You may add a crop function to get only a desired area of the image. 😉

@UEZ, nice. I've fiddled with the UEZ listing a bit you can now rotate the image visually with a slider you can also finely adjust the rotation with two buttons I also added 2 "rulers", one vertical and one horizontal, which you can move by clicking on them and dragging them, in order to have a reference to control the orientation of the image ;Coded by UEZ 2024-03-16 ; [few mods by Gianni :) ] #include <GDIPlus.au3> #include <GUIConstantsEx.au3> #include <WinAPI.au3> #include <WindowsConstants.au3> ; --- rulers ----- Global $iThickness = 4 Global $hGUI1 = GUICreate("", @DesktopWidth, $iThickness, 0, @DesktopHeight / 2, $WS_POPUP, $WS_EX_TOPMOST) GUICtrlCreateLabel("", 0, 0, @DesktopWidth, $iThickness, -1, $GUI_WS_EX_PARENTDRAG) GUISetBkColor(0x00ff00, $hGUI1) WinSetTrans($hGUI1, "", 127) GUISetState(@SW_SHOW, $hGUI1) Global $hGUI2 = GUICreate("", $iThickness, @DesktopHeight, @DesktopWidth / 2, 0, $WS_POPUP, $WS_EX_TOPMOST) GUICtrlCreateLabel("", 0, 0, $iThickness, @DesktopHeight, -1, $GUI_WS_EX_PARENTDRAG) GUISetBkColor(0x00ff00, $hGUI2) WinSetTrans($hGUI2, "", 127) GUISetState(@SW_SHOW, $hGUI2) ; ---------------- Global $sFile = "cover.jpg" ;FileOpenDialog("Select an image", "", "Images (*.jpg;*.png;*.gif;*.bmp)") If @error Then Exit Const $fPI = ACos(-1) _GDIPlus_Startup() Global $hImage = _GDIPlus_ImageLoadFromFile($sFile) Global $aDim = _GDIPlus_ImageGetDimension($hImage) Global Const $hGUI = GUICreate("Image Rotate", $aDim[0], $aDim[1] + 50) Global Const $hDC = _WinAPI_GetDC($hGUI) Global Const $hHBitmap = _WinAPI_CreateCompatibleBitmap($hDC, $aDim[0], $aDim[1]) Global Const $hDC_backbuffer = _WinAPI_CreateCompatibleDC($hDC) Global Const $DC_obj = _WinAPI_SelectObject($hDC_backbuffer, $hHBitmap) Global Const $hCanvas = _GDIPlus_GraphicsCreateFromHDC($hDC_backbuffer) Global Const $hPen = _GDIPlus_PenCreate(0xFFFFFFFF) _GDIPlus_GraphicsSetSmoothingMode($hCanvas, 4) _GDIPlus_GraphicsDrawImageRect($hCanvas, $hImage, 0, 0, $aDim[0], $aDim[1]) Global $hButton1 = GUICtrlCreateButton(' < ', 10, $aDim[1] + 10, 40) Global $Slider = GUICtrlCreateSlider(60, $aDim[1] + 10, 360, 25) GUICtrlSetLimit(-1, 360, 0) ; change min/max value Global $hButton2 = GUICtrlCreateButton(' > ', 430, $aDim[1] + 10, 40) Global $hSlider = GUICtrlGetHandle($Slider) Global $Dummy = GUICtrlCreateDummy() GUIRegisterMsg($WM_HSCROLL, "WM_HVSCROLL") ;horz slider GUISetState(@SW_SHOW, $hGUI) _ImageRefresh() ; Loop until the user exits.

Added the ability to load a custom CSS file where you can change the look of help pages as you would with any html file displaying in Internet Explorer. Also, all external links open in your default browser. This area is to share your CSS coloring or report a problem with the file. Examples of how it could look are: Buuf: Dark: Light ( default ) or just forego all themes and use High Contrast in the OS The general idea is that is your PC. Make it look as you wish The file is in the file downloads area. Replace the v3.3.16.1 CHM with the one in the ZIP along with the CSS file of your choosing to the same folder the CHM is at.

I need from from time to time to run small processes to perform task that would otherwise clog the main process. Yes, there is a number of other UDF that could have done it very well, but I felt they were an over-kill for what I wanted. Don't throw me stones, I know it's not really multi-threading, but it is as close as I could get with simple AutoIt. If someone wonders why I called it PMT, the P stands for Pretending. And I'm also not pretending it is an elaborate UDF. Just small and simple to use... Version 2024-03-24 * corrected bug when 8 parameters (max) is passed to the function Example : #AutoIt3Wrapper_Res_SaveSource=y #include "PMT-UDF.AU3" #include <Constants.au3> _PMT_Init() Local $hProc1 = _PMT_Start("Test1", Default, "Test 1") _PMT_Start("Test2") _PMT_Start("Test3", 5) Local $sResponse While Sleep(50) $sResponse = _PMT_GetResponse($hProc1) If @error Then Exit MsgBox($MB_OK, "Error", "Process has dropped") If $sResponse <> "" Then MsgBox($MB_OK, "Success", $sResponse & @CRLF) ExitLoop EndIf WEnd Func Test1($sTitle, $sMessage) Local $iResp = MsgBox($MB_OK, $sTitle, $sMessage) Return "Done with value " & $iResp EndFunc Func Test2() MsgBox($MB_OK, "2", "Test 2") EndFunc Func Test3($iTimeout) MsgBox($MB_OK, "3", "Test 3", $iTimeout) EndFunc You can pass up to 8 parameters to _PMT_Start. It is up to you to manage the right number. You cannot pass structures, maps or arrays as parameter (only bool, ptr, hWnd, int, float, string, and the keyword Default). You could use my WCD-IPC if need be to exchange large amount of data. If you want to run it compiled, you need to have add #AutoIt3Wrapper_Res_SaveSource=y at the start of your script. In the case you decide to compile your script, _PMT_Init allows you to identity where AutoIt3 is located (in the situation where AutoIt is not installed in the usual directory) to get the right includes in your "threads". Let me know if you have any question, or suggestion, I will be glad to hear them. Enjoy. PMT-UDF.au3

I have also bad tastes at colors, I changed just this striking yellow to #635435 and I am happy with the final result.

tr.yellow,tr.yellowbold { background-color:#808000 /* #ffff9C */ } This is eye hurting but the overall colors are nicely picked. It's a shame that it's not the entire chm theme aware. In dark mode it gives you a feeling of two different applications when you see half of the application in light mode. Anyway, awesome work @argumentum.

Looks nice. I will not use it but I like to learn how such kind of hacks can be done 😉 I'm just curious why this isn't in Examples section of the forum ...
