Gan_Image* gan_image_composite_i (  Gan_Image *  image, const Gan_Image *  source_with_alpha, const Gan_Image *  source_mask )

Macro: Composite with overwriting. Parameters: image  The input/output image source_with_alpha  The input image with the alpha channel source_mask  Binary mask for source image or NULL Returns: Composited image, or NULL on failure. Composites the image source_with_alpha onto the given image, overwriting the result onto image. If source_mask is not NULL, only pixels in the mask are composited. See also: gan_image_composite_q().

Gan_Image * gan_image_composite_q (  Gan_Image *  source, const Gan_Image *  source_with_alpha, const Gan_Image *  source_mask, Gan_Image *  dest )

Macro: Composite images. Parameters: source  The input image source_with_alpha  The input image with the alpha channel source_mask  Binary mask for source image or NULL dest  The destination image Returns: Composited dest image, or NULL on failure. Composites the image source_with_alpha onto the given image source, writing the result onto dest. See also: gan_image_composite_i().

Gan_Image* gan_image_composite_s (  Gan_Image *  image, const Gan_Image *  source_with_alpha, const Gan_Image *  source_mask )

Macro: Composite into a new image. Parameters: image  The input image source_with_alpha  The input image with the alpha channel source_mask  Binary mask for source image or NULL Returns: Composited output image, or NULL on failure. Composites the image source_with_alpha onto the given image, overwriting the result onto image. If source_mask is not NULL, only pixels in the mask are composited. See also: gan_image_composite_q().
