PgARGB()

Convert alpha, red, green, and blue values to composite color format

Synopsis:

PgColor_t PgARGB( int A,
                  int R,
                  int G,
                  int B );

Arguments:

A

The alpha value.

R

The red value.

G

B

The blue value.

Library:

Description:

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.
