Winfunktion Mathematik is an old German mathematics program released in 1998. The 138 file extension is associated with version 8.0 of the program.
A 138 file stores data for Julia set mathematical fractals used by the program. It is a specialized data file rather than a general-purpose image format.
Winfunktion Mathematik later reached version 22. It is not known whether the newer versions still use 138 files for Julia set fractals, so compatibility with current releases should not be assumed.
Open a 138 file with Winfunktion Mathematik Plus on Microsoft Windows. Version 8.0 is the version associated with this file type.
Newer versions of Winfunktion Mathematik may not support this older format. If the file does not open, use the original version or an installation that can access the corresponding Julia fractal functions.
The 138 file is a program-specific Julia fractal data file, so conversion should be performed from within Winfunktion Mathematik rather than with a general image converter.
If Winfunktion Mathematik can open the file, use any export or Save As function it provides to create an output in a supported format.
