Numpy image - rotate matrix 270 degrees

image-manipulation, matrix, numpy, python

Solution

You can tell `rot90` to rotate several times, this should work:

rotated = numpy.rot90(orignumpyarray,3)

Problem

I've got a Numpy 2d array that represents a grey-scale image and I need to rotate it 270 degrees. Might be being a bit thick here but the two ways I can find to do this seem quite... circulous: ``` rotated = numpy.rot90(numpy.rot90(numpy.rot90(orignumpyarray))) rotated = numpy.fliplr(numpy.flipud(numpy.rot90(orignumpyarray))) ``` I'm thinking there must be a better way to do this in one operation. Basically a rot270() function? Any ideas?
