Lets say I have an application that isn't full screen however I would like to only display that program on the screen and nothing else. Imagine taking a screenshot of a program and then stretching that image to cover the entire screen losing its aspect ratio...
That's exactly what I want to do but live! I need a program that allows you to select rectangular region on the screen and then have that region stretched across the whole screen without any interferences kinda like the windows magnifier how it zooms into the screen but I don't want any interferences and I don't want it to keep the aspect ratio. I also want to mouse locked to this rectangular region of the screen that you select.
The reason is because I want to run symbOS (an 8 bit operating system) full screen with winape. Winape leaves awful black bars on the tops and bottom of the screen when you run it full screen and also has issues with keeping the mouse in symbOS. Even if you run it in a window it has those awful black bars within the window and only does this when you are running winape. Changing the resolution of the host computer does not change the size of the black bars in any way.
So, how can I get this working full screen? Any program I can use to zoom or crop the screen live for me while holding the mouse pointer in the view of the screen?
