Dominic Tubach commented on PDFBOX-2288:
----------------------------------------
png works as well as other encoders. Nevertheless it should work with bmp, too.
> Defective BufferedImage for flate encoded images
> ------------------------------------------------
>
> Key: PDFBOX-2288
> URL: https://issues.apache.org/jira/browse/PDFBOX-2288
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.0
> Reporter: Dominic Tubach
> Attachments: test.pdf
>
>
> The BufferedImages for flate encoded images seem to be defective. The
> following code results in a ArrayIndexOutOfBoundsException when writing the
> image:
> {code}
> PDDocument doc = PDDocument.load("test.pdf");
> Iterator<PDXObject> it =
> doc.getPage(0).getResources().getXObjects().values().iterator();
> PDImageXObject image = (PDImageXObject) it.next();
> BufferedImage bi = image.getImage();
> try (FileOutputStream fos = new FileOutputStream("test.bmp")) {
> ImageIO.write(bi, "bmp", fos);
> }
> {code}
> The problem did not exist in 1.8. The attached PDF just contains one flate
> encoded image.
