on mac the handle points to a gworld ptr... from there you'll need to
get the base address which refers to the actual pixmap data. i have
a wrapper for gworld access on mac, and i can post it to my blog next
week sometime (moved this last weekend, have to find a place to put
the peanut butter before i setup the computer).

Is there a way to manipulate/access the individual pixels of a
Picture using the Handle property?
I would like to access the raw picture data with a MemoryBlock, but
I don't know how to convert the pointer returned from the
Graphics.Handle into a MemoryBlock.
Dim g As Graphics = p.Graphics // assume p is passed as
function parameter
Dim m As MemoryBlock
#If TargetWindows
?? = g.Handle(HandleTypeHDC)
#Elseif TargetMacOS
?? = g.Handle(HandleTypeCGrafPtr)
#Endif // Linux not supported
What can I do to get the Handle into a MemoryBlock?
