NAME

       mkclicfs - Create Clic File

SYNOPSIS

       mkclicfs [-d] [-p pagesize] [-b blocksize] [-c compression] [-l logfile] [-n cores] infile outfile

DESCRIPTION

       The infile is a loop image (so far only tested with ext3) that is assumed to use pages of pagesize. The outfile is the Compressed Loop
       Image Container (Clic), it will contain X parts with blocksize. mkclicfs automatically discards duplicated pages, unless -d is given.

       The default for the pagesize is 4096, the default for ext3

       The blocksize defines how many pages are grouped together before compression. The default is 32, it is a good balance between overhead and
       compression ratio.

       The compression preset defines on how slow it is or how good it compresses. Compare with xz presets. -c 0 is fast and -c 9 is (very) slow -
       but the compression rate varies a lot - of course depending on the data. Preset 6 is the default.

       The logfile is the logfile that is generated from clicfs -l, clicfs will output the access pattern and mkclicfs will reorder the blocks so
       they are in order.

       The number of cores is by default taken from the system. Sometimes it's wise to not all of them though.

NAME

       plscompression - Set device-compression level

SYNOPSIS

       plscompression(compression)

DESCRIPTION

       Set  device-compression level.  Only used for drivers that provide compression.	This function, if used, should be invoked before a call to
       plinit(3plplot).

       Redacted form: plscompression(compression)

       This function is used in example 31.

ARGUMENTS

       compression (PLINT, input)
	      The desired compression level. This is a device-dependent value. Currently only the jpeg and png devices use these values. For  jpeg
	      value  is  the  jpeg  quality which should normally be in the range 0-95. Higher values denote higher quality and hence larger image
	      sizes. For png values are in the range -1 to 99. Values of 0-9 are taken as the  compression level for zlib. A value of  -1  denotes
	      the  default  zlib   compression	level.	Values	in the range 10-99 are divided by 10 and  then used as the zlib compression level.
	      Higher compression levels correspond to greater compression and small file sizes at the expense of more computation.
