The ilOriginFunc sets the default origin to be used when loading images.

Mode

An enum specifying the origin to be used. Accepted values are:

IL_ORIGIN_LOWER_LEFT

The origin is in the lower left of the image.

IL_ORIGIN_UPPER_LEFT

The origin is in the upper left of the image.

ilOriginFunc sets the origin to be used when loading all images, so that any image with a different origin will be flipped to have the set origin. This behaviour is actually disabled by default but can be enabled using ilEnable with the IL_ORIGIN_SET parameter.

IL_INVALID_PARAM - Mode was of an invalid value.
