Tilman Hausherr commented on PDFBOX-2057:
-----------------------------------------
I have adjusted the code so that a mask is always created with a gray
colorspace. I decided to avoid the DeviceGray colorspace for gray images
because image colors are somewhat too light in the 1.8 branch, which is why I
saved them as RGB. The change makes an exception for masks. I also added a test
that checks this. This was done in rev 1592410. You can try a snapshot within a
few hours here
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox/1.8.6-SNAPSHOT/
Next thing I'll do it to see whether we can handle TYPE_INT_ARGB, and check
whether the (unreleased) 2.0 version also at risk. Re: CMYK, the best is always
to prove code that fails. I don't know if it will be possible, the 1.8 branch
has trouble with that.
> Importing BufferedImage in PDFBox 1.8.5 broken
> ----------------------------------------------
>
> Key: PDFBOX-2057
> URL: https://issues.apache.org/jira/browse/PDFBOX-2057
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.5
> Environment: windows vista / jdk 1.7.0_45
> Reporter: Michaël Michaud
>
> Try to import a BufferedImage in a PDDocument with PDPixelMap
> BufferedImage with TYPE_4BYTE_ABGR works fine with PDFBox 1.8.4 (though, the
> pdf file contains instruction /ColorSpace /DeviceGray)
> BufferedImage with TYPE_4BYTE_ABGR produces an unreadable PDF with PDFBox
> 1.8.5 (though, the pdf file contains instruction /ColorSpace /DeviceRGB).
> Code used to demonstrate the problem is as follows (image has also been
> colored with some Graphics instructions to demonstrate that 1.8.4 is working)
> :
> {code}
> try {
> PDDocument doc = new PDDocument();
> PDPage page = new PDPage();
> doc.addPage(page);
> BufferedImage awtImage = new BufferedImage(100,100,
> BufferedImage.TYPE_4BYTE_ABGR);
> PDPixelMap ximage = new PDPixelMap(doc, awtImage);
> PDPageContentStream contentStream = new PDPageContentStream(doc,
> page);
> contentStream.drawXObject(ximage, 200, 200, 100, 100);
> contentStream.close();
> doc.save("C:\\Temp\\PDF\\test185_4babgr.pdf");
> } catch(COSVisitorException|IOException e) {
> e.printStackTrace();
> }
> {code}
> I also tried with a BufferedImage with TYPE_INT_ARGB but it throws an
> exception with PDFBox 1.8.4 and 1.8.5 :
> {code}
> Exception in thread "main" java.lang.IllegalArgumentException: Raster
> IntegerInterleavedRaster: width = 100 height = 100 #Bands = 1 xOff = 0 yOff =
> 0 dataOffset[0] 0 is incompatible with ColorModel ColorModel: #pixelBits = 8
> numComponents = 1 color space = java.awt.color.ICC_ColorSpace@1dc80063
> transparency = 1 has alpha = false isAlphaPre = false
> at java.awt.image.BufferedImage.<init>(BufferedImage.java:630)
> at
> org.apache.pdfbox.pdmodel.graphics.xobject.PDPixelMap.createImageStream(PDPixelMap.java:107)
> {code}
> My main purpose was to use a BufferedImage with a CMYK ColorSpace, but
> PDPixelMap seems to accept 1 component and 3 component ColorSpace only.
