Provides settings that define page boundaries for specific content types.
A PDF page content can be published using one of the following mediums.
- Finished medium (e.g., a sheet of paper).
Intermediate medium (e.g., film or an imposed reproduction plate).
The intermediate page may often include additional production-related content (such as bleeds or printer marks) that falls outside the boundaries of the finished page.
To support these publishing mediums, a PDF page may define the following additional boundaries.
- The page boundaries displayed in a PDF Viewer are defined by the PdfPageTreeObject.CropBox.
- The crop, bleed, trim, and art boxes should not extend beyond the boundaries of the PdfPageTreeObject.MediaBox. Otherwise, they are effectively reduced to their intersection with the media box.
