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!!!
i did some researchs how to set the font and the only way is to overwrite the subclass with WM_DRAWITEM. With WM_SETFONT i can only change the font for all tab pages, but i want to change the font for a specific page.
So i have to set the $TCS_OWNERDRAWFIXED style to the tab control to send the WM_DRAWITEM message to the parent window. When i set this style, i can change the fonts, but sadly the tab looses the nice and simple "AutoIt style". I created two child guis, the first is the owner draw tab and the second the "Normal" tab.
My questions is, how to create this special "AutoIt style"???

I would like to know how to check if a specific font is installed in user's system. If it is not installed, my program needs to install the font. (Don't worry about the copy right of the font. it's free) I have got some points from google which directs me into _WinAPI_AddFontResourceEx function. But help file says that this function is only for current session. And i also got the _WinAPI_EnumFontFamilies function too. But before trying any of these, i would like to hear from the masters.
Hello all! I'm trying to figure out how to display the contents of my Microsoft Outlooks inbox inside of an AutoIt GUI.
Local $oIE = _IECreateEmbedded() $browserObj = GUICtrlCreateObj($oIE, 20, 60, 780, 580) _IENavigate($oIE, "https://outlook.office.com/owa/#path=/mail")
I need help with loading true type fonts(*.ttf), without installing it. (Font: star_jedi.zip)
