Convert alpha, red, green, and blue values to composite color format
PgColor_t PgARGB( int A,
int R,
int G,
int B );
- A
- The alpha value.
- R
- The red value.
- G
- The green value.
- B
- The blue value.
ph
This macro converts alpha, red, green, and blue values into a
composite color value (of type
PgColor_t).
The values for alpha, red, green, and blue range from 0 to 255.
If you set the red, green, and blue values to 0, the color is
black; if you set them to 255, the color is white.
The meaning of the alpha value depends on the alpha model that you're using.
|
This macro doesn't check the color model currently in use, and gives
undefined results if you're not using the Pg_CM_ARGB model. |
