Remarks:
 |
The functionality of this API call has been upgraded and supported by the new function IG_GUI_page_window_create_ex(). The reason that this new function has been created is that the old function does not allow you to set the Windows Style bits. In the interest of backward compatibility, we have left the old function in its original form and have retained support for it. If you have already used the old function in your code, it is not mandatory that you modify your code, but it is recommended. |
This function creates a page sorter window. The purpose of the page sorter window is for creating a new multi-page file or to edit an existing one. When you're done editing pages, you have the option to save out a single image file with multiple pages.
|
For a screen capture of a GUI page sorter, see IG_GUI_page_window_create(). |
This function takes as parameters settings for the size and position of the page sorter, and returns 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().
- To move pages around (which effectively changes the numbering of the pages) hold down the Shift key while dragging with the left mouse button.
- To delete a page, select it with the mouse, and click the Delete key.
- To modify the size of the page "thumbnails" or to read their current size, use IG_GUI_page_thumbnail_size_set() and IG_GUI_page_thumbnail_size_get() functions, respectively.
- To save the pages into one multi-page file, set up a loop that will "page" through each HIGEAR image and append it to a multi-page file with a call to IG_save_file(). This is demonstrated in the example code.
