A little stuck with drawing text onto a image (GDI+)

[spyrorocks]

I got this code:

#include <GDIPlus.au3>
_GDIPlus_Startup ()
$hImage = _GDIPlus_BitmapCreateFromFile("template.bmp")
_GDIPlus_GraphicsClear ($hImage)
$iHeight = _GDIPlus_ImageGetHeight($hImage)
$iWidth = _GDIPlus_ImageGetWidth($hImage)

_GDIPlus_GraphicsDrawString ($hImage, "Hello world", 1, 1)

$sCLSID = _GDIPlus_EncodersGetCLSID ("BMP")
_GDIPlus_ImageSaveToFileEx ($hImage, ".\GDIPlus_Image2.bmp", $sCLSID)

_GDIPlus_Shutdown ()

template.bmp is a plain white BMP image. I am wanting to overlay text onto it, then save the finished image.

When I run that code, the samed image doesn't have any text overlayed on it. I am using autoit v3.2.0.10

What am I doing wrong?

Thanks,

In this line

_GDIPlus_GraphicsDrawString ($hImage, "Hello world", 1, 1)

$hImage is a handle for the image but it should be a handle to a graphics object.

There is an example for using _GDIPlus_GraphicsDrawStringEx in

@Program Files\AutoIt3\beta\Examples\GUI\Advanced\Emboss.au3

If you want the background of the pic to show through comment out the _GDIPlus_GraphicsFillRect line.
