The uploadBinaryHelper helps with uploading binary files. The Picture Upload sample app shows how to use this function.
The function has the following parameters:
|An Appery.io REST service instance with POST method to create a file in Files collection.
|A base64 string of the image.
|A name with which file will be stored. If empty, current date will be used as name.
|Image format as .jpg or .png. If empty .jpg is used.
In the following example web_upload is the name of a service instance on a page, and image_base64 is a local storage variable that stores the image in base64 format.
