PDF Embedded text data overwrites on the image


we have converted a pdf(OCR data embedded) to tiff image. after converting it to tiff the OCR character are printed slightly above the text with different font size. really those are junk characters which produced by OCR

This issue is occurring on random cases.

Here is the code snippet.

using (Aspose.Pdf.Document pdfDocument = pdfDoc)
Resolution resolution = new Resolution(300);

TiffSettings tiffSettings = new TiffSettings();
tiffSettings.Compression = Aspose.Pdf.Devices.CompressionType.CCITT4;
tiffSettings.Depth = ColorDepth.Default;
tiffSettings.SkipBlankPages = false;
TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings);
tiffDevice.Process(“d:\test\input.pdf”, “d:\test\output.tif”);
