GC Image Users' Guide

Operations Journals

GC Image maintains a journal of operations that have been performed. Each entry in the journal includes the name of the operation, the parameters that were used in applying the operation, and all information that is required to undo the operation. The operations journal supports three operations:

View the list of operations.
Undo the most recent operation.
Report the journal.

List Operations

To see a list of the operations performed, select the List Operations option from the Edit menu of the Image Viewer. GC Image presents a popup with a text box listing a brief description for each operation that has been performed on the image. Operations are given in reverse chronological order (i.e., as a stack), with the most recent operation listed first. To close the operations list, click the OK button on the List Operations popup. Figure 1 shows the List Operations popup.

Undo Operation

To undo the most recent operation, click the Undo button or select the Undo option from the Edit menu of the Image Viewer. The last operation that was performed to modify the image will be reversed.

Report Journal

To generate and view a formatted report listing the operations that have been performed on the image, select the List Operations option from the Edit menu of the Image Viewer. Then, click the View Journal button on the List Operations popup. The user is prompted to name the report file and the report is formatted as an XML file and viewed with a web browser. Figure 2 illustrates a journal report.
