Direct access functionality, Page properties

Version history

This function was introduced in Quick PDF Library version 7.22.


Sets the dimensions of the specified page's boundary rectangles.

The MediaBox represents the physical medium of the page.

The CropBox represents the visible region of the page, the contents will be clipped to this region.

The BleedBox is similar to the CropBox, but is the rectangle used in a production environment.

The TrimBox indicates the intended dimensions of the finished page after trimming, and the ArtBox defines the extent of the page's meaningful content as intended by the page's creator.

Note that the parameters of this function are different to the SetPageBox function. This function uses X2 and Y2 rather than Width and Height.

By default coordinates are measured in points from the bottom left corner of the page, this can be changed using the SetGlobalOrigin and SetGlobalMeasurementUnits function.
