Handle .ico

[pixelastic]

Could be nice to be able to do a catimg ./favicon.ico to see what it looks like :)

Hi!
That would be indeed nice. The lib I use for loading images doesn't handle ico files. Do you know about any tiny lib that does that? Otherwise I'd have to code it myself as I'm concerned about the final executable file size

I know that the convert command utility that comes with ImageMagick should handle ico files.

$ convert favicon.ico txt:-

Sorry for the late answer. Adding support for those enumeration and adding a note on the help and readme seems enough. I'll find the time to do it someday 😅

I just tried using catimg with an ico file, and it worked fine.

[posva]

You must have used the script 😄

I'm not sure I'm following here. I just tried with http://www.google.com/favicon.ico and it failed

[posva]

There's the C program that is installed with brew and compiled with the Makefile and there's also a shell version at project's root that relies on ImageMagick to print images and therefore handle pretty much any format ImageMagick can handle

[pixelastic]

I tried both version, script and binary and both were giving me errors with Google favicon:

Binary:

Script:

I then started hacking on my own Ruby version (repo here) and it's now working. It is way slower than your binary, though.
