3. Document properties for the selected PDF document

This area of the PAC user interface displays additional information about the PDF document that is being checked. These details include the title, file name, main language, number of tags, number of pages, and the file size.

Using the detailed report, individual errors (checkpoints) can be analyzed and located in the document. Items can be expanded in the Title list to view details about subitems.

When an error in the list is clicked, details about the error are displayed in the top-right pane, and the location of the error in the document is displayed in the lower-right pane.

Summary test reports, as proof of quality, can be exported using this button.

A list of the tags that are used in the PDF document, as well as the count for each type of tag can be reviewed using this button. This information can help to evaluate the document semantics.
