HBitmap

Hi,
im currently try to implement a fingerprint scanner in a programm. Now one functions returns a hbitmap handle. i know this is a reference to the memoryblock where the image data is. but how can i get this image as a pixmap?

createStaticPixmap needs a byte pointer and i only got the handle as integer.

can anyone help me please, i'm sure this is easy but i dont get it.

	Local handle
	Print hdc
	
	Print GrCapRawImageToHandle(rawImage , width , height , hdc , Varptr handle)
	
	Local pixmap = CreateStaticPixmap(Byte Ptr(handle) , width , height , Width * 3 , PF_BGR888)
	DrawPixmap(pixmap , 0 , 0) 'crash ... system surface failed

If the handle is an integer, turn it into a byte pointer with

Byte Ptr(Handle)

Looks like that's what you're doing.

Are you sure you'd have permission to create a static pixmap pointing to memory outside of BlitzMax's realm?

@Angel.

Errrm, can you explain the
I understand the Phrase ;) I just dont know what you mean by permission. And I wouldnt have the foggyest Idea if I had permission or not. Thou I suppose that if I dont know I cannot have.

@Klass, sorry for thread stealing

@AngelDaniel

as you see i've turn it into a byte pointer during the function call

CreateStaticPixmap(Byte Ptr(handle) , width , height , Width * 3 , PF_BGR888)

i think it got something to do with the hbitmap struct!?
I dont know how to handle such format.
