I am sure I am missing something simple but I've tried everything I can find
I need to convert a rectangle in a NSView to a corresponding rectangle in
screen coordinates.
originally I was using this code:
selected.origin.x = selection.origin.x / ([imageView
frame].size.width/screen.size.width);
selected.origin.y = selection.origin.y / ([imageView
frame].size.height/screen.size.height)+25;
selected.size.height = selection.size.height / ([imageView
frame].size.height/screen.size.height);
selected.size.width = selection.size.width / ([imageView
frame].size.width/screen.size.width);
and it worked. However I have had to change the means by which I was capturing
the screen to CGDisplayCreateImageForRect
I want to select an area in a view that represents the entire screen. I need
that rectangle then to be translated to the correct size and origin in screen
coordinates.
The above code creates a rectangle of the correct size but the origin is so far
off I cannot image how to fix it.
I have tried having the view itself use convertRectToBase passing the screen
bounds. This creates a rectangle of the correct size but the origin is always,
no matter what, 15,183.
I'm totally lost here and don't even know what to search for now that my other
attempts have failed.
Could some one help me out?
I'm hoping to find something with low overhead as clicks are a
factor._______________________________________________
