Clipping JPEG Images Into Non-Rectangular Polygons Using polyClip.js
October 29th, 2011 by zoltan · 8 Comments
Up until now, if a developer needed to clip an image in a non-rectangular shape, it was necessary to save the image as a PNG with an alpha channel. If the image is a photograph, the file-size balloons up to unacceptable levels. My new library, polyClip.js, allows developers to clip these images using photograph friendly JPEGs instead.

May 12th, 2011 by zoltan · No Comments
Even though onforminput is deprecated, oninput will allow developers to do dynamic calculations on forms with little JavaScript knowledge. Unfortunately, it doesn’t work in IE8 and lower, and there are some small bugs in IE9′s implementation when trying to delete characters inside a form field. So I implemented a fix for these issues with an update to my cross-browser HTML5 Forms polyfill, html5Widgets.

Should something this useful and easy-to-use be abandoned?
