The table below lists the GUI Page Settings and indicates the various attributes to which you should refer:

Image Control Constants	Type	Values Range
IG_GUI_PAGE_REALIZEPALETTETO	HWND	A window that contains the palette to use for the page thumbnails.
IG_GUI_PAGE_DRAGDROP	AT_BOOL	TRUE - moving page thumbnails is allowed within the page window if the SHIFT key is pressed.
IG_GUI_PAGE_ALIAS_THRESHOLD	UINT	Anti-aliasing threshold for 1-bit page thumbnails.

Currently it is possible to change font title for Page windows that is created by IG_GUI_page_window_create(). To set the font use IG_GUI_page_attribute_set() and to get the font, use IG_GUI_page_attribute_get() with the IG_GUI_PAGE_FONT_TITLE option. As in the case of thumbnail window, the user is responsible for creating and deleting the font. See the example below.
