Need a picture in grayscale

[Mojo]

Hi guys,

I'm looking for a way to get a grayscale copy of an image, or even better capture the screen and save it as grayscale bmp or jpg or whatever. Please help!

_GDIPlus_BitmapCloneArea with $GDIP_PXF16GRAYSCALE doesn't seem to work, or does it work with 8 bit images only?

Has anyone ever used those and knows more about it, and can give me some hints?

The piece of code I'm working with is here...

$hBitmap = _ScreenCapture_Capture ("", 0, 0, -1, -1, False)
$hImage = _GDIPlus_BitmapCreateFromHBITMAP ($hBitmap)
$iX = _GDIPlus_ImageGetWidth ($hImage)
$iY = _GDIPlus_ImageGetHeight ($hImage)
$hClone = _GDIPlus_BitmapCloneArea ($hImage, 0, 0, $iX, $iY, $GDIP_PXF16GRAYSCALE)

... $hClone returns 0, meaning that there was an error!

Any ideas how to get this to work? - Please help me - thx!

Have a look at this topic: http://www.autoitscript.com/forum/lofivers...php?t65918.html

It seems that the $GDIP_PXF16GRAYSCALE parameter is to blame. This works fine when the $GDIP_PXF16GRAYSCALE is changed to another value, such as $GDIP_PXF16RGB555. I guess the GDI fails when converting the image type that you have captured to a grayscale format.

This is not the first time someone has has a problem converting something to grayscale:

Thank you for taking some time and posting an answer.

The topic you mentioned is one I created, but since that was some time ago, I summed it up and created a new one, hoping that someone maybe figured it out in the mean time.

Well, we'll see if that's the case
