-----------------------------------------------------------------
Thank you [~chupacabras]! I'm surprised myself that it works, because I once
looked into these raster arrays while debugging, and the alpha values were
either in the highest byte or in every fourth byte, so I'm surprised that it
ends at the correct place. I committed the change in rev 1593329 for the trunk.

> Importing BufferedImage into PDPixelMap is broken in 1.8.5

> Key: PDFBOX-2057
> URL: https://issues.apache.org/jira/browse/PDFBOX-2057
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.5, 1.8.6
> Environment: windows vista / jdk 1.7.0_45
> Reporter: Michaël Michaud
> Assignee: Tilman Hausherr
> Labels: regression
> Fix For: 1.8.6, 2.0.0

> 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.
