I had an error at compilation time with MacOS Ventura, Apple Silicon, homebrew with Imlib2 dependency installed.

% make
cc -c -Wall -pedantic -std=c99 -D_DEFAULT_SOURCE -I/opt/homebrew/include/X11 `pkg-config --cflags Imlib2` -o icat.o icat.c
In file included from icat.c:39:
/opt/homebrew/Cellar/imlib2/1.10.0/include/Imlib2.h:45:10: fatal error: 'X11/Xlib.h' file not found
#include <X11/Xlib.h>
         ^~~~~~~~~~~~
1 error generated.
make: *** [icat.o] Error 1

I modified the Makefile this way :

-       CFLAGS:=$(CFLAGS) -I/opt/X11/include `pkg-config --cflags Imlib2`
+       CFLAGS:=$(CFLAGS) -I/opt/homebrew/include `pkg-config --cflags Imlib2`

Now the compilation is ok 👍

% make
cc -c -Wall -pedantic -std=c99 -D_DEFAULT_SOURCE -I/opt/homebrew/include `pkg-config --cflags Imlib2` -o icat.o icat.c
cc -o icat icat.o  `pkg-config --libs Imlib2`

Hope it helps...

I just came across icat. I am using Arch Linux. I tried displaying an image with icat, but it always displays in 256 colour, instead of 24 bit.

My terminal already supports 24 bit colour as can be seen from the following test:

I tried searching the internet for enabling 24 bit colour support for icat, but all I could up with is that it is supported by default in icat.
So my question is how do I get the pictures to display in 24 bit colour.

Just a question. I've never used a 256 color SSH client in Windows...I'm trying to use icat to produce 256 color output in an SSH session to my Ubuntu box, running iCat. I tried running ANSICON and plink, but that doesn't look right either. Any suggestions on the environment on a windows box that would look right?

Thanks

On a Apple Silicon Mac, the make command failed.

➜  icat git:(master) pkg-config --libs Imlib2        
-L/opt/homebrew/Cellar/imlib2/1.10.0/lib -lImlib2

So the lmlib2 is installed.

➜  icat git:(master) make

Hi!
Can you please tag releases? I want to include this nifty program in the MacPorts tree, and using tags for releases would greatly ease the maintainership :)

Thank you very much!

Are there any plans for making deb/rpm packages?

Would be cool if you could add an example image and its icat output to the README.

Hi,

The Euclidean metric ( sqrt(a^2+b^2+c^2) ) does not approximate perceived color distance very well. In my version of this project (this seems to be one of these weird wheels everybody keeps reinventing^^) I used the LUV color space, where the Euclidean metric gives somewhat better (though still imperfect) results.

Also, using the ANSI standard palette (colors 0-16) is unwise for image display since users tend to re-define these colors using color themes in their terminal emulators.

Cheers,

By analogy with cat icat should support multiple image file arguments.

 cat file1.txt file2.txt > newfile.txt  

icat img1.jpg img2.jpg > newfile.ans
