Customising the background image colour of the canny image #56

Closed w9914420 closed 8 years ago

Hello

i was wondering if it is at all possible to customise the background colour of the canny demo from black to a colour of ones choosing.

https://inspirit.github.io/jsfeat/sample_canny_edge.html

ideally I would want to have a transparent background if possible and maybe the option to change the colours of the line edges to another colour apart from white.

I would appreciate any advice/help that you can give.

well this has nothing to do with jsfeat. it gives you the black and white pixels so that you can see where is the gradient goes. how do u render it to screen is up to you. so please refer to JavaScript image operations to solve it.
