javascript - Uint8ClampedArray image to jpg/png -


i have image stored in uint8clampedarray in web page. i'd save image in jpg/png file on server.

i can access image executing code: 

canvas.putimagedata(imgdata,0,0);  // create new img object var image=new image(); // set img.src canvas data url image.src=canvas.todataurl();

now in image.src have long string represent image.

i have 2 question:

  • do need use canvas img source or can without using it?
  • is possible convert image in jpg/png file in browser or have process in server?

i'd better understand how process works. help!!
