The static library implementing this backend. This environment variable specifies the list of directories that may contain the configuration file. If the value of the environment variable ends with the directory separator character, then the default directories are searched after the explicitly spec ified directories. If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed.
Smaller levels reduce verbosity.
Symptoms of these errors are skewed images. The PINT 0.5e interface does not provide a way to deter mine valid ranges for DPI, modes, and scan sizes. So, the SANE backend queries the PINT device, and dynamically dis covers valid ranges by doing a binary search. This means that the driver takes longer to initialize than seems nec essary. X and Y resolutions are assumed to be the same.
