To compare files, PowerWeb displays a unique viewing page that shows the renditions of the selected documents. The two files can be two revisions of the same rendition file or two similar but unrelated renditions that you want to compare visually. The page allows you to see either of the renditions alone or a simultaneous view of both renditions that displays the additions, deletions, and unchanged objects between the two files in symbolic colors:
-
Green: additions
-
Red: deletions
-
Black: unchanged
To compare files, PowerUser displays a unique multi-pane window. Two of the panes show two files side-by-side. The two files can be two revisions of the same source or rendition file or two similar but unrelated files that you want to compare visually. The area of the files shown in the two panes are synchronized with one another. When you change the view of one file, the view of the other file is changed automatically to match the first file. This makes it easy to compare files without adjusting the views, sizes, and positions of separate windows.
If the files being compared are supported vector (CAD) graphics files, the lower-right pane shows the additions, deletions, and unchanged objects between the two files in configurable colors. The lower-left pane contains options to change the colors. This graphical representation of changes is valuable for quickly determining the differences between two complex files. You can print a hard copy of the differences and also generate a report of the non-graphical differences between two files, for example, layer names, system variables, and so on.
-
Comparing renditions is supported by the built-in PDFTron viewer.
-
Graphics that have been moved but that are otherwise unchanged are considered by Compare as a deletion from one document and an addition to the other document.
