Hi,
No, PDFBox always works through the whole page, and doesn't take into
account whether a part is displayed or not. The cropbox is just a clipping.

Hello,
I would like to use PDFBox to render technical plans in our editor on
background. To achieve smooth scrolling I need to be able to paint only visible
part of the PDF which might contain only small part of the whole PDF. We can
achieve it via setting CropBox, but unfortunately it looks like it doesn’t
affect rendering performance. Method renderPageToGraphics takes same time no
matter if whole page is rendered or small part of it.
So to me it looks like, even when CropBox is set the painting is done for whole
content and there is no performance boost.
Is there some way how to basically achieve that rendering of only 10% of page
will take 10% of time needed to render whole page?
Best regards,
