I noticed that if a file is around 70-90kb, this would be the maximum size of a file that can be inserted in the database. Join the strings into one and convert this into byte array. Send the string in an array (contains string in pieces) to WebAPI 3. Now that we can resize the image from any of its corners you might have noticed we can inadvertently change its position on the page. Convert the image to a Base64 encoded string. We are now checking to see which resize-handle has been dragged and we’re moving the image while resizing it so that it appears as though the correct corner remains fixed. First, define the styles for the resize-container and the image.resize-container ) I have scenario to maintain the aspect ratio for the image object. That’s it! That’s all the HTML we need for this demo. In my project im using HTML5 Canvas and FabricJS. In our demo we’re going to start with an existing image: With that in mind, let’s get started!

There are some techniques to improve the quality of images downscaled with canvas, but they are not covered in this tutorial. If quality is important you may find the resized image looks undesirable due to how the browser resampled it. Similar to regular cropResize, cropZoom also takes a width and a height but will resize and crop the image to ensure the resulting image is the exact size you. It makes sense to set reasonable limits on the file size just as you would when uploading a file. Resizing very large images can cause the browser to slow down or in some cases, even crash. Most browsers have good support for these methods, so you can probably use this technique right now, however just be aware of some limitations unrelated to browser support such as quality and performance. We do this by creating an HTML5 element and drawing the image to the canvas at a particular size, then extracting the new image data from the canvas as a data URI. Instead we can resize the image on the client side before uploading it, which is fast. Whilst we could do this on the server, it would require the transfer of a potentially large file, which is slow. In a real world example a website or app might use a technique like this to resize and frame a profile picture before uploading.
