Retrieve the RGB value of a pixel within an image
int PiGetPixelRGB( PhImage_t const *image, unsigned short x, unsigned short y, PgColor_t *value );
ph
This function retrieves the RGB value of a pixel within an image.
The image argument is a pointer to a PhImage_t structure that defines the image to be queried, while the x and y arguments specify the coordinates of the pixel to be examined. The value argument points to a PgColor_t where the result of the query is stored.
