how can I fit the image when the GUI is maximized? I would like to always measure the 50% height and width of the GUI and is always in the bottom right poistion, and does not lose its quality.

THX

Not sure I understand. Do you want the image to be drawn to fit the GUI window or do you want the image to be drawn starting at the exact midpoint of the GUI (width and height)? Making it be drawn in the bottom right corner of the GUI.

Here's how you would do it if you want the image to fit the width and height of the window

#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <GDIPlus.au3>
#include <Array.au3>
#include <WinAPI.au3>

Global Const $SIZE_RESTORED = 0
Global Const $SIZE_MAXIMIZED = 2

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 615, 437, 192, 124, BitOR($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_TABSTOP, $WS_SIZEBOX))

_GDIPlus_Startup()
$hImage = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\img.jpg")
$hGraphics = _GDIPlus_GraphicsCreateFromHWND($Form1)
Global $resimg = _GDIPlus_ImageResize($hImage, 615, 437)
_GDIPlus_GraphicsDrawImage($hGraphics, $resimg, 0, 0)

GUIRegisterMsg($WM_PAINT, MY_WM_PAINT)
GUIRegisterMsg($WM_SIZE, WM_SIZE)

GUISetState(@SW_SHOW, $Form1)


#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func MY_WM_PAINT($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam, $lParam
    _GDIPlus_GraphicsDrawImage($hGraphics, $resimg, 0, 0)
    _WinAPI_RedrawWindow($Form1, 0, 0, $RDW_VALIDATE)
    Return $GUI_RUNDEFMSG
EndFunc   ;==>MY_WM_PAINT

Func WM_SIZE($hWndFrom, $iMsg, $wParam, $lParam)
    Local $iLoWord = _WinAPI_LoWord($lParam) ; Width
    Local $iHiWord = _WinAPI_HiWord($lParam) ; Height

    Switch ($hWndFrom)
        Case $Form1
            Switch ($wParam)
                Case $SIZE_RESTORED, $SIZE_MAXIMIZED
                    ; The old graphic is based off the size of the old size, destroy it
                    _GDIPlus_GraphicsDispose($hGraphics)
                    ; And recreate it with the size of the new size
                    $hGraphics = _GDIPlus_GraphicsCreateFromHWND($Form1)
                    ; resize the image to the new width/height
                    $resimg = _GDIPlus_ImageResize($hImage, $iLoWord, $iHiWord)
                    ; Implicitly calls MY_WM_PAINT after this, based on the order of window messages received from Windows
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_SIZE

And here's how you could draw it in the bottom right quadrant of the GUI

#include <GUIConstantsEx.au3>

$Form1 = GUICreate("Form1", $iWidth, $iHeight, 192, 124, BitOR($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_TABSTOP, $WS_SIZEBOX))

_GDIPlus_Startup()
$hImage = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\img.jpg")
$hGraphics = _GDIPlus_GraphicsCreateFromHWND($Form1)
Global $resimg = _GDIPlus_ImageResize($hImage, $iWidth / 2, $iHeight / 2)
_GDIPlus_GraphicsDrawImage($hGraphics, $resimg, 0, 0)

GUIRegisterMsg($WM_PAINT, MY_WM_PAINT)
GUIRegisterMsg($WM_SIZE, WM_SIZE)

GUISetState(@SW_SHOW, $Form1)


#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func MY_WM_PAINT($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg, $wParam, $lParam
    _GDIPlus_GraphicsDrawImage($hGraphics, $resimg, $iWidth / 2, $iHeight / 2)
    _WinAPI_RedrawWindow($Form1, 0, 0, $RDW_VALIDATE)
    Return $GUI_RUNDEFMSG
EndFunc   ;==>MY_WM_PAINT

    Local $iLoWord = _WinAPI_LoWord($lParam) ; Width
    Local $iHiWord = _WinAPI_HiWord($lParam) ; Height

    Switch ($hWndFrom)
        Case $Form1
            Switch ($wParam)
                Case $SIZE_RESTORED, $SIZE_MAXIMIZED
                    $iWidth = $iLoWord

                    ; Implicitly calls MY_WM_PAINT after this, based on the order of window messages received from Windows
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_SIZE

Thx, me cupla I try to explain you.

usually I use GUICtrlSetResizing to have a responsive gui... but with the object PIC the image does not maintain a good quality. Now I'm trying with GDI.

Wait, don't leave yet. Gimme a few minutes and I'll create one better that will be a little less graphics intensive and get rid of that flashing. (Been a while since I've done some GDI+ stuff so I gotta remember how I did this lol)

This should do it. Won't redraw and refresh while it's being sized but it will be updated after you release the size box and will be updated upon Maximize/restore. Gets rid of the flashing

Been a long time since I've draw graphics in memory, not directly on the HWND, and then set an image from memory. So I had to remember the order of the bitmaps/graphics lol

Idk what your project entails but maybe you might want a complex GDI+ intensive project to look at to see how you can manage objects. I started this a long time ago, before I left for basic, and never finished it. It was going to be a puzzle style game. I finished the menu portion of it but never finished the puzzle part of it. I used a lot of structs to hold all of my GDI+ objects, windows, etc. As well as using array of string with the function calls to manage the structs (Why have 20 lines to destroy my GDI+ objects when I could have 1 for loop going through and calling the function needed for the struct specified). It's pretty cool though. Creating a context menu (right click) on the GUI and the options displayed are specific to the image you're over (or no image if you're not over one).

No problemo. I've only ever shown that to one other person but I'm sure anyone who finds it might find it useful.

One cool thing I'd like to point out (it's not in the script because I never made it an option) is it will support just Vertical scrolling and just Horizontal scrolling. If you go down to line 306

SetWorkspaceStruct($tWorkspaceMenu, $tControlMenu, BitOR($SCROLL_VSCROLL, $SCROLL_HSCROLL), 3, 1.0, False)

At the moment the menu will scroll left/right and up/down (Ctrl + Mouse wheel will go left/right). If you change this line to this

SetWorkspaceStruct($tWorkspaceMenu, $tControlMenu, $SCROLL_HSCROLL, 3, 1.0, False)

It will make all of the picture fit vertically and only scroll left/right. The opposite is the same for

SetWorkspaceStruct($tWorkspaceMenu, $tControlMenu, $SCROLL_VSCROLL, 3, 1.0, False)

So it will fit all of the images horizontally and then scroll up/down

Alt + Mouse wheel will zoom in/out. Resizing the menu and making all of the pieces bigger/smaller (Just takes a minute because it's going to resize all of the large images to fit the menu again). There's a lot to go through. I know I didn't comment a lot of things. I planned on finishing it and releasing it but real life got in the way and never had the time go dig through it again.

      Just press the lmb and move your mouse. When lmb is released you can adjust the size of the window by dragging the white rectangle to any direction. Rmb will move the marked area.
      Press ESC to get the coordinates of the marked region.
      If you have any improvements, please post it here.
       
      Tested on Win10 x64 only.

      I was looking around the help file and I came across _GDIPlus_GraphicsDrawRect and _WinAPI_DrawLine and I seem to be having the same "problem" where every time it draws into a window and you lose or gain focus it has to redraw itself. Is there anyway around this?

      I have a situation where I am repeatedly capturing a region of the screen and feeding it into Tesseract OCR.  Since the OCR is a relatively slow operation, I would like to create an in memory cache of the ocr results.  An ideal hash key for this cache would be a checksum of the captured image.  With this I could capture the region, checksum it, and then only if I don't get a cache hit I would write the image out to disk for external OCR.
      Now I know I can do this by saving the captured image out to disk, and then summing the disk file with _Crypt_HashFile().  But that's still slower than I would like, and it shouldn't be necessary.  Ideally, it should be possible to checksum the image data directly in memory so I don't have to go to disk at all.  In order to do that, I need a way to dump a representation of the image into a string  (or some equivalent).  Then I could use the _Crypt_HashData() function against that string to create my cache hash key.
      Googling around I found an article here that shows a way to convert an image object to a byte array using System.Drawing.  This was the closest thing I found to what I'm trying to do.  I don't know if that method could be used from within AutoIT, or if perhaps there may be a better way I don't know about.  If someone could give me a shove in the right direction it would be a big help.  Thanks!
