Is there a way to make a button or pad look like.....

A image of a button ,like can I import a JPEG or a pic file to put under a transparent button or pad?

No that's not possible, but it is possible to recreate the picture with canvas and use that

Can u give me an example? I've never used canvas.......thanks

You can use this site to convert SVG to Canvas code. You just have to modify it a bit to fit the Lemur Canvas Syntax. All info on that can be found in the addendum.

ok i found some cool buttons and faders ...now please can u guide me on how to get the images to a canvas....i tried the convert tool ,but dont know where to paste the html5 code

I have tried everything and found some great looking faders and buttons but could not get them into lemur I would use the convert program and the colors would be gone and other times it would crash lemur ....oh boy if I could use these faders!!!

I think you should just try and recreate it manually with canvas. Using that converter will most likely cause many bugs and be exhaustive. It may be frustrating, but manually to me is the best way to go.
If the images are really simple (in shape, angles, colors, etc) then the image converter might work fine. But then again, if its really simple you could just draw it in canvas yourself!
