Acces to pixel data???

Hi there,
How does one get access to pixels in an image?
I looked at the Image module. It has: Load, getDepth, getSize; but no getPixelData!!!
I searched many threads it seem others like to write their own image loaders or use PIL.
Does the Blender Python API provide access to image pixels or not?

Thanks for any help

I needed to get at pixel data for writing a custom heightmap engine. I couldn’t find anything with images in plain python, so I ended up using PIL.
