Subject: [iText-questions] Washed out (transparent) image
Hello fellow iTexters...
One the images that I am embedding in my PDF appears washed out in the final
output. The simplest test case is as follows:
Document doc = new Document(PageSize.A4);
PdfWriter.getInstance(doc, new FileOutputStream(new
File("washout.pdf")));
doc.open();
doc.add(Image.getInstance("checkpoints.png"));
doc.close();
The image appears in the PDF, but the colours are not the same as if you just
view the image directly. Note that I normally scale the image so that it fits
on the page, but I wanted to make the test case as simple as possible (you can
see the problem both with and without scaling).
I've attached the image and the resulting PDF, and they are also downloadable
from the following URLs in case they don't make it through:
http://dl.dropbox.com/u/48589982/checkpoints.png
http://dl.dropbox.com/u/48589982/washout.pdf
My initial googling suggests that I may need to set the color space, but I am
not 100% sure if a) that is really the problem and b) exactly what the sequence
of iText APIs I need to call if it is. Any thoughts/advice would be most
welcome. Thanks a lot.
Craig
