distortion

[michaelaye]

hi!
i'm trying out this amazing idea.

Using this URL:

I'm getting quite a bit of distortion:

Do I maybe have to adapt something in my Terminal settings? I'm using iterm2 (v 3.0.14 on macOS 10.11.6), which is quite complex with a lot of settings and I'm not very firm on terminal technology, so I might well miss something, but I can say that the terminal emulation is set to:

• Character Encoding: Unicode (UTF-8)
• Report Terminal Type: xterm-256color

Maybe my funky zsh prompt is messing things up?

Thanks for any help!

This is what it looks like for me:

The quality is so-so because the image is so wide and there is text(?) in each corner of the image? You can try to zoom into a specific section using the -srcwin x y xwidth ywidth option.

You can also reduce the number of unicode characters used with -unicodes 2 (or any other number).

This is zooming in:

Those little thin lines are due to the font, for example, try Monaco to see the difference. Also try -unicodes 1 and -unicodes 2 to see how it changes the rendering.

My font is 12 pt Monaco?

Changing font doesn't really "fix" the problem. It's due to the fact that you are approximating an image by text characters so it's never going to be perfect. If you want perfect and since you are using iTerm2, use my other tool: https://www.github.com/daleroberts/bv

Wow, that one works big-ly! ;)
