Hi, i used your sample code:
AsposePdf.Document pdfDocument = new AsposePdf.Document(@"D:\input.pdf");
AsposePdf.ImageStamp imageStamp = new AsposePdf.ImageStamp(@"D:\myImage.png");
imageStamp.XIndent = 100;
imageStamp.YIndent = 600;
imageStamp.Quality = 100;
pdfDocument.Pages[1].AddStamp(imageStamp);
pdfDocument.Save(@"D:\output.pdf");
Why the quality of the image stamp in PDF document document is so bad ? (even if I use imageStamp.Quality = 100;) Why I receive this yellow ring with grey quasi border? There is no border in original image on yellow ring. The original image has transparent background.
How can I get 1:1 stamp image from png image file without loosing quality?
