HP2XX, A HP-GL Converter
3.4 Swapping
hp2xx allocates memory for an internal bitmap dynamically.
Large pictures, high resolution, and use of colors may combine to
let your computer run out of memory (especially on non-swapping operating
systems like DOS).
In this case, hp2xx swaps the bitmap to disk, slowing down
considerably. Redirecting swapping to a fast disk, preferably a RAM disk,
might speed up things. You can replace the default swap file
`hp2xx.swp' using `-s `swapfile''.
NOTE: If for some reason hp2xx is aborted during swapping, you might
have to delete the swap file manually.
