I managed to do this with CROPBOX , but the problem is that this will make the pages smaller by removing the top part. Can someone help me to implement this so the page size remains the same. My idea would be to override the top page with a white rectangle, but after many tries I didn't manage to do this. This is the current code I'm

问题 Before asking my question, I have a test page to make it everyone understand my question better. The URL is http://iamthemoon.com/crop/ You can move the red selection. I like to crop only the area of red selection. I thought it could be done easily in HTML5 canvas, but that was my mistake. First I googled about it 2 days, but I couldn't find a solution.

由 一世执手 提交于 2019-12-06 16:53:33
I don't know how to tag this question, please edit if possible. The job: Create an application which can auto-crop black borders in images in batch runs. Images vary in quality from 100-300dpi, 1bpp-24bpp and a batch can vary from 10 - 10 000 images.
