Flags

Options

GFL_LOAD_SKIP_ALPHA	If the picture has an alpha channel, it is ignored
GFL_LOAD_IGNORE_READ_ERROR	Ignore all read errors
GFL_LOAD_BY_EXTENSION_ONLY	Use only extension to recognize the filetype
GFL_LOAD_READ_ALL_COMMENT	Read all comment in the file
GFL_LOAD_FORCE_COLOR_MODEL	ColorModel is used for the picture type
GFL_LOAD_PREVIEW_NO_CANVAS_RESIZE	Keep the ratio for the preview
GFL_LOAD_BINARY_AS_GREY	Load a binary file in 8bits
GFL_LOAD_ORIGINAL_COLORMODEL	If the color model of the file is CMYK, so the picture loaded will be in CMYK
GFL_LOAD_ONLY_FIRST_FRAME	If the color model of the file is CMYK, so the picture loaded will be in CMYK
GFL_LOAD_ORIGINAL_DEPTH	If the file has more than 8 bits per component, keep it
