Is it possible to force a text control to be antialiased or not (regardless
of the global preference set in the windows control panel) ?

I know for a fact that this kind of application specific setting is supported by Windows. But don't know how to achieve it in AHK.

I couldn't find anything about this in the help file. Perhaps through a windows gdi funcition call or something?

Any ideas?

thanks!

If you know it is supported, why ask if it is possible?

In actual fact, there is no application-specific setting. However, it can be controlled per-font via the fdwQuality parameter of CreateFont when the font is created.

Hi, thanks but I think I need some more help with this.
Not too familiar with dll calls from ahk...

Let's take the below code, for example.
What would be the simplest way to force the text to be antialiased (regardless of the Windows preferences)?

Code:

gui, font, s14 bold, Courier
gui, add, text,, hello world!
gui, show

Code:
Gui, Add, Text, w450 h60 hwndText1 0x201, Anti-Aliased
Gui, Add, Text, w450 h60 hwndText2 0x201, Non Anti-Aliased

nHeight    :=  50
fnWeight   := 700 ; FW_BOLD
fdwCharSet := 0x1 ; DEFAULT_CHARSET
lpszFace := "Courier New"
ANTIALIASED_QUALITY := 0x4
NONANTIALIASED_QUALITY := 0x3


hFont1 := DllCall( "CreateFont", Int,nHeight, Int,0, Int,0, Int,0, UInt,fnWeight, Int,0
,Int,0, Int,0, UInt,fdwCharSet, Int,0, Int,0, Int,ANTIALIASED_QUALITY, Int,0, Str,lpszFace )

hFont2 := DllCall( "CreateFont", Int,nHeight, Int,0, Int,0, Int,0, UInt,fnWeight, Int,0
,Int,0, Int,0, UInt,fdwCharSet, Int,0, Int,0, Int,NONANTIALIASED_QUALITY, Int,0, Str,lpszFace )

SendMessage, 0x30, hFont1, 1,, ahk_id %Text1%
SendMessage, 0x30, hFont2, 1,, ahk_id %Text2%

Gui, Show,, Anti-Alias Demo
