width (-w) handling depending on resolution #47

Hi,

I'm playing around with catimg (the c app, not the script) and don't fully understand the width (-w) parameter.

Especially I don't see why setting the resolution to 1 or 2 has an impact on the image width. The terminal width (tput cols) is the same in both scenarios, no? Is it supposed to behave like that?

the resolution makes one pixel span over two characters or not. then the width uses that count, so -r 1 will produce a larger image. In other words, the width isn't in terms of columns but rather in term of rendered pixels

Ok, I see. Thanks for clarifying it ... it's quite confusing but nevermind
