actually i dont think it needs antialiasing. i think its just the shadow of the window when the elipse is over it that is making the bottom right of the elipse look jagged, but i dont know the exstyle to remove the shadow

It's a class-style, so you may use SetClassLong.
In this case, however, it'd better be done before the tooltip window shows.
So, the simplest solution could be just using WinClose:

Code:
WinClose, ahk_class SysShadow

I added this code to the magnifier script, BTW.

Thanks for the suggestions. Let me think about them a while.

Yes, sorry, I can see that now. I've been trying myself, but my biggest problem is that I can't seem to understand how that whole stretchblt thing works. I couldnt find where you allowed hidden windows to be shown in the magnifier script you made.

Code:
#NoEnv
#SingleInstance, Force
SetWinDelay, 1


nZ := 2.6            ; Zoom Factor
nR := 1            ; Rectangle of the Zoomer

CoordMode, Mouse
CoordMode, Pixel



ToolTip, %A_Space%
WinClose, ahk_class SysShadow

WinGet, hWnd, ID, ahk_class tooltips_class32
WinSet, ExStyle, +0x00000020, ahk_id %hWnd%

hDC_SC := DllCall("GetDC", "Uint", 0)
hDC_TT := DllCall("GetDC", "Uint", hWnd)

Loop
{
 
   MouseGetPos, xmouse, ymouse
   DllCall("StretchBlt", "Uint", hDC_TT, "int", 0, "int", 0, "int", nR*2, "int", nR*2, "Uint", hDC_SC, "int", xmouse-nR//nZ, "int", ymouse-nR//nZ, "int", nR//nZ*2, "int", nR//nZ*2, "Uint", 0x00CC0020)
   WinMove, ahk_id %hWnd%,, xmouse-nR, ymouse-nR, nR*2, nR*2
   WinSet, AlwaysOnTop, On, ahk_id %hWnd%

}

F6::
Exit:
DllCall("ReleaseDC", "Uint",    0, "Uint", hDC_SC)
DllCall("ReleaseDC", "Uint", hWnd, "Uint", hDC_TT)
ExitApp


F12::
If nR < 300
{
nR += 35
}
return

F11::
If nR > 1
{
nR -= 35
}
return


All i need this to do extra is show hidden windows (like your magnifier you made does) and disappear, rather than become 1 pixel when minimized the most, and would be grateful if you could help.

Where can I read about how to use Stretchblt or bitblt in ahk? Thank you for your continued help and making such great scripts

I updated the script.
Now can launch multiple instances from the same script.

Please don't. I updated the script after reading your post.

I don't think I understood you here. There is no hidden window in the script.
Would you be more specific about what you have in mind?

They are in MSDN:

Oh! lol. i thought it was there the whole time and i was being dumb.

What i mean by hidden windows, is in the script i just posted, some windows wont show, such as objectdock, the main window of my winamp skin and my msn app, but in your magnifier then it shows these.

And what i mean by not becoming 1 pixel, is that when the following script is run, then the magnifier starts off as 1 pixel and u can increase it to 300 pixels, but id like it to start so as you cannot see it, and then can increase it to 300 pixels and then at any point can decrease it so that you cant see it again, so basically i need it to enter a null loop when you press F11 and the width is 1 pixel, and break from this loop on pressing F12.

Code:
#NoEnv
#SingleInstance, Force
SetWinDelay, 1


nZ := 2.6            ; Zoom Factor
nR := 1            ; Rectangle of the Zoomer

CoordMode, Mouse
CoordMode, Pixel



ToolTip, %A_Space%
WinClose, ahk_class SysShadow

WinGet, hWnd, ID, ahk_class tooltips_class32
WinSet, ExStyle, +0x00000020, ahk_id %hWnd%

hDC_SC := DllCall("GetDC", "Uint", 0)
hDC_TT := DllCall("GetDC", "Uint", hWnd)

loop:
Loop
{
 
   MouseGetPos, xmouse, ymouse
   DllCall("StretchBlt", "Uint", hDC_TT, "int", 0, "int", 0, "int", nR*2, "int", nR*2, "Uint", hDC_SC, "int", xmouse-nR//nZ, "int", ymouse-nR//nZ, "int", nR//nZ*2, "int", nR//nZ*2, "Uint", 0x00CC0020)
   WinMove, ahk_id %hWnd%,, xmouse-nR, ymouse-nR, nR*2, nR*2
   WinSet, AlwaysOnTop, On, ahk_id %hWnd%



}

F6::
Exit:
DllCall("ReleaseDC", "Uint",    0, "Uint", hDC_SC)
DllCall("ReleaseDC", "Uint", hWnd, "Uint", hDC_TT)
ExitApp


F12::
If nR < 300
{
nR += 35
}
return

F11::
If nR > 1
{
nR -= 35
}
return


Hope I've explained myself ok.

Edit: I think it's because you've used BitBlt in your magnifier, and from what I can tell, you're stretching that, so I think BitBlt can "see" these windows, where StretchBlt cant, but so far I cant get the mouse into the centre of the magnifier :/

I guess these windows are also Layered windows.

I suppose this could be done using WinHide/WinShow before/after increasing.
BTW, don't forget to set 'DetectHiddenWindows On'.

It's because of 'CAPTUREBLT' ROP. You can use it with StretchBlt too if the size remains the same, where I believe BitBlt does the job faster, however.

I already explained in this very thread why you can't do both, capturing the Layered windows and centering the mouse over the magnifier.
This was the reason why I made the magnifier out of the capturing region in my magnifier script.

I updated the script to use the function form.
And, I combined Magnifier into it too.

very nice

but the problem is that if you do anything low down on the desktop with the magnifier then it wont be magnified

I added the Color-Inversion option to the Magnifier as it's only 1~2 line addition.
The hotkey for it is ^+Q.

I'm legally blind. I would love to see your magnifier script with the color inversion included in it. I use a product called ZoomText (aisquared.com) but am looking for a simple portable magnifier that will invert color. I see light text, dark background best. Can you post a copy?
