将Canvas绘图保存在html5 phonegap中

Question

I have draw drawing on canvas and want to save it as image(jpg/png) on phone internal memory. How can I do this. Any suggestion.

Answer 1

You basically have two choices to do this.
1) Use Phonegap filewriter api here

2) you can write a custom phonegap plugin, basically send the image data to ios/android and have objective C / java write the image to the filesystem.

Each of these has benefits. I prefer the phonegap plugin, but I have more experience with plugins. The phonegap api would be quicker though, if your needs are basic. Good Luck!
