Note: I have put this program on expo.lcs.mit.edu in the "contrib" directory. -- Craig McGowan - G.E. CRD Release Notes for xwd2ps The program xwd2ps allows standard X11 color window dumps to be printed on color or monochrome PostScript printers. It was originally written to enable the printing of 24 bit images on a color PostScript printer. Because of the large size of the typical 24 bit color image, much time was spent increasing the printing performance (run length encoding is used to reduce the size of the downloaded PostScript file which dramatically decreases transmission time). A typical full color image prints much faster with xwd2ps than the other programs currently available. Another performance improvement in xwd2ps is the use of a color map in the PostScript file. This allows just the 8 bits of display information plus the colormap to be downloaded, rather than converting a color mapped display into full color PostScript (about a 3*x savings in file size and transmission time). In addition to performance enchancements, xwd2ps supports a number of output ornamentations (labels, company logo, thin borders, etc.) which are useful when giving presentations. These features are being used at G.E. Corporate Research and Development. Currently, the program supports and has been tested with xwd window dumps from 4 bit, 8 bit, and 24 bit displays. It has been ported to 680x0, sparc, 80x86, mips and VAX architechures. While it has not been possible to test all possible configurations, it is believed that the code is quite portable. We do not guarantee support for this package, but we are interested in improving it and fixing bugs. We will attempt to release new versions periodically. In order to facilitate this, we have set up the mail alias "xwd2ps-support@crd.ge.com". Please send your comments to this address. Please note the copyright notices below. Craig A. McGowan Robert C.
