An Image Filter plug-in is simply a DLL with the file extension .APL. It contains various filters that can be applied to images in Edit mode. These filters can only run on one layer of an image at a time. This DLL must export certain functions, as outlined below. After the plug-in is compiled, it must be placed in a host application-designated plug-in directory where the host application will detect and load it. NOTE: More than one filter can be included in one Image Filter plug-in. Refer to IF_GetPlugInInfo for more information. |
