Hi, I have created a filter plug-in ( just followed the photoshop sdk filters samples ) - it uses ReadScriptParamaters/WriteScriptParameters. Photoshop seems to save my data somewhere (where???) but when I close and then open again photoshop my data have dissappeared - it seems that my data are not saved to the .psd file. Do I do something wrong? I do I put my data to the .psd file?
Some of that is saved in preferences. But, as noted in the SDK, primarily that is used for actions/scripting.
The only time it would be saved with a document is if you used it as a Smart Filter.
