[jira] [Commented] (PDFBOX-1548) PDJpeg gots drawn in wrong colors when resized -> Adobe Reader -> Windows XP & 7

Andreas Lehmkühler commented on PDFBOX-1548:
--------------------------------------------

I guess the problem is that you are trying to resize the image by calling setWidth/setHeight. Instead you should resize them by using a transformation matrix, see PDPageContentStream#drawXObject.

> When creating a PDF and drawing PDJpegs to it, the images' colors are changed / inverted when resizing the PDJpeg(s) before drawing them to the PDF. This issue is only visible on Windows XP and Windows 7 using e.g. Adobe Reader. Preview on Mac or the new PDF-previewer build in Windows 8 is somehow not affected by this.
> This is what I do in code:
> 1.) Create PDDocument
> 2.) Create HashMap of PDJpegs (for caching purpose):
>      - Create PDJpegs by BufferedImage initialised through ImageIO.read()
>      - Resize PDJpegs by calling setHeight() and setWidth()
>      - Adding PDJpeg to HashMap
> 3.) Create PDPage and add it to PDDocument
> 4.) Create PDPageContentStream
> 5.) Draw some PDJpegs on the PDPage
> 6.) Close PDPageContentStream
> 7.) Save PDDocument
> 8.) Close PDDocument
> If the BufferedImages are resized before initialising the PDJpegs, everything works fine, but they don't look that sharp.
> Please provide some help, since I'm hanging on this for days now.
