GDI+ edit file w/o GUI

[Vort3x]

Hey guys ! =)

I have a little question. I'm pretty good in Autoit I guess but I haven't worked with GDI+ for quite some time and I can't get it to work.

I have a simple script without a GUI. In the script directory I habe a file, let's call it "test.bmp".

Now upon execution I want the script draw something (a rect or a line or whatever) into "test.bmp" without opening any windows. Its this possible?

#include <GDIPlus.au3>

$file = @ScriptDir&"\test.bmp"

_GDIPlus_Startup()

;What do I have to add here?

_GDIPlus_GraphicsDrawLine(hGraphic, 10, 10, 50, 50) ;<- how do I make my file the hGraphic?

_GDIPlus_Shutdown()

Exit

Thank you so much for any help!

Take a look at _GDIPlus_ImageGetGraphicsContext.

like this

#include <GDIPlus.au3>

$file = @ScriptDir&"tc4.jpg"

_GDIPlus_Startup()

$hImage = _GDIPlus_ImageLoadFromFile($file)
If @error Then Exit 1
$hGfx = _GDIPlus_ImageGetGraphicsContext($hImage)
If @error Then Exit 2
$aRet = _GDIPlus_GraphicsDrawString($hGfx, "Hello world", 140, 110)
If Not $aRet Then Exit 3
$fSave = _GDIPlus_ImageSaveToFile($hImage, @ScriptDir&"returned.bmp")
If Not $fSave Then Exit 4
_GDIPlus_Shutdown()

Exit
