Hi,
we are using PDFBox to add/modify annotations of a PDF file with showing a preview to the user. This works well: let PDFBox rendering the PDF (with annotations included), showing the image to the user.
But when using complex and big PDF files, it may take some seconds to render the complete page. That's not bad, when only doing this once. But we want to update the preview after every annotation change.
So the idea is: let PDFBox render the PDF without the annotations once. Caching the resulting image (base). Now it would be great, to let PDFBox render only the annotations after every change. So the preview would be much faster: painting the cached (base) image and painting the annotation-image. Is this possible?
Thanks a lot, jens --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@pdfbox.apache.org For additional commands, e-mail: users-h...@pdfbox.apache.org
