The control panel has the following buttons:
[Roll Back] : When WV2+ is started, a snapshot of the current history state for the active document (i.e., the target to be watermarked) is saved. If you don't like the results of your watermark, clicking this button will roll back to the unmarked state so you can try again. If you close and re-open the script with the same image active, the original snapshot is not updated.
[Reset Text] and [Reset Image] : these return the values in the respective settings to the defaults defined in the script. Advanced customisation of defaults.
[Tokens] : displays a list of the available tokens and the values for the current image.
[Fonts] : displays a list of the fonts installed on your system. The number of fonts displayed is determined by the preference setting. [Previous] and [Next] buttons can be used to navigate the list. [Save List] stores a copy of the font list in "PostscriptNames.txt" in the default folder. There is a radio button by each font, if you check one and click [Use Font], the Postscript name is automatically copied to the Font setting in the main dialogue.
[Test Text] : this pops a message window showing the meaning of the watermark text pattern you have defined. Values for the current document are used.
[Preferences] : opens the Preference Setting dialogue.
[Help] : display a help screen. There are different sections explaining the use of WV2+.
[Cancel] : closes the script dialogue.
[Open] : opens a previously saved settings file for a watermark.
[Save] : save the current watermark settings to the default file. This must be done to provide input for the batch script. These will also be the setting loaded as the defaults, the next time the script is run;"wm2.settings.txt" is saved in the default folder.
