Description

I try to convert a pdf file with transparent images to a image but the opacity is lost in the png result.

It's seem to be the same issue than https://issues.apache.org/jira/browse/PDFBOX-993 (fixed in 1.6.0).

I test with code: (1.8.7)
pdPage.convertToImage(BufferedImage.TYPE_4BYTE_ABGR, 72);

and with:
java -jar pdfbox-app-1.8.7.jar PDFToImage -imageType png test.pdf
