        LPVOID lpReserved
);

Arguments:

Name Type Description
hIGear HIGEAR HIGEAR handle of image, or NULL.

lpOption LPVOID A long pointer to VOID data returned as display option data.
lpReserved LPVOID This argument is reserved for future use. Please set to NULL for now.

Return Value:

Supported Raster Image Formats:

This function does not process image pixels.

Remarks:

The value that you set for hIGear determines whether the option settings will be retrieved from a specific image or a global setting for all new HIGEAR images. If you set hIGear to a specific image, the settings for that image will be returned. If you set hIGear to NULL, global settings for all new HIGEAR images will be returned.

See the description under IG_display_option_set() for more details about the display settings.
