saveToDisk
Save some content to disk, presenting the user with a dialog to choose the file location.
This method extends the global document
variable, so you can use it like this:
document.saveToDisk("picture.png", bytes, "image/png")
Content copied to clipboard
Parameters
filename
The suggested name of the file to save (users will be given a chance to override it).
content
The content to save.
mimeType
Optional mime type information you can save about the file. For example, if you're saving a PNG image, you could pass in "image/png" here. This information may not be necessary if you're just saving / loading binary or text contents, but it can be useful if you expect something else might consume this file. It will be made available in LoadContext when the file is loaded and will be embedded into the URL returned by loadDataUrlFromDisk.
