    Hi !

    I'm completly newbie to photoshop plugin development and I have
    several questions:

    1) I want to know if it's possible to make a plugin that apply some
    blending operation pixel-by-pixel between separate layers of the same
    image (or separate images ?) and output the result into a single
    image.
    2) Can I write this kind of plugin with old versions (5 or 6) of the
    official SDK and run it with latest version of PS (7 or CS) ?
    3) Can I write this kind of plugin with an alternate tool (like
    FilterMeister) ?
    4) Additionnaly if someone can give me url references or samples
    source code as a start point it will be a great help for me...

    Thanks for your reply...
    Marc.

  2. A single filter plug-in cannot do this as filter plug-ins can only
    access the current layer. However some developer have been able to
    accomplish this via a combination of an automation plug-in and a hidden
    filter plug-in that gets is invoked by the automation plug-in once for
    each layer it needs to acces.
    You will need Photoshop 6 or later to accomplish this - that is when
    support for hidden plug-ins like this was added.
    Not sure what that it.

    FilterMeister (http://www.filtermeister.com/) is a very neat tool but
    subject to the same limitations mentioned by Marc (a Filter plugin can
    only access the current layer).
    I am sure Adobe is planning a new plugin API which will allow layer
    access - then it will be straightforward... if you can afford the new
    SDK and pass their background checks.
