Hi,
I convert PDF to CCITT4 TIFF file using the following code:
Pdf.Facades.PdfConverter pdfConverter = new Pdf.Facades.PdfConverter();
Resolution resolution = new Resolution(300);
pdfConverter.Resolution = resolution;
pdfConverter.BindPdf(tbxSource.Text);
pdfConverter.DoConvert();
//create TiffSettings object and set CompressionType
TiffSettings tiffSettings = new TiffSettings();
tiffSettings.Compression = CompressionType.CCITT4;
tiffSettings.Depth = Pdf.Devices.ColorDepth.Format1bpp;
//convert to TIFF image
pdfConverter.SaveAsTIFF(tbxDestination.Text + “pdf.tif”, tiffSettings);
pdfConverter.Close();
The result image is generated using Threshold binarization method (no dithering).
I use Floyd Steinberg Dithering method when I create TIFF file from Aspose Words for .Net. and final image is perfect for faxing.
Does this setting exist in Aspose PDF? For us it is a core requirement for Faxing.
Thanks.
Hi Alex,
Thanks for your inquiry. I am afraid Aspose.Pdf does not support dithering. We have already logged a ticket PDFNEWNET-37514 in our issue tracking system for the purpose. We have linked your query to the issue id and we will notify you as soon as it is implemented.
We are sorry for the inconvenience caused.
Best Regards,
I am curious if this was ever implemented or ever will be?
