    Anti aliasing issue


    I had a recent issue where I was creating transparent png over a background image with gradient.  So as per documentation I had antialias set to true and passed in background colour to try and create the transparent png.  The image rendered but text came out jagged.  I removed the antialias=true so it that it defaulted to false and it all worked nicely.  Think it may be a bug, also hope this post helps anyone else with same issue.

    Ps this is an awesome addition to umbraco and the documentation is a good example of to write documentation, i should pay heed to it whenever I get round to releasing a package!

    Thanks for the bug report, Ismail!

    Yes, it's a bug that setting the ?antialias=true parameter actually causes ImageGen to not antialias rendered text.

    The workaround is to not specify the ?antialias=true setting, since ImageGen defaults to antialiasing text anyway this setting is, strictly speaking, unnecessary. By not setting the ?antialias= parameter you get the antialiasing you wanted in the first place.
