NSBitmapImageRep#bitmapData returns empty String

[emil@…]

after allocating an NSBitmapImageRep with

@nsBitmapImageRepObj = NSBitmapImageRep.alloc.initWithBitmapDataPlanes nil,
                    pixelsWide:200,
                    pixelsHigh:200,
                    bitsPerSample:8,
                    samplesPerPixel:3,
                    hasAlpha:false,
                    isPlanar:false,
                    colorSpaceName:"NSCalibratedRGBColorSpace",
                    bytesPerRow:0,
                    bitsPerPixel:0

@nsBitmapImageRepObj.bitmapData returns an empty String, with size zero.

Unfortunately there is little we can do here. -bitmapData returns a "unsigned char *" type and MacRuby assumes this is a string. However, since the first byte is null, the resulted string object is empty.

There are other ways of getting the data. -getPixel:atX:y: for example might work better.

I am leaving this bug open in the idea that we might find a solution for the -bitmapData problem.
