[jira] [Commented] (PDFBOX-2057) Importing BufferedImage into PDPixelMap is broken in 1.8.5

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-2057?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13990795#comment-13990795 ] 

Tilman Hausherr commented on PDFBOX-2057:
-----------------------------------------

I have improved PDPixelMap and its tests in rev 1592793. Masks are now supported for TYPE_4BYTE_ABGR and TYPE_INT_ARGB. I have also found a way to support grayscale images in the 1.8 branch: since they are read into the raster, I have to write them from the raster and not from the getRGB call because java does some modifications with the values.

Next thing I'll add some tests to the trunk to check whether it has the same problems.

[~Michaël] please test the snapshot when it is available.

>          Components: PDModel
>    Affects Versions: 1.8.5
>         Environment: windows vista / jdk 1.7.0_45

> 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.
