I've been using a script in R18 for sometime now and went to use it today in R19 and ran into an error. When I get to this command, GetParameter(c4d.MPBTYPE_DPI), it returns 0.0 which then throws up an error i my script as that measurement can't be zero.
I tried it again in R18 and it works fine. Went back to 19 and it fails to return the dpi.
Is this a known issue?
Texture = c4d.bitmaps.BaseBitmap()
width, height = Texture.GetSize()
mbp = c4d.bitmaps.MultipassBitmap.AllocWrapper(Texture)
dpi = mbp.GetParameter(c4d.MPBTYPE_DPI)
width = width/float(dpi)
height = height/float(dpi)

Hi del, thanks for writing us.
Given that MPBTYPE_DPI is marked as private and accessing the data pointed by this ID is not granted to be valid nor officially allowed, in R19 the default value of 72dpi (which I presume was returned in your execution on R18) is no longer returned. It's instead returned 0.0 or the dpi value set by MultipassBitmap::SetParameter(MPBTYPE_DPI).

What do you mean that it's marked as private? I'm looking at the SDK and I don't see anything that says not to use it. How do we know if we can or can't use things listed in the SDK?
Uses a description ID as a key into the container, and retrieves the stored data.

Hi del, looks like the you've hit an inconsistency in our Python documentation which will be fixed in the future.
I apologize for any inconvenience cause so far, but if you check in the C++ doc (as pointed out in my previous post) you see that it's actually marked as private.
