how to see what lies behind a window? (magnifier problem)

[Gianni]

I'm again on a script that simulates a lens on the screen, >here my previous effort that works quite well but only in one mode, that is: it magnifies the area around the mouse while you move it and it shows the zoomed area into the "lens" window that stays somewhere on the screen.

In the new mode that I would like to achieve, should be magnifyed the area that lies behind the "lens" window and when you move that window it should magnify what's behind it.
Unfortunately here arises the problem, the magnifier magnifies itself recursively, (because it capture the surface of the "lens" itself and not what's behind) with the unwanted result of a zoom area that seems empty.

To see the unwanted effect, just change the value of the variable $bFollowMouse from True to False anf then move the "magnifier" window around.

(the problem is that the function _ScreenCapture_Capture() should be able to capture behind a window)

(I wish the function _ScreenCapture_Capture() where able to capture behind a window)

My question is:
Is there a way to read the content that lies behind the "lens" window? (hopefully avoiding ways like turn off the "lens" windows, make the SnapShot of what's behind, and turn on the "lens" window again, that should result in an ugly flickering effect)

any advise is welcome,
thanks

[JohnOne]

the problem is that the function _ScreenCapture_Capture() should be able to capture behind a window

 

 

Is that documented somewhere?

[Exit]

Why not use standard MS magnify.exe?

In Aero design mode press Cntl+Alt+L for lens mode and Ctrl+Alt+D for dock mode.

[Gianni]

no, that is not a statement, it's what I wish it where

sorry for my  grammar....

did not even know of its existence (nice)

anyway I would like to have my own self made magnifier (both for educational purposes that for use in custom contexts)

[JohnOne]

Might be worth taking a look at >magnifier functions.

[Gianni]

Might be worth taking a look at >magnifier functions.

I agree

thanks for that link

I will have look....

[UEZ]

I solved the problem by moving off the mag. screen to the opposite corner when the mouse nears to the window.

thanks UEZ,

I think you are referring to solve the problem that arises when the mouse overlays the magnifier window. Thanks for the advise, but this is not what I'm trying to solve.

the problem that I'm referring here arises when the function is used in mode "zoom what's behind the magnifier window" (not easy for me to explains exactly).

In short:

Mode 1) : If you run the script as is, it runs in a way that magnifies the area around the mouse and the zoomed area is displayed in the magnifi window.

Wherever is mooved the mouse, what's around the mouse is shown zoomed in the magnifi window. (this is ok for now)

Mode 2) : To activate this mode, change the value of the variable $bFollowMouse from True to False prior of the running of the script.

This mode should zoom the area that is directly behind the magnifi window (and not the area that is around the mouse as in previous mode) so that if you want zoom a zone, you have to move the magnifi windows directly over that zone (in the same way you do when you use a real glass magnifier). The zoomed zone should be shown within the magnifi window while this window is moved around)

Unfortunately this mode do not work, for the reason I've try to explain in first post.

I'm afraid that mode 2 it's not an easy task to achieve (at least for me)

Thanks

[UEZ]

Ok, I think I understood. 

To get the effect work you have to disable aero.

I implemented the aero effect for WinXP by using the effect to get the screen behind a window. Have a look here: '?do=embed' frameborder='0' data-embedContent>>

 

I hope it helps you.
