2020/08/16 New Version CropTool.au3 I've made some changes and fixes to this function: I added the possibility to vary both the thickness of the selector and its color. to customize the appearance and behavior of the tool, you can change the values of some variables in the function listing. See comments on lines 140-170 You can also vary the look of the border by setting a custom dash/space length pattern. Thanks to @UEZ for that. See here for reference. Hope it is free of bugs. (i don't know how to test it to see if it is also DPI aware??) Suggestions for improvements and bug reports are welcome. How to use this demo of use: hit Ctrl+PrintScreen to activate the tool LeftClick and drag on the borders of the tool to resize the area you can also Leftclick and drag within the area to move it around RightClick within the area to shot a screenshot of only the delimited area to the clipboard. in short "how to use the function" outside this demo in your programs: including the following 4 standard udf #include <Windowsconstants.au3> #include <WinAPISys.au3> #include <Misc.au3> #include <GDIPlus.au3> and pasting the _Crop function in your listing is all what you need, then: call the _Crop() function; the 'selector' appears around the mouse hovering the mouse over any side or corner the cursor should change accordingly; LeftClick on the edges and drag to redim the area, also LeftClick within the area and drag to move the selection around. When you are done with the selection, RightClick within the area or also hit the ESC key, the 4 element 1D array is returned to the caller and the 'selector' disappears from the screen Thank you ... below original post ... A function that allows you to freely and visually select an area of the screen Yes I know, there are already some in the forum, however here is yet another cropping tool. I collected some snippets from the forum and merged in a simple and quick cropping tool implemented as a single standalone function. The _Crop() function simply returns a 4-element 1D array with the x-y coordinates of the upper left and the width and height of the selected area, respectively in the elements [0] [1] [2] [3]. So it's up to you to make good use of these parameters An example of use: Since Windows already has both a screenprint functionkey to copy the whole screen to the clipboard and the Alt-printscreen shortkut to copy only the active window to the clipboard, I'm goinmg to bind this _crop() function combined with the Control-printscreen hotkey to create a "partial" screenshot of the delimited area of the screen. The captured screenshot of that area is copied to the clipboard, so you can paste it wherever you want. How to use it: after running the script, use the Control+Printscreen keys to activate the crop tool that appears around the mouse position; then use the mouse to visually resize and move the area and when you have delimited the desired area click with the right mouse button inside the area to copy it to the clipboard. Suggestions, improvements and finally error reports are welcome Happy cropping #AutoIt3Wrapper_Res_HiDpi=y #include <Windowsconstants.au3> #include <WinAPISys.au3> #include <Misc.au3> #include <GDIPlus.au3> #include <Clipboard.au3> ; ---------------------- ; -- Demo start -------- ; ---------------------- #include <ScreenCapture.au3> ; needed only For this demo Global $user32 = DllOpen("user32.dll") While 1 ; hit Control+Printscreen to call the _Crop Function If _IsPressed("11", $user32) And _IsPressed("2C", $user32) Then _example() ; 11 CTRL key + 2C PRINTSCREEN key ; hit Control + c to exit this script (can be castomized with other keys) If _IsPressed("11", $user32) And _IsPressed("43", $user32) Then ExitLoop ; 11 CTRL key + 43 C key Sleep(150) WEnd DllClose($user32) TrayTip("Crop demo", "End of the 'TSR' crop demo", 3, 1) ; (1) = Info icon Sleep(3000) Exit Func _example() $aRect = _Crop() ; mark the area If Not @extended Then ; if the ESC key was pressed within the _Crop function the @extended is set to 1 _GDIPlus_Startup() Local $hGui = GUICreate("", $aRect[2], $aRect[3], $aRect[0] - 1, $aRect[1] - 1, $WS_POPUPWINDOW) Local $idPic = GUICtrlCreatePic('', 0, 0, $aRect[2], $aRect[3]) Local $hTimer = TimerInit() Local $hBmp = _ScreenCapture_Capture('', $aRect[0], $aRect[1], $aRect[0] + $aRect[2] - 1, $aRect[1] + $aRect[3] - 1, False) Local $hBitmap = _GDIPlus_BitmapCreateFromHBITMAP($hBmp) Local $iMidX = $aRect[0] + $aRect[2] / 2 Local $iMidY = $aRect[1] + $aRect[3] / 2 ; snippet by UEZ ; https://www.autoitscript.com/forum/topic/129333-screen-capture-to-clipboard/?do=findComment&comment=898287 Local $bResult = _ClipBoard_Open(0) + _ClipBoard_Empty() + Not _ClipBoard_SetDataEx($hBmp, $CF_BITMAP) _ClipBoard_Close() If $bResult = 2 Then ToolTip("the area was copied to the clipboard", $iMidX, $iMidY, 'Info', 1, 6) Else ToolTip("Something went wrong", $iMidX, $iMidY, 'Error', 3, 6) EndIf ; snippet by Malkey ; https://www.autoitscript.com/forum/topic/191425-capturing-image-without-saving/?do=findComment&comment=1373088 Local $STM_SETIMAGE = 0x0172 GUICtrlSendMsg($idPic, $STM_SETIMAGE, $IMAGE_BITMAP, $hBmp) _WinAPI_DeleteObject($hBmp) GUISetState() DllCall("User32.dll", "int", "AnimateWindow", "hwnd", $hGui, "int", 750, "long", "0x00050002") ; Right-Left GUIDelete($hGui) Sleep(250) ToolTip('') ; #ce ; GUIDelete($hGui) _WinAPI_DeleteObject($hBmp) _GDIPlus_BitmapDispose($hBitmap) _GDIPlus_Shutdown() EndIf EndFunc ;==>_example ; ---------------------- ; -- Demo end ---------- ; ---------------------- ; #FUNCTION# ==================================================================================================================== ; Name ..........: _Crop ; Description ...: A function that allows you to freely and visually select an area of the screen ; Syntax ........: _Crop([$i_X = Default[, $i_Y = Default[, $i_W = Default[, $i_H = Default[, $iMinW = -1[, $iMaxW = -1[, ; $iMinH = -1[, $iMaxH = -1]]]]]]]]) ; ; - To resize the area click the left mouse button and drag on any of the moving colored edges of the tool. ; You can also LeftClick within the selected area and drag to move the whole selection. ; ; - To terminate the selection operation RightClick within the selected area. ; ; You can alse terminate the selection operation by hitting the ESC key; ; in that case the @extended macro will be setted to true ; ; Parameters ....: All parameters are optional: ; $i_X - [optional] an integer value.

UEZ has kindly provided me with code that rotates an image per a line: see here Because I want to trim a photograph after rotation, I need to crop the photo. I wrote code which calls _GDIPlus_GraphicsSetClipRect() to do this, but it places spurious stuff in the corners: see 2.jpg attached. I want only the trimmed photo to show. The original jpeg is also attached. The arguments to _GDIPlus_GraphicsSetClipRect() come from solving 2 simultaneous equations: if a and b are the width and height of the original photo, find x and y, the width and height of the rotated and cropped rectangle; a = x cos(ang) + y sin(ang) b = x sin(ang) + y cos(ang) My solution is: x = (b * sin(ang) - a*cos(ang)) / (sin(ang)^2 - (cos(ang)^2) y = (b * cos(ang) - a * sin(ang)) / (cos(ang)^2 - sin(ang)^2) To try to get a handle on the problem, I have temporarily added in several lines in Case $btn. In 2.jpg, you can see that the rectangle bounding the area to be retained is in the wrong place.

This is my attempt on loading and let the user select only a portion of an image. I found some samples by Melba23 and UEZ and tried to glue things together. I think I've almost done it but still have some problems: Resizing and displaying image is not always proportional (just try the script with different resolution images, expecially big ones) The rectangle selection to crop is wrong: it actually selects a different region of the screen Function _GUICtrlStatic_SetImage does not work.

Hi there.. I want to work on a image review tool. The basic idea of this tool is to review some GUI applications (developed in any language) and give comments to the developer with reference to the part of the GUI, I am making comment on. The final report with comments needs to be in MS Excel. My idea is first run the application under review and get the GUI. Then using AutoIT place a transperant layer over it (could be on whole of the desktop size also) then mark a rectangle with a cross mouse icon on interested area, get the image of that area from the GUI beneath the transparent layer. After that get a text box or something where I can put down my comment about the croped area. Finally save those comments and croped images in excel file. My questions are: 1. Is it possible to get a transparent layer over the GUI using Autoit? 2. Where to find some examples to start with? 3. How do I get the marked image from the desktop? Thanks in advance
