API Reference Guide > Core Component API Reference > Core Component Callback Functions Reference > LPFNIG_RASTER_PLANE_SET

This function is called by ImageGear to let your application store or process each color plane raster, as it is obtained from the file.


Copy Code
        AT_VOID* lpPrivate, 
        const AT_VOID* lpRast, 
        AT_PIXPOS cyPos, 
        AT_INT cRasterSize, 
        AT_INT nBitPlane


Name Type Description
lpPrivate AT_VOID* A far pointer to a private data area.
lpRast const AT_VOID* Raster line to set.
cyPos AT_PIXPOS Y position in the image.
cRasterSize AT_INT Size of the raster line.
nBitPlane AT_INT Index of the color plane in which to merge.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

This function does not process image pixels.


ImageGear calls this function to pass raster plane data that has been read from a file to the application. The callback is invoked when reading images where pixel data is stored in planar format. Currently, only TIFF and DICOM format filters support this callback.
