	0-1 linear space RGBA color with premultiplied alpha.

Functions

gamma_from_linear	linear [0, 1] -> gamma [0, 1] (not clamped). Works for numbers outside this range (e.g. negative numbers).
gamma_u8_from_linear_f32	linear [0, 1] -> gamma [0, 255] (clamped). Values outside this range will be clamped to the range.
hsv_from_rgb	All ranges in 0-1, rgb is linear.
linear_f32_from_gamma_u8	gamma [0, 255] -> linear [0, 1].
linear_f32_from_linear_u8	linear [0, 255] -> linear [0, 1]. Useful for alpha-channel.
linear_from_gamma	gamma [0, 1] -> linear [0, 1] (not clamped). Works for numbers outside this range (e.g. negative numbers).
linear_u8_from_linear_f32	linear [0, 1] -> linear [0, 255] (clamped). Useful for alpha-channel.
rgb_from_hsv	All ranges in 0-1, rgb is linear.
srgba	Deprecated
tint_color_towards	Cheap and ugly. Made for graying out disabled Ui:s.
