What do I need to append to an image URL to flip the image horizontally or vertically. In the documentation it says you can add s## with -c to crop the image, but it doesn't talk about r90 r180 or r270 which works to rotate the image. My question is how do I flip the image using url parameters?

EDIT: Please star this issue if you would like to see this implemented. code.google.com/p/googleappengine/issues/detail?id=6886

    I am under the impression that since the doc stated "available arguments", it means that it is not possible to flip the image using URL parameters. – Ibrahim Arief Jan 12 '12 at 08:56
  • But the rotate arguments are not documented but still work. – Lumpy Jan 17 '12 at 22:44

There is no option that can be appended to the URl to flip an image.

You can add -fv or -fh to the end of your URL, eg. =s280-fh to flip the image.
