Convert alpha, red, green, and blue values to composite color format
PgColor_t PgARGB( int A, int R, int G, int B );
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. |
