JanN	Posted - Oct 30 2012 : 08:59:24 Hi, I already could build TIFF G4 files out of JPEG files. But somehow my code doesn't work in this particular case. I have an RGB TIFF file and want to convert it to BW. But whatever I do, it seems there is no difference between input and output file. I tried two approaches: Tiff.IO.LoadFromFile(inputfile, ioTIFF); Tiff.IO.Params.TIFF_Compression := TIOTIFFCompression.ioTIFF_G4FAX; Tiff.IO.Params.TIFF_PhotometInterpret := ioTIFF_BLACKISZERO; Tiff.IO.Params.BitsPerSample := 1; Tiff.IO.Params.SamplesPerPixel := 1; Tiff.IO.Params.ImageIndex := i-1; Tiff.IO.SaveToFileTIFF(outputfile) Tiff.IO.LoadFromFile(inputfile, ioTIFF); Tiff.Proc.ConvertToBW_FloydSteinberg; Tiff.IO.SaveToFileTIFF(outputfile) Is there anything wrong with my code? Could it be the original TIFF file which causes problems? Regards, Jan
