  1. Thanks very much for your help! I have tried what you suggested but the only one I successfully altered was the fillStyle:http://jsfiddle.net/dQppK/257/ Then, after making any of the other alterations in JSFiddle the result section just goes blank and doesn't react:http://jsfiddle.net/dQppK/255/ Another code I found looks like it might be a more efficient way to do the same job, if I alter the pen style to suit my needs, but I can't get the code to work in JSFiddle:http://jsfiddle.net/dQppK/252/ Can anyone suggest where I'm going wrong and whether the third code would be a better source code to use. Thanks
  2. Hello, I recently posted asking how to add the ability to draw in a browser on my website and was advised to look into javascript and specifically canvas. I have never used javascript and am struggling to work out how to adapt some code I've found. Can anyone help please? This is essentially what I want to achieve but instead with a white background and fine dark grey line, and with a smoother line. I also want it to start drawing as soon as the mouse enters area and does not require mouse click. I tried altering the mousedown to achieve this but no success:http://jsfiddle.net/loktar/dQppK/4/ This open source code, although far more complicated than I need, employs the desired line smoothing:http://svg-edit.googlecode.com/svn/branches/2.6/editor/svg-editor.html I think this should link to the code for the above:view-source:http://svg-edit.googlecode.com/svn/branches/2.6/editor/svg-editor.html If anyone can give any help to nudge me along that would be greatly appreciated. Thanks
  3. I've had a quick search and it seems a canvas is the way to go to achieve the desired result. Thanks!
  4. Hello, I am wanting to create a function on my website that allows visitors to use their cursor to draw. The visitor is not required to make any selections to do this. I would have an area where as soon as the cursor moves a thin line or trail will be left wherever the cursor goes - effectively allowing them to draw. This trail would remain until they leave or refresh the site. I have seen this done on a website a few years ago but unfortunately I don't have examples to illustrate. Can anyone offer advice as to how this may be done? Would this require JavaScript or something else? Any advice would be greatly appreciated. Thanks Paul
