Hi Tilman,
Thanks for the quick answer,
Inserting TIFF images in the 1.8 versions can only be done for G3 or
G4 compressed images, with PDCcitt.
As far as I understand, G3 and G4 are for bitonal images. Does it mean
that there is no way to insert
CMYK images in a pdf ?
Is there any reason not to allow a (in-memory) BufferedImage using a 4
components CMYK ColorSpace
to be used in PDPixelMap ?
Inserting RGB BufferedImages should work with PDPixelMap. If it
doesn't in 1.8.5, this would be embarassing because I worked on that
one. Please open an issue in JIRA, attach the code and the image.
OK, I tested again with your code (just replaced the new File( image ) by
an in-memory empty BufferedImage created withTYPE_4BYTE_ABGR),
I observed 3 differences (in the pdf file edited with a text editor) :
1 -
1.8.4 :*/ColorSpace /DeviceGray*
1.8.5*: /ColorSpace /DeviceRGB*
2 - octet streams are not the same
3 - last obj (#10) refer to a different integer (does not know what it
means though)
1.8.4
10 0 obj
33
endobj
1.8.5
10 0 obj
52
endobj
Despite that 1.8.5 colorspace declaration seems more
correct, result from 1.8.4 displays correctly in Acrobat
and pdf generated wit 1.8.5 does not open.
Let me know if I can help more,
Michaël
Your source code should look somewhat like this:
doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage( page );
BufferedImage awtImage = ImageIO.read( new File( image
) );
ximage = new PDPixelMap(doc, awtImage);
PDPageContentStream contentStream = new
PDPageContentStream(doc, page);
//contentStream.drawImage(ximage, 20, 20 );
// better method inspired by
http://stackoverflow.com/a/22318681/535646
float scale = 1f; // reduce this value if the image is too
large
contentStream.drawXObject(ximage, 20, 20,
ximage.getWidth()*scale, ximage.getHeight()*scale);
contentStream.close();
doc.save( file );

Hi,
I want to insert a cmyk image in a pdf document.
Here is what I've tried :
- Create a BufferedImage with a CMYK type ColorSpace
- Set some pixels programatically
- Insert the BufferedImage in the document with PDPixelMap
==> Throws a IllegalStateException (which is consistent with the code
which checks that ColorSpace has 1 or 3 components) :-(
I've also tried to save my BufferedImage as a Tiff with Commons Imaging,
which works fine, but If I try to include it as a PDPixelMap, I have the
same error as above, and if I compress it as a CCITT image, It
converts it
to black/white. Which kind of tiff can I include in a pdf exactly ?
Finally, I had a try with PdfBox 1.8.5 (previous tests were with
1.8.4), but
with 1.8.5, inserting a RGB BufferedImage, which works fine with 1.8.4,
creates a PDF I can't open with acrobat reader :-(
Any hint about one of these problem is welcome,
Michaël
