3They are usually properties display devices.. I'm positive you dont have *default brightness and contrast* for images.. – techfoobar May 15 '13 at 12:03

jQuery wasn't designed to manipulate images (or discover their properties, beyond width and height) – snumpy May 15 '13 at 12:03

2canvas html5 looks better for this – A. Wolff May 15 '13 at 12:04

Do you have any idea of how to adjust brightness/contrast of image using slider ? – user2307273 May 15 '13 at 12:04

No, we can have any idea because slider means nothing (or means lot of things) – A. Wolff May 15 '13 at 12:05

There are ways to *'how to adjust brightness/contrast of image'.* But you'd need to do the research to find them out for yourself. – George May 15 '13 at 12:06

thanks for this url @Shanimal. I was looking something like it since morning and just got Pixastic but it's not working fine for me. I am going to try it which you suggest me If any problem occurs Please help me. – user2307273 May 15 '13 at 12:09

@user2307273 there are many good libraries out there, some solutions are on the server side. I usually prefer the browser based solutions but if you need compatiblity across devices (ios) and older browsers you should go with a server side solution. – Shanimal May 15 '13 at 12:13

This glfx.js does not support webGl and it is problem in most of the browser. Please give me any other solution. – user2307273 May 30 '13 at 08:44

There's options out there. a) pixastic (as you mentioned) b) detect WebGL and instruct users to turn it on c) server side (imagemagick, imagefilter, etc...) d) flash (which I used to develop 2d+3d photo transitions professionally for several years e) css filters. Which direction do you want to go? – Shanimal May 30 '13 at 14:42
