Remarks:
 |
ImageGear currently uses only two types of image storage (compression): "Run Ends" and "Standard". ImageGear always uses "Run Ends" compression for 1-bit images, and "Standard" (uncompressed) format for all other types of images. If the function returns any value other than IG_BI_RLE and IG_BI_EMPTY, this means that the DIB uses Standard storage format. This behavior is preserved for compatibility with previous versions of ImageGear. |
