Utility methods for common Image manipulation.

To use this module, add Fuse.ImageTools to your package references in your .unoproj.

Fuse represents images as frozen JavaScript Image objects, consisting of a path, a filename, a width and a height. Once created or acquired, Images can be passed around to other APIs to use, fetch or alter their underlying data. All images are temporary "scratch images" until storage has been specified either through publishing to the CameraRoll or other.

On Android using this API will request the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions.

Example

<JavaScript>
    var ImageTools = require("FuseJS/ImageTools");
    var Observable = require("FuseJS/Observable");

    var imagePath = Observable();
    var base64Image =    "iVBORw0KGgoAAAANSUhEUgAAAA8AAAAPAQMAAAABGAcJAAAABlBMVEX9//wAAQATpOzaAAAAH0l" +
                        "EQVQI12MAAoMHIFLAAYSEwIiJgYGZASrI38AAAwBamgM5VF7xgwAAAABJRU5ErkJggg==";
    ImageTools.getImageFromBase64(base64Image)
    .then(function(image) {
        imagePath.value = image.path;
    });

    module.exports = { test: new Date().toString(), image: imagePath };
</JavaScript>
<Image File="{image}" />
