I searched for years a similar tool, is not a desktop screencaster video recorder and not a screengrabber but something in between
I explain better i need to record my workflow on graphic SW (as gimp,inkscape..) but i need that the screegrab is done only when there are changes in the image window.
in other words this is what i will need
1 i open gimp (or photoshop or...) and i open a image windows
2 now i take a shoot of the window,save, but, here the point,
now i can check a new option "Monitor this windows"
3 "Monitor this windows" simply automatically take another shoots when N pixels change inside that windows
as example suppose i'm drawing, when N, let's say five pixel are changed it automatically take a
new shoot and save in the same directory of the first shoot
3 bis i make a example of a chang of 5 pixel, but should be 5 "or more".
If changes happen toghether (to clear if instead then drawing i apply a filter) then a new shoot has to be taken, doesn't matter if was not a change of 5 but of much more pixel
I think purpose and utility is clear, i have no idea if could be done easily but it would be wonderful if possible
I'm not a native english so if i was not clear just tell me i will try to explain better
Anyway compliment for this sw is the most complete screenshoot utility i found till now and i tried tons of them
Even expensive commercial ones (i never buy one, but i tested the trial versions ) are so complete and full of features
