/* Configuration ************************************************************/
/* This is a simple unit test for the TIFF creation library at apps/graphic/tiff.
* It is configured to work in the Linux user-mode simulation and has not been
* tested in any other environment. Since the example also depends on some
* other logic to mount a file system, currently it will only work as an NSH
* built-on, i.e., if the following is defined:
*
* CONFIG_NSH_BUILTIN_APPS=y
* CONFIG_EXAMPLES_TIFF_BUILTIN=y
*
* Other configuration options:
*
* CONFIG_EXAMPLES_TIFF_OUTFILE - Name of the resulting TIFF file
* CONFIG_EXAMPLES_TIFF_TMPFILE1/2 - Names of two temporaries files that
* will be used in the file creation.
