GDI help needed

[Noviceatthis]

Hello all,

So basically i'm playing around with GDI plus in an effort to understand it better, and i've hit a bit of a problem:

#include <GDIPlus.au3>

_GDIPlus_Startup()

$hBitmap = _GDIPlus_BitmapCreateFromScan0(500, 80)
$hContext = _GDIPlus_ImageGetGraphicsContext($hBitmap)
_GDIPlus_GraphicsClear($hContext, 0xFFFFFFFF)

$hBrush1 = _GDIPlus_BrushCreateSolid(0xFF8090F0)
$hBrush2 = _GDIPlus_BrushCreateSolid(0xFFCC00FF)


_GDIPlus_GraphicsFillRect($hContext, 0, 0, 250, 80, $hBrush1)
_GDIPlus_GraphicsFillRect($hContext, 250, 0, 250, 80, $hBrush2)


_GDIPlus_ImageSaveToFile($hBitmap, @ScriptDir & "\Test.jpg")

_GDIPlus_BrushDispose($hBrush1)
_GDIPlus_BitmapDispose($hBitmap)
_GDIPlus_GraphicsDispose($hContext)
_GDIPlus_Shutdown()

ShellExecute(@ScriptDir & "\Test.jpg")

So it does what I want, to an extent. The transition zone between the two colours has (if you zoom in) several other intermediary colours. I was just wondering whether it was possible to have the the one colour transitioning to the other without these intermediaries, meaning there are only two colours in this picture.

Thanks in advance.

Replace "jpg" by "bmp"
