I am trying to use stack over flows markdown editor showdown by its Angularjs Module ng-showdown

Everything is going fine but the image that are getting included are in their actual/original size.

how to resize them to fit in the text?

Given below is a dummy that is showing the same problem.

Many thanks!!!

      var htmlValue = $showdown.makeHtml($scope.mymarkdown)

    })

Solution

  • Disclaimer:

    I'm the current showdown's project leader.

    As per showdown's documentation:

    parseImgDimensions: (boolean) [default false] Enable support for setting image dimensions from within markdown syntax. Examples:

    ![foo](foo.jpg =100x80)     simple, assumes units are in px
![bar](bar.jpg =100x*)      sets the height to "auto"
![baz](baz.jpg =80%x5em)  Image with width of 80% and height of 5em

    So you need to enable the option parseImgDimensions and then use the above syntax.

    Example

    Passing options in the constructor:

    var converter = new showdown.Converter({parseImgDimensions: true});

    or

    var converter = new showdown.Converter();
converter.setOption('parseImgDimensions', true);
