.save() function should return a success or error callback if canvas is not drawn or create an isBlank function

[danicomas]

Current behavior
.save() function is only fired if canvas was drawn

Expected behavior
.save() function should return a success or error callback if canvas is not drawn

That's an interesting idea but .save() can't return a success or error callback because then it would not be chainable with other jqScribble methods.

Let's continue the discussion but I'm going to close this since it's more a feature request than an issue.

I have created an isBlank function I hope it is well for you @jimdoescode
