Because the filter takes up a lot of disk space, it is likely that the computer has insufficient memory, so you can't see the picture. If the computer is out of memory: 1. Click Edit-Preferences-Plug-ins -lns and Temporary Disks to open the Preferences page.
2. There are four columns under the temporary disk (see the exclamation point prompt) (1). Do not move the startup disk (2). Do not change it to D (3). Do not change it to E (4). Do not change it to F. Click OK.
The next time the temporary storage disk is full, it will be stored in D/E/F disk one after another.
If the option "Show Image:" is not turned on, the opening method is as follows: 1. Open a picture with pscc2020 software and click the "Filter" menu in the toolbar. 2.
