With this filter it is possible to filter an area over all pages for the comparison. The filtered area(s) to compare can be specified semicolon separated. If no value is specified, then no areas will be filtered. All elements contained inside these areas will be filtered.

An area is defined with 4 integer parameters (x, y, width, height). Each parameter is separated with a comma. Empty parameter is equal to 0. The values are in 'pixels' with a resolution of 72 DPI. This resolution is used to calculate the default rendering size of a page as well. For example an US-Letter sized page in portrait orientation has 612 x 792 pixels. The values are relative to the pages as they would be displayed at 72 DPI. A different screen resolution will have no effect to the area filter.

Multiple areas are supported. Use ; to separate the area definitions.

With optional parameters it is possible to specify the page number and/or the document on which this area will be filtered. Available values for page number are 1 to max. document page number. With no declaration, the area will be filtered for all pages. Available values for documents are 'F' for first document or 'S' for second document. With no declaration, the area will be filtered for both documents

Samples:

• 0,0,100,100
• ,,100,100
• 5,5,10,10;50,10,50,50 (two areas)
• 0,0,100,100,1 (only valid for the first page)
• 50,50,100,100,F (area for all pages but only for the first document)
• 100,10,200,200,3,S (area for the 3.page for the second document)

This option specifies whether the set areas should be excluded or not. When activated, all elements of the entire page are filtered out and only the area(s) are used for the comparison.
