Gan_Image * gan_image_extract_q (  const Gan_Image *  source, int  r0, int  c0, unsigned  height, unsigned  width, Gan_ImageFormat  format, Gan_Type  type, Gan_Bool  copy_pixels, Gan_Image *  dest )

Extracts part of an image. Parameters: source  The input image r0  Vertical offset of start of region c0  Horizontal offset of start of region height  Height of region in pixels width  Width of region in pixels format  The format of the output image type  The type of the output image copy_pixels  Whether to copy the pixels from the source image dest  Destination image Returns: Pointer to the extracted/converted image, or NULL on failure. Extracts a sub-part of an image, converting the image to a different format and type if desired. If the copy_pixels flag is set to GAN_TRUE, the pixel data is copied into the destination image; otherwise the destination image is set to point into the source image. See also: gan_image_extract_s().

Gan_Image* gan_image_extract_s (  const Gan_Image *  source, int  r0, int  c0, unsigned  height, unsigned  width, Gan_ImageFormat  format, Gan_Type  type, Gan_Bool  copy_pixels )
