[Feature Request]: Blending all pages in PDF over before selecting crop area

Open 3engel opened this issue 10 months ago • 3 comments

Feature Description

Before cropping a multipage PDF, it would be very helpful if all pages within the PDF will be blended over in the UI preview.

Why is this feature valuable?

Users are able to select a valid crop frame for the complete PDF and they will not crop information in pages which are offset compared to the first page of the PDF.

Suggested Implementation

The implementation here https://www.sejda.com/en/crop-pdf is pretty good.

Can you explain what you mean by 'blending' ?

@Frooodle In the example image, all pages of a PDF have been superimposed. This allows you to see relatively quickly how you can crop the PDF without accidentally cutting off content on individual pages.

I guess white backgrounds need to be transparent to make that work. I hope that makes it clearer.
