I'm trying to write a script in AutoIT but, I have issue in DPI. I'm basically a Lead Software Developer and I use AutoIT from time to time. I have an ERP Launcher that should work on all machines starting by Windows 7, Windows 8.x , Windows 10, Windows Server 2003/2008/2012.
When I was searching in AutoIT forum, I could see previously this " Writing DPI Awareness App - workaround" in the signature of Mr. @mLipok,, but clicking on the link, => page not found.
Do you have any new link or something that you can share with me ? I'm using macbook pro with retina display and VMware machines: Windows 10 and Server 2012 as development machines, but both of them they have 200% scaling and they have AutoIT installed. In this case, when I use Koda (blurry font for sure), I have the controls as I want, and application is working fine, but also blurry font, until it is used on 96 DPI machine.
Now, in windows 10, with DPI System Enhanced feature in the compatibility tab, the application running on 200% scaling is excellent visual like it's running on 96 DPI without touching my code and without doing anything, but no all clients they have windows 10. It seems Microsoft worked a lot on the new feature. But for other machines like windows 7/8/2012, the font is blurry if the clients have scaling above 100% (more than 96 DPI). I know how to enable hidpi stuff in the wrapper and I know how to write the code to use a scaling factor that can be multiplied by every coordinate, but this way is cumbersome and I have to change all coordinates of all X, Y, Width, Height after getting the code from Koda. Is there a fast way ?
So, what do you recommend me guys ?
Been struggling with this one for a while.
when I do a _screencapture_capture call on a high resolution monitor (like my surface book) it gives me an image that has 2 problems:
1. its in the wrong location on the screen
2. it gives me a picture that is larger than the area of the screen I selected, though it only has the content of what I selected.
I was able to easily fix problem #1 by manually adjusting the x y coordinates to compensate for the amount of DPI scale I have.
for instance if I'm 200% zoomed in the code looks like this:
Local $bmp = _ScreenCapture_Capture("", $iX1*2, $iY1*2, $iX2*2, $iY2*2, false) it's problem #2 that is the big problem. I'd like to attach a screen shot of what I'm talking about (see capture.png)
Now I basically understand why this is happening. ScreenCapture grabs each pixel of the screen. This screen, being a high resolution, when its zoomed in adds up several pixels to make one on the screen.
This is a problem for me because I'm taking images of the screen and later looking for those exact images on the screen. if everything is blown up by an indeterminate amount (in my case 2x) then those images can't be found later on.
Does anyone know what I can do?
I tried resizing the images back down to no avail.
_GDIPlus_ImageResize and _GDIPlus_ImageScale don't work because they don't compress the pixels correctly. quality is lost. and the exact image isn't preserved, so I can't search for it later. (see capture1.png)
Anyway, I'm about to give up, been on this problem for too long! does anyone know what I can do? Seems to me that the ideal solution would be to eventually have autoit add an argument to _screencapture_capture that lets you specify a DPI scale amount or something. that can be pulled from the registry at HKEY_CURRENT_USER\control panel\desktop\windowmetrics\appliedDPI.
But in the meantime, does anyone have any suggestions for how I can make my program compatible with 4k resolution monitors? I either need to take the screen capture like normal, then scale it down appropriately without losing quality, or I need to capture the screen in the first place like the human sees it. But I don't know how to do that either.
I'll post my relevant code here: (in my project I call ScreenCapture_DPI_Aware)
#include <Security.au3> Func _GetAppliedDPI() Local $aArrayOfData = _Security__LookupAccountName(@UserName) If IsArray($aArrayOfData) Then ;msgbox(64, "SID String = ", $aArrayOfData & @CRLF) ;msgbox(64, "Domain name = ", $aArrayOfData & @CRLF) ;msgbox(64, "SID type = ", _Security__SidTypeStr($aArrayOfData) & @CRLF) ;Local $AppliedDPI = RegRead("HKEY_USERS\" & $aArrayOfData & "\Control Panel\Desktop\WindowMetrics", "AppliedDPI") Local $AppliedDPI = RegRead("HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics", "AppliedDPI") return $AppliedDPI EndIf EndFunc Func GetScale() $applied = _GetAppliedDPI() if $applied == "" then return 1 else return $applied / 96 EndIf EndFunc Func ScreenCapture_Capture_DPI_Aware($sBMP_Path, $iX1, $iY1, $iX2, $iY2, $bool) $R = GetScale() ;Raito Local $bmp = _ScreenCapture_Capture($sBMP_Path, $iX1*$R, $iY1*$R, $iX2*$R, $iY2*$R, $bool) ;Scaling didn't work: ;_ScaleImage($bmp, $sBMP_Path, abs($iX2 - $iX1), abs($iY2 - $iY1), $R) ;return _ScreenCapture_Capture($sBMP_Path, $iX1*$R, $iY1*$R, $iX2*$R, $iY2*$R, $bool) EndFunc ;Func _ScaleImage($bmp, $outimage, $w, $h, $scale) ; _GDIPlus_Startup() ;Get the encoder of to save the resized image in the format you want. ; Local $Ext = StringUpper(StringMid($outimage, StringInStr($outimage, ".", 0, -1) + 1)) ; $CLSID = _GDIPlus_EncodersGetCLSID($Ext) ; code found here : https://www.autoitscript.com/autoit3/docs/libfunctions/_GDIPlus_ImageSaveToStream.htm ; Local $sImgCLSID = _GDIPlus_EncodersGetCLSID("png") ;create CLSID for a JPG image file type ; Local $tGUID = _WinAPI_GUIDFromString($sImgCLSID) ;convert CLSID GUID to binary form and returns $tagGUID structure ; Local $tParams = _GDIPlus_ParamInit(1) ;initialize an encoder parameter list and return $tagGDIPENCODERPARAMS structure ; Local $tData = DllStructCreate("int Quality") ;create struct to set JPG quality setting ; DllStructSetData($tData, "Quality", 100) ;quality 0-100 (0: lowest, 100: highest) ; Local $pData = DllStructGetPtr($tData) ;get pointer from quality struct ; _GDIPlus_ParamAdd($tParams, $GDIP_EPGQUALITY, 1, $GDIP_EPTLONG, $pData) ;add a value to an encoder parameter list ; Local $gbmp = _GDIPlus_BitmapCreateFromHBITMAP($bmp) ; _WinAPI_DeleteObject($bmp) ; Local $gsbmp = _GDIPlus_ImageResize($gbmp, $w * $scale, $h * $scale) ;Local $ext = _GDIPlus_EncodersGetCLSID("PNG") ; _GDIPlus_ImageSaveToFileEx($gsbmp, $outimage, $sImgCLSID) ; _GDIPlus_BitmapDispose($gbmp) ; _GDIPlus_BitmapDispose($gsbmp) ; _GDIPlus_Shutdown() ;EndFunc
Thanks for any help you can give me!!!
