Hey all,
Can't find this in the docs. Using FxPlug. Rendering in software, not
hardware.
So I'm retrieving the data pointer from an FxBitmap using the dataPtr
method.
FCP seems to return a pointer to a scanline that represents the top scanline
of pixels and Motion returns a pointer to a scanline that is the bottom
scanline of the image. Increasing by rowbytes gives me the next scanline
(either above or below a, as appropriate)
Can the two teams FxPlug people confirm this? (Darrin? Paul?)
Now that we are drawing into the image some geometry, the information as to
where the dataPtr points is very important. If I missed this in the docs,
can someone point me to where that might be?
Pete
