Imports an image file into the document as a Base64-encoded string, and displays this string as an image in JSON Grid View. Image file formats that are supported for import are: PNG, JPEG, BMP, GIF, TIFF.
Exports a Base64-encoded string to an image file. You must ensure that the image file name you give has a file extension to match the image type specified in the Base64 encoding. If the string being exported is not Base64-encoded, then a file with the file name you specify will be created but will not have any content.
