ppmtoicr(1)					   ppmtoicr(1)

NAME
       ppmtoicr - convert a portable pixmap into NCSA ICR format

SYNOPSIS
       ppmtoicr [-windowname  name]  [-expand	expand] [-display
       display] [-rle] [ppmfile]

DESCRIPTION
       Reads a portable pixmap file as input.  Produces an  NCSA
       Telnet  Interactive  Color  Raster graphic file as output.
       If ppmfile is not supplied, ppmtoicr will read from  stan-
       dard input.

       Interactive  Color Raster (ICR) is a protocol for display-
       ing raster graphics on workstation screens.  The protocol
       is  implemented	in  NCSA Telnet for the Macintosh version
       2.3.  The ICR protocol shares characteristics of the  Tek-
       tronix graphics terminal emulation protocol.  For example,
       escape sequences are used to control the display.

       ppmtoicr will output the appropriate sequences to create a
       window  of  the	dimensions  of the input pixmap, create a
       colormap of up to 256 colors on the display, then load the
       picture data into the window.

       Note  that there is no icrtoppm tool - this transformation
       is one way.

OPTIONS
       -windownamename
		     Output will be displayed in name (Default is
		     to use  ppmfile  or  "untitled" if standard
		     input is read.)

       -expandexpand Output will be expanded on display by factor
		     expand (For example, a value of 2 will cause
		     four pixels to be displayed for every  input
		     pixel.)

       -displaydisplay
		     Output  will be displayed on screen numbered
		     display

       -rle	  Use run-length encoded format	 for	display.
		     (This will nearly always result in a quicker
		     display, but may skew the colormap.)

EXAMPLES
       To display a ppm file using the protocol:
	   ppmtoicr ppmfile
       This will create a window named	ppmfile on  the	 display
       with  the correct dimensions for ppmfile, create and down-
       load a colormap of up to 256 colors, and download the pic-
       ture  into  the window. The same effect may be achieved by

       the following sequence:
	   ppmtoicr ppmfile > filename
	   cat filename
       To display a GIF file  using  the  protocol  in	a  window
       titled after the input file, zoom the displayed image by a
       factor of 2, and run-length encode the data:
	   giftoppm giffile | ppmtoicr -w giffile -r -e 2

BUGS
       The protocol uses frequent fflush calls to speed up  dis-
       play.  If  the output is saved to a file for later display
       via cat, drawing will be much  slower.	In  either  case,
       increasing  the	Blocksize limit on the display will speed
       up transmission substantially.
