/**
|
|
* @module FileToArrayBuffer
|
|
* `FileToArrayBuffer` is a component that will allow you to pick a file from the local file system. Once
|
|
* loaded, this file will be emitted as a JS ArrayBuffer to the passed `onChange` callback.
|
|
*
|
|
* @example
|
|
* ```js
|
|
* <FileToArrayBuffer @onChange={{action (mut file)}} />
|
|
* ```
|
|
* @param onChange=null {Function} - The function to call when the file read is complete. This function
|
|
* receives the file as a JS ArrayBuffer
|
|
* @param [label=null {String}] - Text to use as the label for the file input
|
|
* @param [fileHelpText=null {String} - Text to use as help under the file input
|
|
*
