The hidden structure of the VMS

[Jorge_Stolfi]

The following shows a heatmap that reflects the % of all pages that have text in a given area. The horizontal bars represent image breaks that occur.

To make this heatmap you aligned the text areas on each page so that the first text line is at the same Y coordinate, right?  That is, the Y coordinate of a line is not relative to the top edge of the vellum, but relative to the first text line on the page, correct?

All the best, --stolfi
