image-width and image-height not calculating about compass-mixins HOT 3 CLOSED

This library doesn't have access to the filesystem to check image dimensions, because it's trying to get close to compass using only sass script. Those would have to be implemented in C++ in libsass or using libsass's custom functions, when they land. sass/node-sass#332

from compass-mixins.

@michaek I see that node-sass added custom functions, but I'm still not able to use image-width or image-height functions. Any update on this?

from compass-mixins.

For those who came across this issue, this library called node-sass-asset-functions provides polyfills for all these functions:

image-url($filename: null, $only_path: false)
image-width($filename: null)
image-height($filename: null)
font-url($filename: null, $only-path: false)
font-files($filenames...)

You can integrate it in your node-sass.
