I am developing a small library using javascript, canvas and p5.js that has the ability to load an image from the user's computer. It works by grabbing the image through canvas, removing pixels, and then wrapping the pixels into an array that can then be put into the DOM element. The user can then decide what to do with the image, resize it, save it, load from the local file system, and add it to the DOM. I need to be able to efficiently store the image and retrieve it later on. I'm using the save() function to save the image to a file, which works great, but using this method isn't really efficient as it seems to overwrite the file every time a save() is called. Is there a better way to handle this? A: In addition to @Phosphor's answer, you can also use Blob.slice to extract a portion of the file: var b = new Blob([ this.data ], { type: 'image/png' }); var b64 = b.webkitBlobURL(); //... or your browser extension var t = document.getElementById('myimage'); t.src = b64; For iOS, you can use the URL method. In case you are using the canvas context, you can draw an image into the canvas first, then use.toDataURL() to get a base64 string, that will work in all browsers. A: The one I've found to be the most effective is to: Store the image in a blob (base64, as this is what Blob.slice() returns) Store the blob in localStorage Retrieve the blob via the Webkit method toDataURL This will mean the web application will have to be 'vulnerable' to changes to the web page, but that is unavoidable if you want to store images. This solution does mean there is a delay in loading images, but with an efficient image loader
