Send merged image to PS extension?

[UltimateWalrus]

Hi,

I would like to create a panel for Photoshop which reads the composite, merged image of the current document, applies some effects to it, and mirrors it within the panel itself in realtime.  Here's a mockup of what I'm trying to do, in essence:

I was wondering if anyone could nudge me in the right direction for creating this extension.  It doesn't matter if I have to write it in Javascript, C++, or Java.  My original thinking was to make a separate Java application that used the Connect SDK on localhost, but after I did, it was only able to update after each brush stroke (instead of during, as I would prefer).  Is this possible using the HTML5 extension SDK and/or Photoshop Scripting and/or C++ plugins?  I'm doing my best to figure it out, but the documentation's all over the place.

Thanks!

Hi UltimateWalrus,

I would use generator to fetch the pixels and write out a .png.

generator-core

This can run from Your html panel, even though it is not the officially supported way.

Then spawn an ImageMagick process which can do a lot of stuff with the pixels:

imagemagick

Convert, Edit, Or Compose Bitmap Images @ ImageMagick

After that, just read back and display the finished image.

Regards,

Oliver
