The Page Sorter Window as it is implemented in the sample application: Page.c. The parent window displays the currently selected image - 3.

Remarks:

The purpose of the page sorter window is to create a new multi-page file or to edit an existing one. When you're done editing the pages, you have the option to save out a single image file with multiple pages.

This function takes, as parameters, settings for the size and position of the page sorter, and returns you the handle of the new page sorter window. If there is no parent window, set hWndParent to NULL. The page sorter window will show small versions (thumbnails) of any file that is added to the page sorter window by the function IG_GUI_page_file_append(), or IG_GUI_page_insert().
