Creating an actual, proper filter plugin

[_Paul_J0hnson_]

Hi guys. I've read through the samples and have a basic filter working like I want it, but now I want to add a GUI to it to allow the user to change some settings and run the filter again.

How on earth do I do this ?

If I put up a modal dialog, then nothing happens until I click OK but then the filter runs and ends. So next I tried *always* returning a small rectangle for DoContinue and then only do stuff once I've pressed the button, but that locks PS up completely - it's like I'm taking all the time and PS won't repaint etc.

Is there an example for this ? Not many real-world filters are going to work without any parameters.

Thanks in advance...

PS. I should mention that this is for Win32 only. There won't be a mac version as it's an internal tool, so any shortcuts on offer here could be useful

Look for the PoorMansTypeTool example in the SDK.

Laughable, I looked in them all except that one assuming it had nothing to do with filters!

Thanks for the tip, off I go...

Plenty of filter source code on my site, http://telegraphics.com.au/sw

See, e.g., "Scramble" for a Filter with a simple UI.

Do all work (GUI/filtering) in filterSelectorStart.
And implement you own preview window (third-party filters can't use image window as preview).

Use filterSelectorParameters only for setting boolean variable
(detecting "Filter again call"/"Plain call")

Ignore filterSelectorContinue, advanceState() callback is superior.
