AutoHotKey - Resizing Windows - resize

Question

I currently have a HTPC connected to a plasma in my living room, and I've had a few issues with image retention. While browsing the web, etc. for an extended period of time I'll run into the issue. However, it looks like it should be relatively easy to set up a script with AutoHotKey to resize the window automatically on a timer. Could anyone help me get started on a script to accomplish this task? (Also open to any other ideas)
Thanks!

Answer 1

I created a script quite a while ago that "normalizes" windows, i.e. resizes, moves, and performs other actions to make a window confirm to my personal preference.
Whenever a window displays for the first time, it is normalized. If it is closed and re-opened, it is normalized again.
Below is a functioning version of the script and should satisfy the requirements from the original question.
The version I use is much more complicated because it has many more features, e.g. it supports multiple monitors and resizes windows while taking into account the height of the Windows task bar. I use the script to make open/save dialogs bigger (they are too small by default). I also use it to auto-login to some websites and applications.

; Store each unique name in an array.

; Remember the previous window we processed
WindowTitleCleanPrevious := WindowTitleClean
; Only normalize windows that we haven't seen before.
; If we haven't already normalized the window, we do
; the normalize, then set a flag so we don't normalize the same window again.
; Strip out all chars that may be invalid in an AHK variable name.
WindowTitleCleanTemp := StringRemoveAllNonAlphaNum(WindowTitle)
; Variable names can be at most 254 chars, so truncate to less than that.
StringLeft, WindowTitleClean, WindowTitleCleanTemp, 230
; Process the window if:
; (1) It wasn't previously processed (i.e. not in our window-name list named WinList)
; (2) And we aren't sitting on the same window during each loop.
if (WinList%HWND%%WindowTitleClean% != 1 and WindowTitleClean != WindowTitleCleanPrevious)
{
; Get the window's position and size
WinGetPos, WinX, WinY, WinWidth, WinHeight, A
; Is this an MS Word window?

{
; Center the window and resize so it is 80% of the monitor width and 90% of height.

I am working on the same problem. Here is a script that opens and centers the Windows calculator based of your current screen size. I am still figuring everything out, but maybe this will get you started.
;This script opens and centers the calculator on your screen.
#NoTrayIcon
Run, calc.exe
WinWait, Calculator
WinGetPos,,, Width, Height, %WinTitle%
WinMove, %WinTitle%,, (A_ScreenWidth/2)-(Width/2), (A_ScreenHeight/2)-(Height/2)
Return

You can resize and snap the window using the below short cuts.
Windows Key + Left Arrow = Window snaps to left side of the screen
Windows Key + Right Arrow = Window snaps to right side of the screen
Windows Key + Up Arrow = Window snaps to upper side of the screen
Windows Key + Down Arrow = Window snaps to lower side of the screen
Windows Key + Up & Left Arrow = Window snaps to upper left corner of the screen
Windows Key + Up & Right Arrow = Window snaps to upper right corner of the screen
