Adobe photoshop is raster based (bitmaps - slicing a pixel into bits),
but SCIPro picEditor is based on vector mapping (x,y coordinates - mathematic objects) - this is for a couple reasons:
1) tighter file size compression when compiling lines of code versus image compression.
2) SCI can define complex actions based on x,y mapping (IE - ego is in front of x,y but not behind x2,y2)
While photoshop has the awesome ability to work in multiple layers (which can contain several unique effects and manipulation, then blend seemlessly with final image), SCI wouldn't have any way of defining parameters based on Adobe layer attributes.... These two programs simply can't "talk" to each other....
More than likely similar to having Adobe Illustrator "talk" to Photoshop. You can't work on a bitmap in Illustrator unless it's physically textured or mapped onto a specific object that's pre-defined as a vector. Likewise, you can import vector objects from Illustrator into Photoshop, but you can't manipulate masking and effects techniques on the vector objects that are imported.
Kindof a bummer, but maybe this wouldn't be the case with the upcoming VGA version, since this would include complex gradient and shading techniques that more than likely require layering effects?
