I have two questions about bitmaps: 1) Can Motif handle Fax Group Format in bitmap form? 2) Does it also handle postscript? If so, what routines do I need to call. This is for my supervisor, all help is appreciated. dy03+@andrew.cmu.edu

Can someone tell me an easy way to change the size of an X bitmap? I have a bitmap created using the standard bitmap program which is 80x80, but the picture is in the upper left corner, so I want to shrink the bitmap, to say 23x42. The standard bitmap program ignores the WIDTHxHEIGHT parameter if a bitmap is supplied. Is there some other utility that will do this? I am sure if I edit the text file representation that I will do it wrong. Thanks! Brad Myers bam@cs.cmu.edu

All those different bitmap formats!!! xwd creates one format, bitmap another, then there are TIFF files, Macpaint files and who knows what else... Are there any utilities to convert one format to another, especially xwd and Macpaint to TIFF?

Please don't send any pointers to ftp > sites, I can't access them. Although it is not generally available yet, I have been test a program called deBabelizer for quite sometime now. It not only will convert back and forth between many recognized Mac formats, but also will convert freely between MANY graphic formats used on other systems (IBM PCs, Suns, Amigas, Atari STs, Apple IIs, C-64s, EPSF, TIFF, GIFF, and MANY MORE...). The best part about the way the conversions are done is that each format is handled by an external pair of input/output moudles, making the program easliy extensible to to other formats and allowing update to format readers/writers without having to upgrade the entire program - i.e. at lower cost. In addition to this, the program does tons of processing such as intelligent color reduction to any number of colors, remapping to specific palletes, creating "super palletes" from multiple separate grphics files, removing background colors (useful when working with digitized images), scaling, rotating, trimming, color printing, conversion of separate R, G, & B black and white images into a single color image, batch processing, a very advanced scripting option which, in conjunction with batch processing allows you to convert and process a large group of files effortlesly, and a TON of other features. It is currently being seeded in beta form to game developers (obvious reasons) and site licences are available. The program should be avaiable to the consumer market later this year and I believe the price will be under $200. If you do any significant work with graphics/scanning/conversion, this program is a MUST HAVE. It will be published by a company in Marin called Equilibrium. - Ed Rotberg -

> ftp access is available to anyone with e-mail. > Try sending a help request to > ...bitftp@pucc.bitnet > or > ...uunet!pucc.PRINCETON.EDU!BITFTP There are UUCP sites that block mail to (or, presumably, from) anonymous-ftp-by-mail addresses as a matter of policy; I know of at least one in our immediate (electronic) neighborhood. The problem is that it's very easy for a naive user to ask for 60Mb of stuff without realizing that it has to flow through a 2400bps link (say), which tends to, ah, impair performance for everyone else. To say nothing of running up phone bills, if any call along the path is a pay call. It is true that the site I mentioned that I know is blocking such things does have a mechanism in place for allowing users who are trusted to not abuse the service to get through. I don't know whether other such sites do; I would hope so. So while there is such a service available, it may not be possible to get through, or it may be possible but not easy.... der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu

Please don't send any pointers to ftp >sites, I can't access them. A couple of weeks ago, I asked a similar question. From the replies I got, I think the "xbitmap" utility seems to convert from X bitmaps (not xwd!) to PICT. A far better solution is the Extended Portable Bitmap Toolkit package which converts to and from various bitmap formats. Below I included some pieces of the documentation. I'd like to thank the following people for their replies: Eric Nieuwland nieuwlan@serc.nl Tasuki Hirata sukes@eng.umd.edu davide@dcs.qmw.ac.UK Wayne folta@cs.umd.edu --------------------------------------------------------------- Extended Portable Bitmap Toolkit Distribution of 22nov89 Previous distribution 13sep89 (The Package consists of a) number of programs for converting various image formats to and from portable formats; plus some tools for manipulating the portable formats. The package is broken up into four parts (five parts if you count this one, the zeroth part). First is PBM, for bitmaps (1 bit per pixel). Then there is PGM, for grayscale images. Next is PPM, for full-color images. Last, there is PNM, which does content-independent manipulations on any of the three formats. PBM handles the following formats: Sun icon file reading writing Sun raster file reading writing X10 and X11 bitmap file reading writing MacPaint reading writing CMU window manager format reading writing MGR format reading writing Group 3 FAX reading writing X11 window dump file reading writing X10 window dump file reading Xerox doodle brushes reading GEM .img format reading PC paintbrush (.pcx) format reading PICT reading ASCII graphics writing HP LaserJet format writing GraphOn graphics writing BBN BitGraph graphics writing Printronix format writing PGM handles the following formats: TIFF reading Usenix FaceSaver file reading HIPS reading FITS reading writing PostScript "image" data reading raw grayscale bytes reading Encapsulated PostScript writing PPM handles the following formats: color Sun raster file reading writing GIF reading writing Amiga IFF ILBM reading writing color X11 window dump file reading writing color X10 window dump file reading MTV ray-tracer output reading QRT ray-tracer output reading TrueVision Targa file reading Img-whatnot file reading color Encapsulated PostScript writing -- S.P. van de Burgt PTT Research, Neher Labs PO Box 421, Leidschendam E-mail: SP_vdBurgt@pttrnl.nl the Netherlands

If you own a book, you can xerox the pages for your own use, but you can't start giving those copies away to others. That is not "fair use". Distributing reproductions without the written permission of the publisher is very illegal. That is exactly what the copyright says (just checked). In the case of the Internet, DEC is distributing these copies world wide. There is no "careful" legal way to do it. I'm no legal expert, but this one is interesting. My guess is that Mirage Editions will be "amused" that a big fat and rich corporation is distributing unlimited copies of their copyright protected works without permission. I intend to call them and the legal authorities and find out. Will post the results to the net. It should be entertaining :-). Tim tucker@smsc.Sony.COM
