???

ImageID = CreateImage(256,256)
Debuglog GetDC(ImageID) ; returns 0 :(

GetDC works okay for windows ect but not on images, am i missing something here?

Purebasic allows this...

CreateImage(1,256,256)
UseImage(1)
OutPut = ImageOutput()
DC = StartDrawing(OutPut)
Debug Str(DC) ; shows the DC for the image
EXTFloodFill_(DC,10,10,Point(10,10),1)
StopDrawing()

Sorry to be a pain, but can this be done in blitz? Thx
