While I should be able to use:

bytesPerRow:(NSInteger)rowBytesbitsPerPixel:(NSInteger)pixelBits
and pass in the appropriate values from my PixMapHandle, I was
hoping that
PixMapHandle previewPixMap = GetGWorldPixMap( previewGWorld );
LockPixels( previewPixMap );
[NSBitmapImageRep imageRepWithData:[NSData
dataWithBytes:*previewPixMap
length:GetHandleSize( (Handle)previewPixMap )]];
UnlockPixels( previewPixMap );
would have worked, but it doesn't (wasn't really expecting it to).
Before I went ahead and use the init method, I wanted to find it if
there was something simple that I was missing.
Yes. 'imageRepWithData' is expects the data to be an image in a known
format (TIFF, JPEG, PNG, PICT, etc). All you have is a pixel array, so
of course you're going to have to specify the pixel format and all the
other stuff in the 'init...' method.
