Color¶

Functions

sfColor sfColor_fromRGB(uint8_t red, uint8_t green, uint8_t blue)¶

Construct a color from its 3 RGB components.

Parameters:

red – Red component (0 .. 255)
green – Green component (0 .. 255)
blue – Blue component (0 .. 255)

Returns:

sfColor constructed from the components

sfColor sfColor_fromRGBA(uint8_t red, uint8_t green, uint8_t blue, uint8_t alpha)¶

Construct a color from its 4 RGBA components.

Parameters:

red – Red component (0 .. 255)
green – Green component (0 .. 255)
blue – Blue component (0 .. 255)
alpha – Alpha component (0 .. 255)

Returns:

sfColor constructed from the components

sfColor sfColor_fromInteger(uint32_t color)¶

Construct the color from 32-bit unsigned integer.

Parameters:

color – Number containing the RGBA components (in that order)

Returns:

sfColor constructed from the 32-bit unsigned integer

uint32_t sfColor_toInteger(sfColor color)¶

Convert a color to a 32-bit unsigned integer.

Returns:: Color represented as a 32-bit unsigned integer

sfColor sfColor_add(sfColor color1, sfColor color2)¶

Parameters:

color1 – First color
color2 – Second color

Returns:

Component-wise saturated addition of the two colors

sfColor sfColor_subtract(sfColor color1, sfColor color2)¶

sfColor sfColor_modulate(sfColor color1, sfColor color2)¶

Modulate two colors.

Parameters:

color1 – First color
color2 – Second color

Returns:

Component-wise multiplication of the two colors
