The
Bitmap Tool can create and graphically locate the differences between two bitmaps. You can use all Windows functionality to resize, save,
and otherwise manipulate bitmaps, in addition to the special comparison features included in the tool.
Using the
Bitmap Tool, you can:
- Show the areas of difference.
- Zoom in on the differences.
- Jump from one zoomed difference to the next.
- View on-line statistics about the bitmaps.
- Edit (copy and paste), print, and save bitmaps.
- Create masks.
The
Bitmap Tool has the following major comparison commands:
- Command
- Description
- Show
- 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.
- Zoom
-
Creates a special, not sizable,
Zoom window with three panes and resizes and stacks the
Baseline,
Differences, and
Result windows.
- The top pane of the
Zoom window contains a zoomed portion of the
Baseline window.
- The middle pane shows a zoomed portion of the
Differences window.
- The bottom pane shows a zoomed portion of the
Result 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.
While in scan mode, you can capture the
Zoom window to examine a specific bitmap difference.
- Scan
- The tool indicates the location of the first difference it finds by placing a square in the same relative location of the
Baseline,
Result, and
Differences windows. The three panes of the
Zoom window also show the difference.
- Comparison Statistics
- Provides statistics about the bitmaps.
You can also compare bitmaps by creating and applying masks.
