// for barcode reading
LeadBarCode1.BitMap := LeadImage2.OCXBitmap;
.........

LeadImage2.Save('c:\aaa',FILE_CCITT_GROUP4,1,PQ1,SAVE_OVERWRITE);

// for ocr loading image file
nRet:= LEADRasterIO1.Load ( LeadRaster1 ,'c:\aaa', 0, 0, 1 );
if ( nRet <> 0 ) then
begin
ShowMessage ( 'Error loading file' );
exit;
end;

nRet:= LEADRasterDocument1.AddPage ( LeadRaster1, 0 );
if ( nRet = 0 ) then LEADRasterView1.Raster.Bitmap := LeadRaster1.Bitmap;

Hello,

You can copy the image from VCL LeadImage to LeadRaster by using the LEADImage.OCXBitmap as follows:
+----------+
LEADRasterView1.Raster.Bitmap := LEADImage1.OCXBitmap;
+----------+

Thanks,
