Description
~~~~~~~~~~~
Unpack.svobject is an external Library-Module for the superview.library.
I supports reading of XPK-packed files and will re-parse these through
superview.library by creating an temporary, unpacked file at the location
"VMEM:" and then retries the specific operation on the file.
So this is just a Dummy-SVObject which does for you the work of
unpacking graphics files before displaying them.
Writing (packing) of files is not possible (yet).
Remarks
~~~~~~~
* VMEM:
* Temporary data will be written to a directory assigned to "VMEM:".
* Compatibility:
* This SVObject is just thought to make your life easier, if you've
to handle many packed files, which you don't want to unpack each time
you want to display them.
Nevertheless it is recommended instead to work with unpacked files,
wherever possible.
If you wish to pack files with PP20 or XPK, please use SuperView's
own SVG file format for this instead.
