Tilman Hausherr created PDFBOX-2949:
---------------------------------------
Summary: Rendering to ARGB brings black background
Key: PDFBOX-2949
URL: https://issues.apache.org/jira/browse/PDFBOX-2949
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Tilman Hausherr
As reported by [~jon_wu] in the user mailing list... instead of the somewhat
long thread, here's code I tried:
{code}
try (PDDocument document = PDDocument.load(new File(dir, "dora.pdf")))
{
PDFRenderer pdfRenderer = new PDFRenderer(document);
BufferedImage bim = pdfRenderer.renderImageWithDPI(0, 300,
ImageType.RGB);
ImageIO.write(bim, "png", new File(dir, "dorargb.png"));
bim = pdfRenderer.renderImageWithDPI(0, 300, ImageType.ARGB);
ImageIO.write(bim, "png", new File(dir, "doraargb.png"));
}
{code}
PDFRenderer has this:
{code}
Graphics2D g = image.createGraphics();
if (imageType != ImageType.ARGB)
{
g.setBackground(Color.WHITE);
}
{code}
We could just remove the line with the "if" and the braces. The question is, is
the current behaviour a fault or a feature?
