/* This program takes a PCL graphics file and will try and
* optimize the compression.
*/
/*
* This program was first a filter by Dean to compress pcl graphics.
*
* This program now will do optimal compression using modes 0,1,2 and 3
*
* Also, this program will take compressed input.
*
* Input and output formats are standard pcl.
*
* Imaging files will be compressed too.
*
* pclcomp does not take advantage of Y-Offset for blank areas.
* This is because Y-Offset creates white areas, but we don't do enough
* parsing to determine what value "white" has. An application that
* can assume white values could make use of this sequence.
*
* pclcomp does not do any of the block compression modes (4-8).
*
* There are a few obvious inefficiencies that I will fix later.
*
* Speaking of mode 3, there is a possible problem because each of the
* output row storage areas are 2* size of what mode 0 would be. This
* is clearly sufficient for modes 1 and 2, but it may not be for mode
* 3. But I cannot think of a case in Mode 3 where this would be a problem.
*
* An additional enhancement would be to compare all the planes in a
* multi-plane file (color) and if nothing changed, using mode 3, just
* output a single <esc>*b0W.
*/
/*
* Usage: pclcomp [-v] [-0] [-1] [-2] [-3] [-z] [-n###] < infile > outfile
*
* Pclcomp will do graphics compression based on compression modes 0, 1, 2
* and 3. (Mode 0 is uncompressed). Pclcomp will accept all modes, and
* will attempt to optimize by selecting the best output mode for each
* row (or plane) of data. By default, pclcomp will use all 4 modes, but
* the user may restrict which output modes to use with the -0123 options.
* For example, to use pclcomp for output to a PaintJet which only knows
* modes 0 and 1 (the XL also understands modes 2 and 3), one would use:
*
* pclcomp -01 < infile > outfile
*
* Note: Mode 0 should always be allowed. None of the other modes is
* guaranteed to be better than mode 0 in all cases.
*
* The 'v' option tells the number of rows (planes) of data input and output
* in the different modes (to stderr).
*
* The 'z' option is useful for PaintJet files using only modes 0 and 1, it
* does zero "stripping" as the PaintJet will do zero "filling".
* NOTE: 'z' now means do NOT zerostrip.
*
* The 'n' option is to change the default number of pixels in a picture.
* The proper way to set the pixel width is with the source raster width
* sequence <esc*r#S>, but soo many applications just assume the default,
* which is different on different printers, so I am providing this
* command line option to set a new default. One could also change the
* DEFAULT constant below (make sure it is a multiple of 8). Currently
* it is set to 8" at 180 dpi (1440), but for 300 dpi, set it to 2400.
*
* default is now 2400 (for 300dpi ala LaserJet).
