Imread a pn

[Peter Jan]

Hi,

I encountered a problem with [im, cmap, alpha] = imread(image.png). The file attached is the png file that gives me the following results:

im = matrix with logical ones

cmap = [ ]

alpha = matrix with logical zeros

size of im and alpha is equal to the size of the image.

I have tried the same with a random other .png file and that works fine. Also, I am able to read the attached file on an old windows laptop running octave 3.2.

I am running octave 3.8.0 on Ubuntu 13.10.

Can anyone help me out with how to fix this? What could be causing this or how could I work around this?

thanks,

PJ
