I've tried in several cases to use a p.ng file in my program and was unsuccessful.

I would try it with GUICtrlCreatePic() and GUICtrlSetImage and so forth. Everytime I would try to use a .png
it would just put a blank space wherever the image was supposed to be.


does autoit support png's?

PNGs are supported:

GDI+ is the key:

#include <GDIPlus.au3>
#include <WinAPI.au3>
_GDIPlus_Startup()
$image=_GDIPlus_ImageLoadFromFile("image.png")
_GDIPlus_ImageSaveToFile($image,"image.jpg")
_WinAPI_DeleteObject($image)
GUICreate("test",300,300)
GUICtrlCreatePic("image.jpg",10,10)
GUISetState()
Do
    $msg=GUIGetMsg()
Until $msg=-3
_GDIPlus_Shutdown()

So it converts it over to a .jpg?

My image is very deformed in the gui?...

And it lost ALL of its glossiness, and resolution...

I wanted to use .png in the first place so I could have really good looking images.

Change to .bmp

Or you could paint the control yourself

$hwnd = GUICreate("test", 300, 300)
GUICtrlCreatePic("", 10, 10, 280, 280)
GUISetState()
GUIRegisterMsg($WM_PAINT, "_ReDraw")
$graphics = _GDIPlus_GraphicsCreateFromHWND($hwnd)
_GDIPlus_GraphicsDrawImageRect($graphics, $image, 10, 10, 280, 280)

When I use this method whenever I move around my window a blackish border expands around my image and stays there. then i minimize it and it goes a way, but then re-appears when i move my window again...?

Here's the code I am using:

#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <WinAPI.au3>
_GDIPlus_Startup()

$hwnd = GUICreate("", 500, 500)
GUICtrlCreatePic("", 20, 20, 24, 26)
GUISetBkColor(0xeef2fd, $hwnd)
GUISetState()
GUIRegisterMsg($WM_PAINT, "_ReDraw")
$graphics = _GDIPlus_GraphicsCreateFromHWND($hwnd)
_GDIPlus_GraphicsDrawImageRect($graphics, $image, 20, 20, 24, 26)

Do
    $msg = GUIGetMsg()
Until $msg = -3
_WinAPI_DeleteObject($image)
_GDIPlus_GraphicsDispose($graphics)
_GDIPlus_Shutdown()

Func _ReDraw()
    _GDIPlus_GraphicsDrawImageRect($graphics, $image, 20, 20, 24, 26)
    Return $GUI_RUNDEFMSG
EndFunc;==>_ReDraw

When I run it and move the window containing my .png image a black border forms around it. Is is the re-drawing function? I'm lost and also very new with this GDI+ stuff.

[AustrianOak]

Bump. Does anyone need to see a screenshot?

[monoceres]

Try something like:

Plain Text        expandcollapse  popup

#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <WinAPI.au3>
_GDIPlus_Startup()
$image = _GDIPlus_ImageLoadFromFile("glass.png")


$hwnd = GUICreate("", 500, 500)
GUICtrlCreatePic("", 22, 22, 20, 22); Changed here
GUISetBkColor(0xeef2fd, $hwnd) 
GUISetState()
GUIRegisterMsg($WM_PAINT, "_ReDraw")
$graphics = _GDIPlus_GraphicsCreateFromHWND($hwnd)
_GDIPlus_GraphicsDrawImageRect($graphics, $image, 20, 20, 24, 26)

Do
    $msg = GUIGetMsg()
Until $msg = -3
_WinAPI_DeleteObject($image)
_GDIPlus_GraphicsDispose($graphics)
_GDIPlus_Shutdown()

Func _ReDraw()
    _GDIPlus_GraphicsDrawImageRect($graphics, $image, 20, 20, 24, 26)
    Return $GUI_RUNDEFMSG
EndFunc;==>_ReDraw

As far as I can see it looks like its solved, but I don't understand why...

You changed the width and height (24,26) to 20,22. How did that fix it?

Difference by 'GUI Border Width' added, or not.
