Enable or Disable Anti-Aliasing for your Client PC

You can use the Enable Anti-Aliasing check box (on the Mimics tab of the Options window) to define whether your client PC is able to use the Anti-Aliasing feature on Mimics. If the Enable Anti-Aliasing check box is selected, your client PC can support Anti-Aliasing and so any Mimics that have Anti-Aliasing enabled will have objects with ‘smoothed’ edges. If the Enable Anti-Aliasing check box is clear, your client PC will not be able to use Anti-Aliasing, even if you use it to display Mimics that have Anti-Aliasing enabled.

Anti-Aliasing is performed by your client PC and requires an adequately powered graphics card. If your client PC’s graphics card is insufficient, the anti-aliasing feature can cause slower performance. For this reason, we recommend that the Enable Anti-Aliasing feature is only enabled on client PCs that have adequately powered graphics cards. If your Mimics refresh at a very slow rate or are very complex with a high number of objects and curved shapes and lines, we recommend that you disable the anti-aliasing feature.

If you wish to use Anti-Aliasing but are experiencing slower performance, you should consider upgrading the graphics card in your PC (or upgrade your laptop) and the processors in your PC. Computers using minimum or low specification processors may exhibit slow Mimic refresh rates even when an adequately powered graphics card is in use. Typically, you would only experience slow Mimic refresh rates on lower specification, budget PCs.

To enable or disable Anti-Aliasing for every Mimic that is to be displayed on your client PC:

1. Display the Options window (see Display the Options Window in the ClearSCADA Guide to Client Administration).
2. Select the Mimics tab.
3. Either:
   • Select the Enable Anti-Aliasing check box to activate the Anti-Aliasing feature on your client PC. Your client PC will now apply Anti-Aliasing to any Mimics that are configured to use Anti-Aliasing.

     Or:

   • Clear the Enable Anti-Aliasing check box to disable the Anti-Aliasing feature on your client PC. Any Mimics that you display on your client PC will not use Anti-Aliasing, even if they are configured to have Anti-Aliasing enabled.
4. Select the OK button to confirm your selection and close the Options window.
