Hello,
let's say I have given an image of distance values, which I display with
the jet colormap. Now if there are invalid pixels within the image they
have the value -1 or -2. Is there a way to display just the "valid" image
with the jet colorbar and the -1 pixels as white pixels and the -2 pixels
as black pixels?
Till now I scale the image with vmin, vmax:
>>> vmin = img[(img != -1) & (img != -2)].min()
>>> vmax = img[(img != -1) & (img != -2)].max()
>>> imshow(img, vmin=vmin, vmax=vmax, interpolation = 'nearest')
But how can I now paint the black and white pixels?
Regards,
Markus
