Dealing with Different Color Depths & Pixel Color

[golfjrr]

How do you deal with users who have say 16 bit color, 32 bit color etc when searching for certain colors since you get different results if they have different color depths. Also is there an easy way to test what color depth mode they are in?

Yes I am an autoit newbie...

According to this topic, beta versions of AutoIt should contain an @DesktopDepth macro that returns the color depth (32, 16, etc).

Download the latest AutoIt beta from here: http://www.autoitscript.com/autoit3/files/unstable/autoit/

(The autoit-v3.0.102.exe installer is probably the easiest to use)

If you don't want to use the new beta you can use one of these quick and dirty scripts.

For win2k

; RegKey to video card used as Video0 which should be main/default video card
$VideoCardTotalKey = RegRead("HKEY_LOCAL_MACHINE\HARDWARE\DeviceMap\Video", "\Device\Video0")
; Set results to an array split by \
$VideoCardTotalKeyArray = StringSplit( $VideoCardTotalKey, '\' )
; Total number of items in the array
$VideoCardTotalKeyArrayNumber = $VideoCardTotalKeyArray[0]
; Only concerned with last two keys.  Pick them up by using array total and array total minus one.
$VidString =  & $VideoCardTotalKeyArray[($VideoCardTotalKeyArrayNumber - 1)] _ 
               "\" & $VideoCardTotalKeyArray[$VideoCardTotalKeyArrayNumber]
; $VideoBits should = color depth in decimal value
$VideoBits = RegRead("HKEY_CURRENT_CONFIG\System\CurrentControlSet\Services\" & $VidString, "DefaultSettings.BitsPerPel")
MsgBox(4096, "Bits", $VideoBits)

For winxp

; RegKey to video card used as Video0 which should be main/default video card
$VideoCardTotalKey = RegRead("HKEY_LOCAL_MACHINE\HARDWARE\DeviceMap\Video", "\Device\Video0")
; Set results to an array split by \
$VideoCardTotalKeyArray = StringSplit( $VideoCardTotalKey, '\' )
; Total number of items in the array
$VideoCardTotalKeyArrayNumber = $VideoCardTotalKeyArray[0]
; Only concerned with last two keys.  Pick them up by using array total and array total minus one.
$VidString =  $VideoCardTotalKeyArray[($VideoCardTotalKeyArrayNumber - 1)] & "\"
; $VideoBits should = color depth in decimal value
$VideoBits = RegRead("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\Control\VIDEO\" & $VidString & '\0000\', "DefaultSettings.BitsPerPel")
MsgBox(4096, "Bits", $VideoBits)

Thank you. I will look into it.

I actually made that suggestion to add Desktopdepth. Someone actually took it, or maybe others suggested it as well..

I would have suspected but couldn't find it, so I asked the question and made the suggestion to add a macro for it. Looks like someone listened to somebody or maybe enough people wanted the feature it's at least made it into the beta.
