It is possible to add page labels to a document. These are not the printed on the page, but may be displayed alongside thumbnails or in print dialogue boxes by PDF readers. We use -add-page-labels to do this, by default with decimal arabic numbers (1,2,3...). We can add -label-style to choose what type of labels to add from these kinds:
| DecimalArabic | 1,2,3,4,5... |
| LowercaseRoman | i,ii,iii,iv,v... |
| UppercaseRoman | I,II,III,IV,V... |
| LowercaseLetters | a,b,c,...,z,aa,bb... |
| UppercaseLetters | A,B,C,...,Z,AA,BB... |
| NoLabelPrefixOnly | No number, but a prefix will be used if defined. |
We can use -label-prefix to add a textual prefix to each label. Consider a file with twenty pages and no current page labels (a PDF reader will assume 1,2,3...if there are none). We will add the following page labels:
i, ii, iii, iv, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, A-0, A-1, A-2, A-3, A-4, A-5
Here are the commands, in order:
By default the labels begin at page number 1 for each range. To override this, we can use -label-startval (we used in the final command), where we want the numbers to begin at zero rather than one.
Page labels may be removed altogether by using -remove-page-labels command.
