Actions that support multi-pass verification
The actions that are required to move and copy data are shown in this table.
| Library | Action | Description |
|---|---|---|
| DCO | PropagateToAltText | Copies the character values from AltText[0] to the specified position. |
| DCO | ClearAltText | Clears the character values from the specified position in the field's array. |
To implement a move, do a copy (PropagateToAltText) and then delete the original (ClearAltText).
The action that is used to compare AltText[0] and AltText[1] values is VoteFld.
| Library | Action | Description |
|---|---|---|
| Vote | VoteFld | Sets the confidence level on each character to high and the field status to 0 (OK) if the AltText[0] and AltText[1] values match. Sets the confidence levels to low and the field status to 1 (problem) if the values do not match. |
To implement double blind verification, use the VoteFld action before
the page is displayed to the last operator. If the initial and second
values do not match, the action sets the field status to 1 and the
field is displayed in red.
