Now, I know nothing about how these things work but it seems to me that a screengrab program must look for some marker which "tells" it where the 'screen' to capture begins and where it ends.
in fact, AFAIK,the screen capture utility works like any monitor, it sees the content of the screen buffer, a memory region where all what have to be displayed by any application is written. It's related to the Xorg server, not any application
And to me, the description of what each of the "Capture Mode" (here: https://docs.kde.org/stable5/en/kdegraphics/spectacle/using.html#idm46336202... ) means may just as well been been written in Aramaic :-).
I challenge that. You are reading this list for so many years I feel you are a friend :-) Spectacle ask Xorg (or kde) where the screen (or windows) buffer is and copy the content. It do not even know it's an image, it's just a bunch of bytes :-). At a second time it write the content as png or jpg file and the problem for browser/text copy is there: spectacle knows nothing about text, so for example enlarging part or the image will give ugly text, reading text meaning have to be done by text recognition package... on the contrary, any Firefox plugin asks *firefox* for the data and so knows if it's image, video, text, whatsoever... jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
