Resize an image
We can use the targetSize
property on the createDefaultImageWriter
function to automatically resize images to fit a target width and height.
This example is a bout automatic resizing of the output image, to let the user resize the image in the editor we need to enable the resize plugin.

By setting the fit
and upscale
properties we can further control how the editor scales images. By setting upscale
to true images smaller than 256
× 256
will be upscaled to fit the bounds.
If the image isn't a square it won't fill the square bounding box, the image will be scaled up until one of the edges is 256
pixels in length. To always cover the square target size we can set fit
to 'cover'
.
