I recently updated some of my plugins to 64 bit. While running some tests on them, I found PSPPX3 will run several of the Topaz plugins (the 32-bit versions) as part of a script without manual intervention when the plugin is triggered in the action. The plugin runs the recorded setting, and the process moves forward until the script is completed.
However, the behavior of DeNoise is different. If you record a PSPP script with DeNoise, using any of the default settings, when the script is run in a batch file it opens the plugin on every image, seeking input selection. The only way I have been able to get DeNoise to run automatically in a batch file script is to do a custom adjustment when recording the DeNoise action and save that adjustment in the plugin. Then the plugin runs automatically, without opening, in the batch file script.
