vdltodmx(1)						      General Commands Manual						       vdltodmx(1)

NAME
vdltodmx - dmx configuration file parser and printer SYNOPSIS
vdltodmx infile outfile DESCRIPTION
vdltodmx reads the input file, which should be in VDL configuration file format. After a successful parse, a file in Xdmx configuration file format is written to the output file. The VDL file format is used with xmovie, which is available from http://www.llnl.gov/icc/lc/img/xmovie/xmovie.html EXAMPLE
Given the following VDL-format file: 0 2 # # 2560 2048 Left two-thirds [restrict=*:2] 2 :2.1 1280 2048 0 0 0 0 :2.2 1280 2048 1280 0 0 0 4 1280 1024 0 0 1280 1024 0 1024 1280 1024 1280 0 1280 1024 1280 1024 # 2560 2048 Right two-thirds [restrict=*:2] 2 :2.2 1280 2048 0 0 0 0 :2.3 1280 2048 1280 0 0 0 4 1280 1024 1280 0 1280 1024 1280 1024 1280 1024 2560 0 1280 1024 2560 1024 the following DMX-format file will be produced: # # virtual "Left two-thirds" 2560x2048 { display :2.1 1280x2048; display :2.2 1280x2048 @1280x0; } # virtual "Right two-thirds" 2560x2048 { display :2.2 1280x2048; display :2.3 1280x2048 @1280x0; } BUGS
If the VDL file is not in the expected format, the program will probably dump core. SEE ALSO
