int IMAPI ImgPlugInInvoke (hImage, hOwner, rect )

This causes the currently loaded plug-in to display its U/I or to begin processing of the image if the plug-in has no U/I.

 

Parameter	Type	Description
hImage	HANDLE	A handle to an ImageMan image handle.
hOwner	HWND	The handle of the parent window.
rect	RECT	The portion of the image that the filter is to perform its operations on or NULL for the entire image.

Return Value

Return IMG_OK if successful, otherwise IMG_ERR and IMGPI_PLUGINERROR will be returned by ImgGetStatus().

Comments

You can only invoke a plug-in only on 24 bit raster images. You will get IMG_BAD_TYPE if you try this on a vector image or non-24bit image.

Example

int iErr;

if ( (iErr=ImgPlugInLoadSpecific(  coolplug.8bf )) == IMG_OK ) {

iErr = ImgPlugInInvoke( hImage, hWnd, NULL ) ;

if ( iErr != IMG_OK ) {

ImgErrBox () ;

return ;

}

}

// now you can go on to draw the filtered image!
