Thanks to the extract of your file , I guess your raw file is formated as width x height then the whole set of RGBA pixels (32 bits) (width x height times) Here I see you get a 720x1280 image captured..

May the ImageMagick toolset help you to view/convert it in a more appropriate file format. Here below a sample that may help you (ImageMagick convert command, for osx see http://cactuslab.com/imagemagick/ )

# skip header info  
dd if=screenshot.raw of=screenshot.rgba skip=12 bs=1
# convert rgba to png
convert -size 720x1280 -depth 8 screenshot.rgba screenshot.png

If it doesn't work you may try changing skip=12 by skip=8 and/or 720x1280 by 1280x720 ..

Hope that help
