Headers and Footers

This filter can be used to exclude headings and footers from the comparison that leads to the reduction of repeating differences. Automatic detection is only possible in non-strict mode. Three options are available.

  • Do not recognize Headers and footers are not recognized
  • Automatically Detect Headers and footers are automatically recognized and treated by PDFC
  • Manually set Headers and footers allow you to precisely adjust pixels if the areas can not be detected automatically.

Paging and sections

The Header and Footer filter detects recurring areas at the top and bottom page edges or lets you define their sizes manually. This allows header and footer areas without relevant differences to be excluded from the comparison.

The selection provides the following values:

  • Don't detect disables header and footer detection and processing by this filter.
  • Auto detect analyzes the documents and tries to detect stable header and footer areas automatically.
  • Set manually shows the separate Header Size and Footer Size controls. You can set both values from 0 to 200 pixels.

Automatic detection can be used independently of the comparison mode. If the preview shows edges or handles for the area boundaries, drag the respective handle to adjust the header or footer size.

Important: Define the areas no larger than necessary. Header or footer areas that are too large can exclude relevant document content near the page edges from the comparison.

Manually configured header and footer areas, each set to 80 px.
