API Reference Guide > Core Component API Reference > Core Component Structures Reference > AT_RESOLUTION

This struct describes an image's resolution. This information is used to map between a number of pixels and a physical length measurement. For example, if you have an image that is 600 pixels wide, and the horizontal resolution is specified as 300 DPI (dots per inch, IG_RESOLUTION_INCHES), then the image should be 2 inches wide when printed.
