Specifies GUI Select tool control options.
IG_GUI_SELECT_ASPECT | Controls aspect correction of the GUI Selection rectangle. If aspect ratio preservation is in effect for the image (i.e. the HIGEAR image's aspect ratio setting is IG_DSPL_ASPECT_FIXED) and this option is set to TRUE then the rectangle which the user draws out will automatically be aspect-ratio corrected. |
See IG_GUI_select_attribute_set for more details.
