What "opened plugin"?
What is the ultimate purpose of this and how is your current/intended workflow?
I am trying to create a plugin, that can import SVG files into Photoshop by simply dragging a SVG file into Photoshop. Iike when you're dragging a simple .jpg file inside Photoshop.
Can someone give me an advice here?
Photoshop ships withs several image File Format plugins and I have downloaded two from the web. They have file extensions of 8BI. Have you downloaded Adobe's SDK id may include a sample file format plugin or at least document how to programs on.
I also see this on the web Scand Ltd - SVG Kit 2.0.2 for Adobe® Creative Suite®
On my system they are in the following locations.
C:\Program Files\Adobe\Adobe Photoshop CC 2014\Required\Plug-Ins\File Formats
C:\Photoshop64 Plug-Ins\icon format
