MediaBox, CropBox, and Viewport Logic
Technical cropping in a PDF is done by modifying the page boundaries: 1. CropBox Entry: We don't delete the 'hidden' content (for safety). Instead, we modify the `/CropBox` entry in the PDF dictionary, which tells the viewer what area to display. 2. Coordinate Normalization: We ensure that even if the page is cropped, any existing links or annotations are still correctly positioned within the new view. 3. Content Isolation: By redefining the boundaries, we ensure that during printing, only the selected area is transferred to paper.
