ExSp created PDFBOX-5816:
----------------------------
Summary: PDFRenderer.renderImage creates black line clouds on the
text
Key: PDFBOX-5816
URL: https://issues.apache.org/jira/browse/PDFBOX-5816
Project: PDFBox
Issue Type: Bug
Components: PDModel, Rendering
Affects Versions: 2.0.31, 2.0.30
Environment: Java 8
Reporter: ExSp
Attachments: image003.png, image0032.png
For some PDF files, the PDFRenderer.renderImage method creates an image with
black line clouds on the text that are not visible in the original PDF.
Unfortunately, the files contain personal data, so I cannot make them available
for examination. The attached screenshots hopefully give a first impression of
the problem. Is there any way for me to narrow down the problem or analyze the
PDF so that I can provide more information?
The source code does something like this:
{code:java}
try (PDDocument document = PDDocument.load(pdfData)) {
PDFRenderer pdfRenderer = new PDFRenderer(document);
int pageCount = document.getNumberOfPages();
for (int pageIndex = 0; pageIndex < pageCount; ++pageIndex) {
PDPage page = document.getPage(pageIndex);
BufferedImage pageImage = pdfRenderer.renderImage(pageIndex);
...
}
}{code}
