Description

Hi,

we use pdfbox to render documents. Now we have scanned documents here, that renders with black points:

But Acrobat Reader shows this:

Simple usage:

PDFRenderer renderer = new PDFRenderer(pdfFile);
renderer.setSubsamplingAllowed(true);
renderer.setDefaultDestination(RenderDestination.VIEW);
BufferedImage rimg = renderer.renderImage(...)
...
g.drawImage(rimg...) 

pdfbox 2.0.24
