You can, if you want, save the bitmaps you have captured in the Bitmap Tool. You should adopt a naming convention that helps you distinguish between the first bitmap in the comparison, called the baseline bitmap, and the second bitmap, called the result bitmap. You can make the distinction in the file name itself, for example, by appending or prefixing a b or r to the name and using the same file extension for all bitmap files. Or you might use the same file name for both baseline and result bitmaps and add a unique file extension.
You save baseline and result bitmaps of the Open dialog box as open.bmp and open.rmp. Alternatively, you might name them openbase.bmp and openres.bmp, respectively.
The following table lists the file extensions supported by the Bitmap Tool. We recommend that you use .bmp for baseline bitmaps and .rmp for result bitmaps.
| If you are saving | And you want the file name to be | Then use this extension |
|---|---|---|
| Baseline bitmap | Identical to the result bitmap’s | .bmp |
| Result bitmap | Identical to the baseline bitmap’s | .rmp |
| Either baseline or result bitmap | Unique | .bmp or .dib (Device Independent Bitmap) |
