Not able to call my filter plugin (Hidden.cpp) when there is a group in the document.

[i73]

I have no idea why I the `AutomationFilter` plugin is not triggering the Hidden plugin whenever I have a group folder in the document.

I'm calling my Hidden plugin with: sPSActionControl->Play(&result, hiddenEventID, descriptor.get(), plugInDialogSilent);

and works every time I don't have a group folder in the PS document...

Returning error when trying to Play my plugin (--25920):

Update:

I've since found out that it's a: 'errEventNotAvailableDefine' So is it possible to have a group in the PS doc?! I understand it's looking for the properties of pixels but to not even allow you to run a filter plugin is stupid!

Is there a fix for this?!

Thanks!

Filter plugin works with bitmap. Group has not bitmap. Therefore it can't work.

I understand that, is there a work around I can do to allow me to do this?

[Jarda Bereza]

You need to get data for layers inside folder not folder itself.

The problem is it's not even calling / playing my filter plugin because there is a group folder in the document, The error you see: (--25920) is from me trying to call / play the filter plugin from my Automation Filter. So I haven't even entered into the main of my filter to get any data.

I was thinking the best way would be to flatten my groups and paste them into a new doc, but I don't really like that Idea because it's so slow. Any other work around you can think of?

[Jarda Bereza]

I don't know. I have very little experiences with C++ SDK.

Maybe you could utilize Generator plugin somehow? It can get pixel data for groups.

Thanks for your reply, where could I find the 'Generator' plugin? I can't see it in the sampleCode.

It is not C++ but I don't know why you need so maybe it could fit your needs.

I'd like to re open this to discuss solutions I can do.

I need the filter plugin to work with groups or I need the ability for the groups to contain pixel data so they don't fail, since I need to read the pixel data of a layer. It makes absolutely no sense for a plugin to fail without before any entry point is called.

Not sure what more to tell you. Filters run on pixels.

I would do this, with some really bad code from a language I am creating:

while(true) {

     select that layer

     get the type of layer

     if the type is not pixel then either skip it or rasterize it (Merge Group for your problem)

     run my filter

     is there another layer then keep going

}

[i73]

That's a shame, merging these groups adds a lot of time to the process. Do you have a suggestion for a plugin that can handle both groups and reading pixel data? Or is the Filter plugin the only one I have access to pixels?
