All the decent browsers (Chrome, FX, etc) now support built-in spell checking. However the popular but rubbish axis of IE doesn't (not even IE8 - pointless 'accelerators': yes, much needed dictionary support: no). Unless you download an excellent free plugin, but you can't expect corp users to do that. Our clients want spell checking i...
When researching JavaScript conditional comments for IE, I stumbled upon @cc_on. This seems to work. However, the wikipedia entry on conditional comments provides the following code for more robust IE detections, specifically IE6: /*@cc_on @if (@_jscript_version > 5.7) document.write("You are using IE8+"); @elif (@_jscri...
Assume a group of data points, such as one plotted here (this graph isn't specific to my problem, but just used as a suitable example): Inspecting the scatter graph visually, it's fairly obvious the data points form two 'groups', with some random points that do not obviously belong to either. I'm looking for an algorithm, that would ...
How would I go about doing a detect to see if the browser is either firefox, ie (but not ie6), opera, chrome or safari by using feature detection? ...
I have a whole bunch of images of illustrations that I would like to crop to a smaller preview size. The problem is that I want to crop them to show an "interesting" part of the illustration (ie avoid areas of whitespace). The images typically have a flat color or a subtle gradient for the background. They are mostly vector style artwo...
Is there any way to detect which windows XP theme is in use? I suspect that there is no specific api call you can make, but you may be able to figure it out by checking something on some DOM element, ie feature detection. Another question: does the classic theme even exist on windows vista or windows 7? edit - this is my solution: fu...
I need to detect IE6 in order to work around the lack of position:fixed. I've been using a simple regex: var isIE6 = /msie|MSIE 6/.test(navigator.userAgent); This works almost all the time, except for the user whose browser claims to be both IE6 and IE7: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Mozilla/4.0 (compatible; MSIE...
I've written a script to test for SVG support in the IMG tag: function SVGinIMG() { var SVGdata = 'data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIyNzUiIGhlaWdodD0iMjc1Ij48L3N2Zz4%3D' var i = document.createElement('img'); i.setAttribute('src',SVGdata); return i.complete; } window.onload ...
I am implementing a Harris corner detector for educational purposes but I'm stuck at the harris response part. Basically, what I am doing, is: Compute image intensity gradients in x- and y-direction Blur output of (1) Compute Harris response over output of (2) Suppress non-maximas in output of (3) in a 3x3-neighborhood and threshold ou...
