typedef BOOL (ACCUAPI *LPFNIG_ART_POSTREATENOTIFYFUNC)( HIGEAR hIGear, LPVOID lpPrivate, ART_MARK_INDEX hMarkIndex, LPART_MARK_ATTRIBUTES lpMarkAttr ); |
Name | Type | Description |
hIGear | HIGEAR | HIGEAR handle of an image. |
lpPrivate | LPVOID | A far pointer to the private callback data. |
hMarkIndex | ART_MARK_INDEX | The index number (identifier) for the new mark. |
lpMarkAttr | LPART_MARK_ATTRIBUTES | A far pointer to an ART-defined attribute structure of type ART_MARK_ATTRIBUTES. This can be used to override the default mark attributes before the new created mark is displayed. |
Returns TRUE - the mark attributes are changed; FALSE - no change.
All pixel formats supported by ImageGear Professional.
The MarkIndex passed into the callback is the MarkIndex of the created mark. This callback function gives the developer an opportunity to change any default named blocks or the mark attributes of the mark that is just created.
The callback for "Post create" occurs just after the end user draws the mark. For example, if the user draws a line, LPFNIG_ART_POSTCREATENOTIFYFUNC is called when the right mouse button is released and when the mark and all mark named blocks are created.
In order to use this callback, it must be registered with ART using the function ART_callback_register(). |
