@error 10 on _GDIPlus_ImageSaveToFile

[Luigi]

Hi, 

I load a png image at $hImage32

$sFile = "C:\Form\default.png"
$hImage32 = _GDIPlus_ImageLoadFromFile($sFile)

This $hImage32 is showed in $hBackbuffer
 

Func _update()
    _GDIPlus_GraphicsClear($hBackbuffer, 0xFFFFFFFF)
    _GDIPlus_GraphicsDrawImageRectRect($hBackbuffer, $hImage32, 0, 0, 32, 32, 0, 0, 32, 32)
    _GDIPlus_GraphicsDrawImageRect($hGraphic, $hBitmap, 0, 0, 32, 32)
EndFunc   ;==>_update

If a error in _update(), ignore... the main question is: I can save the image it is still showed?

Or clear the draw and save?

Whe I call a function to shave $hImage32 the, occur this error:

$TRY = _GDIPlus_ImageSaveToFile($hImage32, $sFile)
_GRID_Save( $hImage32[ 0x02C09480 ] $sFile[ C:\Form\default.png ] $TRY[ False ] @error[ 10 ] @extended[ 7 ] FileExists[ 1 ])

Conform https://msdn.microsoft.com/en-us/library/windows/desktop/ms534175(v=vs.85).aspx

The @error 10 is FileNotFound

The @extended I cant found... (yet)

Someone can help-me to fix this error?

Br, Luigi

It's possible that the folder in root drive needs admin permissions.

You can easily test this by adding #RequireAdmin to your script.

I'm pretty sure that _GDIPlus_ImageLoadFromFile keeps the file open until the image is released with _GDIPlus_ImageDispose. That's the reason for the error.

@LarsJ, you write, I clone the $hImage32 to other handle, and use ImageDispopose, ImageSave and ImageLoad again... It's odd, but work.

Thank you!

It's not odd because as long as the image is loaded and not disposed the image is locked by gdiplus!

Theoretically it should work when you load the file as binary string using:

_GDIPlus_BitmapCreateFromMemory(Binary(FileRead($sFile))

I didn't check it yet...

I will check later, thanks UEZ.
