I wouldn't think so, The SnagIt canvas area maxes out at 25,000 pixels. So you can't edit it and break it into bite sized pieces. Images slow to a crawl at 25,000 on my computer. "In SnagIt that is" And my computer is no slouch.
I'm a little surprised you can capture such a long scrolling area to be honest. It must be a pain to share and view like that. Or am I mistaken?
Not at all, my computer is pretty robust and apart from the 20-30 second image processing time and slight lags in the editor, it's not so bad. I much prefer having one large picture than working with two and having to take two captures for what should amount to one. Most of my images are >800w,<100kh,
