How-to query for Windows

Hello,
python and github novice here, so pardon me if this is out of order here.

on windows with anaconda, how does one run the following example:
icon-font-to-png --css font-awesome.css --ttf fontawesome-webfont.ttf --list

above has a shell prompt, so i presume is for linux

what i have done on windows are as follows:

pip install icon_font_to_png (on anaconda cmdline, success)
icon-font-to-png --css font-awesome.css --ttf fontawesome-webfont.ttf --list (on anaconda cmdline, failed: 'icon-font-to-png' is not recognized ...)
icon-font-to-png --css font-awesome.css --ttf fontawesome-webfont.ttf --list (on windows cmdline at C:\Users\user\Anaconda3\Scripts>, failed: 'icon-font-to-png' is not recognized ...)

Kindly advise please. TIA

icon-font-to-png --download font-awesome

Some URL that has changed over at FA?

--color Hex value support?

👍 Very nice and most useful utility...

I try --color with hex value, but I got error, icon-font-to-png would support custom colorize by hex values.

Successfully installed icon-font-to-png tinycss requests pillow six
Cleaning up...

I've been able to successfully install and run icon-font-to-png on a linux machine however and it appears the issue might be related to the install of pillow. I'm not too familiar with pip and I might be posting this in the wrong repository, if so, please let me know!

NoneType error on bbox

Hi,

Trying to workaround FontAwesome awkwardness, i hit a bug with bounding box management. Here is the output:

I don't understand why there is an if bbox as if bbox can be None, but border_* lines requires bbox to be defined. Can you give me a clue ? I can send you a patch.

KeyError in PIL with Keyrune

When I try to convert all Icons from https://github.com/andrewgioia/Keyrune I get a KeyError because it tries to convert an icon and save it as '.png' without prefix.
The list seems to contain an empty name as first element. I don't know anything about icon fonts, so I can't tell who is wrong here. Maybe allow the tool to ignore these errors and just tell the user that it couldn't convert it?
Thanks for the tool btw :)

Could not open requirements file: [Errno 2] No such file or directory: 'icon-font-to-png/requirements.txt'

List available icons using --list fails

I am using the current version, installed via pip.

Downloading the font using:

icon-font-to-png --download font-awesome

worked without issues - as a result i got the .css and the .ttf file.

But if i try to list all icons using:

icon-font-to-png --css font-awesome.css --ttf fontawesome-webfont.ttf --list

i get no output at all.

How to know downloadable available fonts name?

Is there any command for listing, downloadable available fonts name.
