Comparing bitmaps
Showing areas of
difference
The Show command creates a Differences window, which is a child window
containing a black-and-white bitmap. Black represents areas with no
differences and white represents areas with differences.
Procedure To graphically show areas of difference between a baseline and a
result bitmap, click Differences/Show.
The bitmap tool displays a Differences window along with the source
baseline and result bitmaps from which it was derived.
Zooming in on the
differences
The Zoom command creates a special (not sizable) Zoom window with three
panes and resizes and stacks the Baseline, Differences, and Result window.
The top pane of the Zoom window contains a zoomed portion of the Baseline
Bitmap window.The middle pane shows a zoomed portion of the Differences
window. The bottom pane shows a zoomed portion of the Result Bitmap
window. All three zoomed portions show the same part of the bitmap. When
you move the mouse within any of the three windows, the bitmap tool
generates a simultaneous and synchronized real-time display in all three
panes of the Zoom window.
