Extend to a specified width and height in single operation without knowing the prior width or height

[twilson90]

It appears extend() only allows inputs of left, right, top and bottom, but it would be really convenient if there was a way to extend an image to a specified width or height without having to calculate the images width or height and using the differences in extend(), or using toBuffer on the image and creating a new image using composite(), both of which require async operations.

Is this already a feature? If not it would be nice.

If you only want to extend along one axis ("letterbox") then .resize({ width, height, fit: 'inside' }) kind of does this.

Otherwise, yes, you'll need to calculate this using the metadata. Although it is async, the metadata() call is usually very fast as it does not decode any pixel data.
