Thanks for the reply. So what I'm doing is 1. use PdfStamper to read an existing pdf and add some formfields onto it 2. use PdfStamper to fill out the formfields in BaseColor.Blue, add a PNG image on the first page and flatten the document.
All went well except the text I filled in the page with PNG image will be darker than other pages due to the color space issue.(see attached sample) http://itext-general.2136553.n4.nabble.com/file/n4654689/example.pdf example.pdf I don't think it's an issue cause by iText because it happens too when I copy-paste an PNG image in Acrobat. I tried to manually change the color space right after I instanciate the PdfStamper but it's not working, the text is still darker: --------------------------------------- PdfReader r = null; PdfStamper ps = null; FileStream outstream = null; // read existing PDF document r = new PdfReader( new RandomAccessFileOrArray(this.inputFileName), null); outstream = File.Create(this.outputFileName); ps = new PdfStamper(r, outstream); PdfDictionary pp = new PdfDictionary(); pp.Put(PdfName.TYPE, PdfName.GROUP); pp.Put(PdfName.S, PdfName.TRANSPARENCY); pp.Put(PdfName.CS, PdfName.DEVICERGB); PdfContentByte cb = ps.GetOverContent(1); cb.PdfWriter.Group = pp; cb.SetDefaultColorspace(PdfName.CS, PdfName.DEVICERGB); //...create textfield //...fill out textfield //...add PNG image ps.FormFlattening = true; ps.Close(); -- View this message in context: http://itext-general.2136553.n4.nabble.com/text-color-changes-when-adding-PNG-image-tp4653811p4654689.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
