I have RasterImaging 14.0 and try to use the "Copy" function of the "Raster" object for Copy RGN to the clipboard but does't work.

short sReturn = 0;

sReturn = m_LEADRasterView1.GetRaster().SetRgnRect(100,100,100,100, L_RGN_SET);

sReturn = m_LEADRasterView1.GetRaster().Copy(COPY_EMPTY | COPY_DIB | COPY_PALETTE | COPY_RGN);

sReturn = m_LEADRasterView2.GetRaster().Paste(PASTE_DOPASTE);


but send all the image.

Please help me!!!
Thanks.

The COPY_RGN flag does not mean "copy region only".
It means "In addition to copying full bitmap, also copy region information".

If you want to copy only the region area, create an empty bitmap in a temporary LEADRaster object and copy the region pixels from the original object to the temp object using LEADRasterProcess.Combine().
Then use the Copy() method of the temp object to copy to clipboard.

sReturn = m_leadRasterProcess.Trim(m_leadRaster, fLeft, fTop, fWidth, fHeight);
sReturn = m_leadRaster.Copy(LTRASTERLib.RasterCopyConstants.COPY_EMPTY | LTRASTERLib.RasterCopyConstants.COPY_DIB | LTRASTERLib.RasterCopyConstants.COPY_PALETTE);

This will throw away the rest of the image, but it could work if you don't need the original image to stay the same.
