Thanks to the donationcoder team I was able to test their screenshot captor tool for free, for which I am grateful.
There is a special and obviously powerful element within the Capture tool collection called "Grab ... scrolling window"
What I missed or was not able to find, as an option, was the possibility to autosave every single window capture (during the automatic scrolling of the scroll window) as independent/single file (see a more detailed description in the post script). The program automatically merges all window captures together so that one "only" is able to save the resulting merged superwindow/image/page. While this is likely very helpful or even desired by other users, I would very much like to be able to have separate files which I would be able to partly delete/merge etc. by my own necessities later on.
In case this is possible already - please let me know how to automatically get single window captures within an automated scroll procedure (pgdown triggered by the screenshot capture program itself).
Alternatively - how much would a donation have to be (Student at the University of Vienna) so to enable somebody to include this program element to the screenshot captor program?
Thanks a heap for any suggestions
P.S: (detailed description of how I conducted the screen captures and where I missed additional save options):
Capture ->Grab windows object or scrolling window -> Ctrl click [on the scroll window of interest]-> Begin a scrolling window capture on this object -> [the Object and scrolling capture tool] menu [appears]:
On the "Vertical Scrolling" I choose: "Scroll by pages" + "Method Simulate Key Presses" + "Stop: Capture until max below" + "maximum scrolls: 50"
-> ok, begin scrolling... -> another [Object and scrolling capture tool] menu appears
Now I am "only" able to save the whole set of screenshots as single, merged file. However, I would prefer to get every of those screenshots as single files (e.g. screensh01, screenshot02, screenshotXX...) so that I would later be able to delete or format to my own likings and have single (manageble) small files rather than large and slow images (often too large for further manipulation) .
