I try to make a monochrome tiff image to transparent with MakeMask() in a PDF.
It works on a CCITTT6 Tiff image, However when I do with a PackedBit Tiff Image, Its color was inverted after img.MakeMask(), and the content become transparent. Then I try to trace with iTextSharp's Source code, and I found the function GetTiffImageColor() in iTextSharp.text.pdf.codec.TiffImage have something strange as below if (photometric == TIFFConstants.PHOTOMETRIC_MINISWHITE) img.Inverted = true; As I know,photometric MINISWHITE is the default setting that when a bit is 0, it show as "WHITE". and MINISBLACK will show as "BLACK". Thus I modify the photometric to PHOTOMETRIC_MINISBLACK, and everything work now. Is it a bug? -- View this message in context: http://itext-general.2136553.n4.nabble.com/Color-Inverted-after-MakeMask-of-a-Packedbit-TIFF-image-tp4656903.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Everyone hates slow websites.
