Anti-aliased Rounded corners with JQuery

Rounded CornersRecently I’ve been searching for a method of creating nice looking rounded corners with Javascript & JQuery.

First I found the “JQuery Corner” plugin for rounded corners, but was disappointed that it did not include smooth, anti-aliased corners.

I then did some more google-trawling and found this post, which contained a modified version of Curvy Corners for use with JQuery. Now this script was much much better.

However…the filesize was a massive 40kb, way too big for production use, and to make things worse the code was not compatible with packer so I could not reduce the filesize.

Well, I got busy, and fixed the errors. It is now fully packer friendly meaning easy rounded corners in JQuery at only 9kb 8kb 15kb 20kb 16kb 10kb. Excellent. Read more for the download link.

Demo and download

See the demo page here

You can also grab the plugin from Google Code.

Download JQuery Curvy Corners Version 1.9

The packed version is only 10kb, the uncompressed version is 23kb (thats half the size of the original script!).

Quick example

To make a curvy cornered box simply use:

1

		$('.round_this').corner();

Thats all there is too it. A great script!

    Also, is there a drop shadow / outer glow plugin which would work with the rounded corners? :)

    • Switched: From Shared to VPS

      It’s been about two weeks now since I made the transition from a shared reseller hosting account to a VPS (Virtual Private Server) account – impressions so far, excellent performance but fiddly to configure.

      The reason I wanted to change from shared hosting was the fact the server was always being hacked (even though ALL my scripts were secure), there was frequent downtime, support blamed me for problems every time, and it was slow as hell.

      Those used to a shared hosting environment would probably not know where to start when faced with configuring a VPS. Luckily, a lot of it was pre-configured when I received my account – certainly some of the major security holes were patched. I was not satisfied with those however. As a victim of hacking in the past (previous host swears it was not there fault, something I don’t believe) I took extra care to secure it as a much I could – configuring brute force detection, the firewall, installing mod security (excellent rules for that here: http://www.atomicorp.com/wiki/index.php/Atomic_ModSecurity_Rules) and going though multiple guides (like this one: http://www.webhostingtalk.com/showthread.php?t=468168) with a fine-tooth comb.

      The result? My pages are loading at least 6 times faster, I have had no down time (or at least have not noticed any), and I feel in control and happy. No longer am I at the mercy of shared hosts :)

      If your interested, I chose ServInt as my provider as they offered a great deal, as well as being a managed service (so I’m not on my own if I screw things up). I was tempted by the bells and whistles of Media Temple, but felt the ServInt service was better value.

    • Download Monitor 3.2.2 Maintenance Release

      Download Monitor has received some more love and has been updated. Here’s the change log from the new version:

      • Small bugfix in uploader.php – cat ID
      • Changed stats graph calculation – thanks lggemini
      • Changes to headers in download.php to avoid caching
      • File Browser fixes – $root was clashing with something….
      • exclude_cat works in all sections of download_page now
      • Removed hardcoding of /uploads/
      • Added action to download.php – should be able to use it to stop a download if you want – maybe limiting downloads per day or something? Whatever you want…
      • Made it so if you post new file on ‘edit’ screen, the post date is updated.
      • Fixed the ‘blank meta’ section which blanks out custom field values when nothing is set.
      • Moved ‘allow_url_fopen’ check.
      • Someone said downloads don’t work with spaces in the name. They do! Wasting my time sonny…
      • All work and no play make jolley a dull boy
      • Had to rename capabilities so they work. Apologies if you have to set this up again! Cheers to Mark Dingemanse.
      • {category_ID} custom format tag added. Useful if you want to send someone to its category on the DL page I guess. Also added {category_other} so when no category is set “other” is shown – this is because the download page can show an ‘other’ section if you want it to.
      • You can now manually edit the post date on the edit download screen.

      If you have edited capabilities for download monitor user permissions, you’ll have to again sorry! This is because I named them too long. Also, you should check your forced downloads still work because there was a logic error meaning they may not have been forced after-all…

      Enjoy.

    • Mahousive update to Download Monitor (3.2)

      Today I completed the update for the Wordpress Download Monitor Plugin – many tweaks, fixes, and features added. There were no changes to the database structure so people upgrading should be fine. Here is the list from the change log:

      • {user} tag added for custom formats
      • ‘autop’ option fix
      • Download page buttons applied with CSS so they are easier to customise/translate.
      • Fix for pagination bug after editing a download
      • Category output fix on edit downloads screen
      • Category urls on download page use ID rather than name to prevent errors when cats have the same names.
      • exclude_cat added to download_page shortcode
      • Localised ‘hits’ ‘date’ ‘title’ on download page
      • Option to disable the download logging
      • Read file ‘chunked’ some people found large files were corrupted so this should help (fingers crossed)
      • Added show_tags option to download page – displays x amount of tags on the download page.
      • File Browser root setting and download.php logic/mime types modified thanks to Jim Isaacs (jidd.jimisaacs.com)
      • Interface Improvements
      • Bulk edit categories, custom fields, tags, member only downloads
      • Added roles for download monitor admin – should be able to use with a role manager plugin if you want anyone other than admin to access the admin section e.g. http://wordpress.org/extend/plugins/capsman/
      • Change redirect after add
      • Edit Cat names/parents
      • Dedicated tags and thumbnails fields (they still use meta table though)

      And yes, those category link bugs are fixed at long last, and you can edit category names finally. Phew!
