Expected Behavior

Would like to create a new Jimp object from a buffer

Current Behavior

with this code:

new Jimp({
    data: Buffer.from(
      `<svg><rect x="0" y="0" width="${width}" height="${height}" rx="${width / 2}" ry="${height / 2}" /></svg>`
    ), 
    width: width, 
    height: height
  });

I get the error message:

Error: w and h must be numbers

Steps to Reproduce

run this code :

new Jimp({
    data: Buffer.from(
      `<svg><rect x="0" y="0" width="${width}" height="${height}" rx="${width / 2}" ry="${height / 2}" /></svg>`
    ), 
    width: width, 
    height: height
  });

Context

Basically what I'm trying to do is generate a Jimp object with rounded corners to use as a mask on another image (i.e. with myImage.composite(maskFromBuffer,0,0)
