We developed a PDF editor using aspose pdf that allows user to redact and rotate pages. Most of the pdfs that we tested it with work fine. However some pdfs cause unusual errors with both redaction and rotation. Here is a brief summary of the issues and I have attached a console app with the sample pdfs.
- When we add redaction at the top, it appears at the bottom in the output. The redaction is rotated at -90 degree in the process
2.When we add redaction at the top, it seems to highlight the entire page.
- When we rotate a page and generate the png out of it for rendering it in browser, that png image is not correctly formatted.
