Differences List

The Differences List displays a list of the items that failed during playback. The Left,
Right, Top, and Bottom columns represent the measurement of the sides of the
difference area, in numbers of pixels. The number in the Left column is the number of
pixels from the left margin to the left edge of the difference region. The number in the
Right column is the number of pixels from the left margin to the right edge of the
difference region. In the same manner, the Top and Bottom columns define the
number of pixels to the top and bottom edges of the difference region, from the top
margin.

To work in the Differences List:

Use the vertical scroll bar to scroll through the list of descriptions.

Select a description in the Differences list to highlight the failure in the Baseline
and Actual files.

Double-click an item in the list to position the image so that the region is centered
in the view. It flashes briefly and then is selected.

The Difference list is sortable by column. The currently sorted column is indicated
with an asterisk. To sort by a different column, click the column header. The list is
sorted in ascending order of the selected column.

Mask/OCR List

Masks are used to hide the underlying masked area from comparison when test
scripts are played back. Any areas of the image that contain a mask are not compared
when you play back a test script containing an Image verification point.

Robot uses OCR regions to read the text within a designated region and to compare it
in subsequent playbacks of the test script.

The Mask/OCR List in the lower-left pane of the main window lists any masks and
OCR regions that are being used in the verification point. When you select a mask or
OCR region in the list, it is highlighted in the Baseline and Actual files. This list works
in the same way that the Differences List works, as described in the previous section,
Differences List. The Mask/OCR List part of the Image Comparator is empty if you
do not have any masks or OCR regions defined for the verification point.

The Left, Right, Top, and Bottom columns represent the measurement of the sides of
the mask or OCR region in number of pixels.
