Problem with using Images.


Hi All

I’m doing my first step in the julia programming.
I love the concept of the language but all my baby steps are so hard that I’m close to give up.
For example, very simple test I picked up form

using TestImages, Images, ImageView
img = testimage(“mandrill”)

was working fine yesterday morning but today I got an error:
Error encountered while loading “/home/arodionov/.julia/packages/TestImages/6bT9D/images/mandrill.tiff”.
Fatal error:

Yes, I did Pkg.update() yesterday.

I’m running Version 1.0.2 (2018-11-08) on Ubuntu 16.

Cairo rebuild demands root access?

Unfortunately things are in an awkward state right now with regards to libz. Your best bet is to ensue that ImageMagick (or any other libz-loading package) loads before Gtk. You could do this:

using TestImages, Images, ImageMagick, ImageView   # put ImageView after ImageMagick
img = testimage(“mandrill”)

or, if you’d rather not need to be explicit about ImageMagick,

using TestImages, Images
img = testimage(“mandrill”)
using ImageView

Sorry for the inconvenience.


Thank you so much Tim for you fast and helpful answer!

It works fine now.
