[scikit-image] Convert data to image and then image to numpy.ndarray

Is it possible to convert a data set stored as a numpy.ndarray -> plot the data with a colormap , possibly cm.jet. -> and then store the image pixels to a numpy.ndarray. The data array of the image should have the same shape of the data array used to make the array. The image conversion is only used for getting a visual representation of the data, and normalise it using the cm.jet. So I actually just interested in the RGB values of the colormap normalised input data. IS this possible?
