Calculation of width OR height based on original image

[maku]

For the resize method it would be great if you are able to provide only one value (newWidth OR newHeight) and the other value is calculated based on the ratio of the orignal image.

@maku You might be interested in this older fork: https://github.com/bartholomej/ng2-pica/commits/aspect-ratio

Usage
When keepAspectRatio is true then width + height parameters
become maxWidth + maxHeight parameters

Just add true as 4th parameter. It is optional and default value is false => without breaking changes.

let newWidth = 2048;
let newHeight = 2048;
let keepAspectRatio = true;

this.ng2PicaService.resize([someFile], newWidth, newHeight, keepAspectRatio).subscribe((result)=>{
  //all good, result is a file
  console.info(result);
}, error =>{
  //something went wrong 
  console.error(error);
});

If you wanna try it right now, you can install it like this (temporary solution):
Just add to your package.json
"ng2-pica": "git+https://github.com/bartholomej/ng2-pica.git#keep-aspect-ratio"

But I'll make a PR ;)
I made PR: #7
