_GDIPlus_ImageGetWidth&Height problem

[Jex]

#include <GDIPlus.au3>

$hImage = "Autoit.jpg"
_GDIPlus_Startup()
$Width = _GDIPlus_ImageGetWidth($hImage)
$Height = _GDIPlus_ImageGetHeight($hImage)
MsgBox("", "", $Width & "x" & $Height)
GUICreate("Test", $Width, $Height)
GUICtrlCreatePic($hImage, 0, 0, $Width, $Height)
GUISetState()
Sleep(3000)

Not show image size true. Maybe bug? ( I'm using Beta 3.2.9.14 )

$hImage = "Autoit.jpg"

That's not a handle to the image, that's a string.

$sImageFile = "Autoit.jpg"
$hImage = _GDIPlus_ImageLoadFromFile($sImageFile)

Try that.

Hi

It's not a bug that I can see , your not using the _GDIPlus function correctly..

_GDIPlus_ImageGetWidth() and _GDIPlus_ImageGetHeight() work with the handle to an image object not an image file.

You need to load the file as an image object and use the handle of the object.

Cheers

Edit: saunders beat me to it.

Thanks for helps

Edit :

But if im use "_GDIPlus_ImageLoadFromFile($Image)"

"GUICtrlCreatePic" not work.

Example :

That work without "_GDIPlus_ImageLoadFromFile($Image)" :

#include <GDIPlus.au3>

_GDIPlus_Startup()
$Image = "Autoit.jpg"
;$hImage = _GDIPlus_ImageLoadFromFile($Image)
$Width = 500;_GDIPlus_ImageGetWidth($hImage)
$Height = 500;_GDIPlus_ImageGetHeight($hImage)
GUICreate("Test", $Width, $Height)
GUICtrlCreatePic($Image, 0, 0, $Width, $Height)
GUISetState()
Sleep(3000)oÝ÷ Ø­¶­p¢¹0ØjºFåºÂ&j¡§E®W´ß¢&jªºZºÚ"µÍÚ[ÛYH  ÑÑTË]LÉÝÂÑÑT×ÔÝ

Well I must say, that is rather odd. If the image is loaded with the GDI function you are unable to use it with the picture control... hmm, I guess you'll have to dispose it?

Hmm.... yup that works. Give this a try.

#include <GDIPlus.au3>

_GDIPlus_Startup()
$Image = "Autoit.jpg"
$hImage = _GDIPlus_ImageLoadFromFile($Image)
$Width = _GDIPlus_ImageGetWidth($hImage)
$Height = _GDIPlus_ImageGetHeight($hImage)
_GDIPlus_ImageDispose($hImage)
GUICreate("Test", $Width, $Height)
GUICtrlCreatePic("Autoit.jpg", 0, 0, $Width, $Height)
GUISetState()
Sleep(3000)

Not really sure why it won't display the image if you don't release it, but I'm guessing it's an issue with the file already being in use.
