Page

Using the Page property, you can perform the following checks:

Page box layout: This check allows you to trace whether in the document there are instances where the page box layout does not conform with the screen layout of a PDF document.
Position media box: This checks the position of the media box.
Different page sizes: Checks whether some of the pages in the PDF document have a different size else there may be problems while printing or processing the document.
Different page orientations: Checks whether all the pages in the PDF document use the same page orientation. A page can have either landscape or portrait orientation.
Page size: Checks whether some of the pages in the PDF document conform to the exact page size indicated or not. The precision is set to 5 pt (points) by default but you can change it to a value of your choice. A precision of 0 means the size or position needs to be exact, so if you are checking for a height of 10 inch and the page box height is 10.001 inch, an error or warning will be displayed in the report.

Note: Here the tolerance for matching PageSize with an available media size is 5 default user space units in either dimension. The "default user space units" is PostScript points, which is 1/72 of an inch. Therefore 5 default user space converts to 1.76mm.
Page is scaled: Checks if a page scaling factor is used. You can apply or remove the page scaling factor. When you "apply" the page scaling factor, the page scaling will be removed without affecting the appearance of the page, that is, the contents of the page will be scaled to compensate. When you "remove" the page scaling factor, the page will revert to its original size.
Empty page: Checks if any of the pages are empty and warns if empty pages are found.
Number of pages: Checks on of the following:
- Exact number of pages in the document.
- Whether the number of pages in the document are even or odd.
- whether the number of pages in the document is a multiple of a number of your choice.
Objects outside page box: Checks the document for any graphics located outside the specified page box.
Page size: fit to columns: Checks whether any pages in the PDF document have a horizontal page size (width) which is not a multiple of a specific number of points. Also checks the distance between the columns in the document.
Page size: fit to rows: Checks whether any pages in the PDF document have a vertical page size (height) which is not a multiple of a specific number of points. Also checks the distance between the rows in the document.
Safe type zone: Checks the document for any graphics that overlap with the specified page box.
Bleed: Check if the objects have enough bleed.
