Perhaps it's something to add to MiniCap, but that would make it closer to the full Screenshot Captor in scope. Come to think of it, it would almost become a MidiCap, somewhere in between.
To make matters worse, although not originally the case (in my request), I've seen reports on the net that transparency with png graphics aren't as straitforward; Any imagery that MidiCap would see on your desktop could be used for webpages.
It seems I can't answer straight. To get back to your question, one of the two lines is the inner loop, and the other line is the outer border loop, where in between transparency gets distributed from 0% to 100%. This is a quick way to add standard masking.
Don't get me wrong, the features in Screenshot Captor are great, including the bitmap masking which is very (very) useful; perhaps it's nice to create a desktop snapshot tool specialized in masking, more graphics oriented, holding the snap collection for a DTP programme.
Hmm, don't know about the coding, but moving a bitmap (or some lines) over a snapshot as a very simple process in MiniCaptor would just do the job. It's late, and I'm working too hard
but that actually makes sense.
I hope other people would approve.
Perhaps MiniCap can map out an image 1:1 if the filename or url of the image is known, but then I'll just stitch images together or use a virtual desktop, this can be solved. Thanks again Mouser.
