i use Snagit for Mac (Techsmith) to capture screenshots of entire web pages (they call it "scrolling capture") successfully.
on occasion, there are some webpages that do not wanna cooperate. from what i can tell, it's pages that have headers or sidebars that remain in place when the page is scrolled. these elements get captured repeatedly in the one shot - usually duplicating whole sections within the shot.
the only way i've been able to clean it up is to find the duplication & slice it out of the image. it's a pain in the ass for long pages.
at first, i thought it was a Snagit issue. but after downloading & trying multiple other full-page screenshot programs & browser extensions, it happens with all of them - on any browser.
so, i've attempted doing a developer inspection of the code & deleting those sections, or trying to find the scripts that make those areas stay static on the pages, but have been unsuccessful. i've also tried using the QuickNuke extension - but still, no luck.
anybody got any other hacks, ideas, apps, extensions, that can workaround this? thanx!
