ImageGear provides two ways to access image attributes: via the HIGEAR handle, and via the special object HIGDIBINFO, which encapsulates the image attributes.

The HIGDIBINFO object only contains the attributes and does not contain the pixels.

Use IG_DIB_info_create to create a DIB info object. Use IG_DIB_info_copy to create a copy of an existing object. Use IG_image_DIB_info_get to obtain DIB information from a HIGEAR handle.

When the HIGDIBINFO object is no longer in use, you must delete it using IG_DIB_info_delete.

You cannot edit the DIB information of a HIGEAR directly. Instead, use image processing functions to modify the image: resize, convert to a different color space, change its resolution, etc.
