toimage(arr, high=255, low=0, cmin=None, cmax=None, pal=None, mode=None, channel_axis=None)¶
Takes a numpy array and returns a PIL image.
This function is only available if Python Imaging Library (PIL) is installed.
The mode of the PIL image depends on the array shape and the pal and mode keywords.
For 2-D arrays, if pal is a valid (N,3) byte-array giving the RGB values (from 0 to 255) then
mode='L', unless mode is given as ‘F’ or ‘I’ in which case a float and/or integer array is made.
For 3-D arrays, the channel_axis argument tells which dimension of the array holds the channel data.
For 3-D arrays if one of the dimensions is 3, the mode is ‘RGB’ by default or ‘YCbCr’ if selected.
The numpy array must be either 2 dimensional or 3 dimensional.
