I meet problem when using command line tool "etcpack". I have succeed to use it on Windows. But when I use same options to convert the file on Mac, it failed.
The error message was "conver: command not found"
I have already make the working dir to Mali..../bin, And use ./etcpack as the command.
The command line is:
./etcpack /XXX/a.png /XXX -c etc1 -ext PNG -as
The result is:
sh: convert: command not found
Error: Could not convert input image /XXX/a.png to .ppm
the files in bin fold are:
astcenc composite convert etcpack
Thank you. It works!
I forget to add the bin folder to the PATH. After I add it, I can call convert directly.
And sorry topeterharris, it`s my mistake.
