Base64-encoded files (MIME)


If PMView detects a file that has been Base64-encoded it will automatically decode the file. The decoding will be done transparently, thus it does not require a separate reading or processing step. This means that encoded files can also be displayed progressively if the graphic format in the file allows it (e.g. GIF, JFIF, PNG, etc.).


The Base64 encoding scheme is used by MIME aware software. A MIME message can contain multiple files. However, PMView only reads the first Base64 encoded image in the file. If the file contains several images you need to use a text editor and split the file into several files if you want PMView to read the files. In this case it is probably more convenient to use a MIME reader that is able to automatically extract all the parts of the message for you.
