This allow people + to store additional data related to a pixmap. See documentation for + detail. + - sxpm supports the new option '-c' to use a private colormap. This is + useful when displaying pixmaps using a lot of colors. + - sxpm supports the new option '-v' (verbose) to get possible + extensions print out on standard error. + + ENHANCEMENTS: + - most of the code has been reworked to be improved and thus almost + every function is faster. It takes less than 6 seconds of real time on + a sun4 to display, with sxpm, a 487x635 pixmap using 213 colors, while + it takes 32 seconds with the old library! It takes 18 seconds to + display a 1279x1023 screen dump using 14 colors while xwud takes 10 + seconds. + Of course performance improvements are not always that great, they + depend on the size and number of colors but I'm sure everybody will + appreciate ;-) + I know how to improve it more but this will require changes in the + architecture so this is not for now. Some optimizations have been + contributed by gregor@kafka.saic.com (gregg hanna) and + jnc@csl.biosci.arizona.edu (John N. Calley). + - the Imakefile is modified to let you install sxpm - Rainer Klute + <klute@irb.informatik.uni-dortmund.de> + - xpmP.h declares popen for Sequent platforms - Clinton Jeffery + <cjeffery@cs.arizona.edu> + - XpmWriteFileFromImage/Pixmap rather than truncating the pixmap name + to the first dot changes dots to underscores to get a valid C syntax + name. + + + BUGS CORRECTED: + - there was a bug in the image creation function for some 24 bits + displays. It is fixed. + - allocated color pixels are now freed when an error occurs - + nusser@dec1.wu-wien.ac.at (Stefan Nusser) + + CHANGES TO THE DOC: + - the documentation describes the new XpmExtension structure and how + to use it with read and write functions. + +3.1 (92/02/03) + + ENHANCEMENTS: + - sxpm now have more standard options (mainly suggested by + Rainer Sinkwitz <sinkwitz@ifi.unizh.ch>): + + Usage: sxpm [options...] + Where options are: + + [-d host:display] Display to connect to. + [-g geom] Geometry of window. + [-hints] Set ResizeInc for window. + [-icon filename] Set pixmap for iconWindow. + [-s symbol_name color_name] Overwrite color defaults. + [-p symbol_name pixel_value] Overwrite color defaults. + [-plaid] Read the included plaid pixmap. + [filename] Read from file 'filename', and from + standard input if 'filename' is '-'. + [-o filename] Write to file 'filename', and to standard + output if 'filename' is '-'. + [-nod] Don't display in window. + [-rgb filename] Search color names in the rgb text file + 'filename'. + + if no input is specified sxpm reads from stdandard input. + + + - Xpm functions and Ppm converters now deal with multiword colornames. + patches from Rainer Sinkwitz <sinkwitz@ifi.unizh.ch>. + + +3.0 (91/10/03) + + Functions name and defines have been modified again (sorry for that) + as follows: + + XpmReadPixmapFile XpmReadFileToPixmap + XpmWritePixmapFile XpmWriteFileFromPixmap + + XpmPixmapColorError XpmColorError + XpmPixmapSuccess XpmSuccess + XpmPixmapOpenFailed XpmOpenFailed + XpmPixmapFileInvalid XpmFileInvalid + XpmPixmapNoMemory XpmNoMemory + XpmPixmapColorFailed XpmColorFailed + + To update code using Xpm you can use the included shell script called + rename with the sed commands files name-3.0b-3.0c and name-3.0c-3.0. + Old names still valid though. + + NEW FEATURES: + - four new functions to work with images instead of pixmaps: + + XpmReadFileToImage + XpmWriteFileFromImage + XpmCreateImageFromData + XpmCreateDataFromImage + + ENHANCEMENTS: + Algorithms to create and scan images and pixmaps are based on the + MIT's R5 code, thus they are much cleaner than old ones and should + avoid any problem with any visual (yes, I trust MIT folks :-) + + BUGS CORRECTED: + Imakefile use INCDIR instead of ROOTDIR. + + CHANGES TO THE DOC: + - the documentation presents the four new functions. + +3.0c (91/09/18) + + In answer to request of people functions, types and defines names have + been changed as follows: + + XCreatePixmapFromData XpmCreatePixmapFromData + XCreateDataFromPixmap XpmCreateDataFromPixmap + XReadPixmapFile XpmReadPixmapFile + XWritePixmapFile XpmWritePixmapFile + XFreeXpmAttributes XpmFreeAttributes + + PixmapColorError XpmPixmapColorError + PixmapSuccess XpmPixmapSuccess + PixmapOpenFailed XpmPixmapOpenFailed + PixmapFileInvalid XpmPixmapFileInvalid + PixmapNoMemory XpmPixmapNoMemory + PixmapColorFailed XpmPixmapColorFailed + + ColorSymbol XpmColorSymbol + + Generally speaking every public name begins with 'Xpm' and every + private one with 'xpm'. This should avoid any possible conflict. + + Some files have also be renamed accordingly. + + NEW FEATURES: + - support for VMS and two new options for sxpm: icon and hints (see + manual for details) Richard Hess <rhess%pleione%cimshop@uunet.UU.NET> + - DEFINES in Imakefile and Makefile.noXtree allows you to set the + following: + + ZPIPE for un/compressing piped feature (default is on) + NEED_STRCASECMP for system which doesn't provide one (default + is off) + + - xpmtoppm.c has is own strstr function which is used if NEED_STRSTR + is defined when compiling - Hugues.Leroy@irisa.fr (Hugues Leroy). + + BUGS CORRECTED: + - many bugs have been fixed, especially for ansi compilers - + Doyle C. Davidson (doyle@doyled.b23b.ingr.com) and + Clifford D. Morrison (cdm%bigdaddy%edsr@uunet.UU.NET) + - parser is again a little more improved + +3.0b (91/09/12) + + This is a complete new version with a new API and where files and + structures have been renamed. So this should be taken as a new + starting release. + This release should be quickly followed by the 3.0 because I'm planning + to send it for X11R5 contrib which ends October 5th. + + NEW FEATURES: + - support for transparent color. + - support for hotspot. + - a new function: XCreateDataFromPixmap to create an XPM data from a + pixmap in order to be able to create a new pixmap from this data using + the XCreatePixmapFromData function later on. + - a new structure: XpmAttributes which replace the XpmInfo structure + and which leads to a much simpler API with less arguments. + - arguments such as visual, colormap and depth are optionnal, default + values are taken if omitted. + - parsing and allocating color failures don't simply break anymore. If + another default color can be found it is used and a PixmapColorError + is returned. In case no color can be found then it breaks and returns + PixmapColorFailed. + - for this reason the ErrorStatus codes are redefined as follows: + + null if full success + positive if partial success + negative if failure + + with: + #define PixmapColorError 1 + #define PixmapSuccess 0 + #define PixmapOpenFailed -1 + #define PixmapFileInvalid -2 + #define PixmapNoMemory -3 + #define PixmapColorFailed -4 + + - sxpm prints out a warning when a requested color could not be parsed + or alloc'ed, and an error when none has been found. + - sxpm handles pixmap with transparent color. For this purpose the + plaid_mask.xpm is added to the distribution. + + BUGS CORRECTED: + - I've again improved the memory management. + - the parser is also improved. + - when writting a pixmap to a file the variable name could be + "plaid.xpm" which is not valid in C. Now the extension name is cut off + to give "plaid" as variable name. + - reading multiple words colornames such as "peach puff" where leading + to non readable Xpm files. They are now skipped to have only single + word colorname. Lionel Mallet (mallet@ipvpel.unipv.it). + - parser was triggered by the "/" character inside string. + Doyle C. Davidson (doyle@doyled.b23b.ingr.com). This is corrected. + - sxpm maps the window only if the option "-nod" is not selected. + + CHANGES TO THE DOC: + - the documentation presents the new API and features. + +3.0a (91/04/10) + + This is an alpha version because it supports the new version of XPM, + but the library interface is still the same. Indeed it will change in + future release to get rid of obsolete stuff such as the type argument + of the XWritePixmapFile function. + + ******************************* WARNING ********************************* + The format is not anymore XPM2, it is XPM version 3 which is XPM2 + limited to the C syntax with the key word "XPM" in place of "XPM2 C". + The interface library has not changed yet but the type argument of + XWritePixmapFile and the type member of XpmInfo are not used anymore. + Meanwhile the library which is now called libXpm.a is backward + compatible as XPM2 files can be read. But the XWritePixmapFile + function only writes out XPM version 3 files. + ************************************************************************* + + NEW FEATURES: + - the library doesn't use global variables anymore, thus it should be + able to share it. + - sxpm has been rewritten on top of Xt, it can be used to convert + files from XPM2 to XPM version 3. + - xpm1to2c.perl has been upgraded to the new XPM version and renamed + as xpm1to3.perl + - ppmtoxpm2.c and ppmtoxpm2.1 have been upgraded too and renamed + ppmtoxpm.c and ppmtoxpm.1. In addition the xpmtoppm.c and xpmtoppm.1 + of the pbmplus package have been upgraded too. xpmtoppm can thus + convert XPM version 1 and 3 to a portable pixmap. These files should + replace the original ones which are part of the pbmplus package. See + the ppm.README file for more details. + - the library contains RCS variables which allows you to get revision + numbers with ident (which is part of the RCS package). The Id number + is an internal rcs number for my eyes only. The official one is found + in Version. + + BUGS CORRECTED: + - the memory management has been much improved in order to avoid + memory leaks. + - the XImage building algorythm has been changed to support correctly + different visual depths. There is special code to handle depths 1, 4, + 6, 8, 24, and 32 to build the image and send it in one whack, and + other depths are supported by building the image with XPutPixel which + is slow but sure. + - similar algorithms are used to read pixmaps and write them out. + + CHANGES TO THE DOC: + - the documentation presents the new XPM format. + + +2.8 (90/12/19) + + ******************************* WARNING ********************************* + Since the last release two structures have been modified and have now + bigger sizes, so ANY CODE USING THE libXPM2 NEEDS TO BE RECOMPILED. + ************************************************************************* + + NEW FEATURES: + - the ColorSymbol struct contains the new member 'pixel' which allow + to override default colors by giving a pixel value (in such a case + symbol value must be set to NULL), + - the XpmInfo struct contains the new member 'rgb_fname' in which one + can specify an rgb text file name while writing a pixmap with the + XWritePixmapFile function (otherwise this member should be set to + NULL). This way colorname will be searched and written out if found + instead of the RGB value, + - Imakefile originally provided by stolcke@ICSI.Berkeley.EDU, + - the old Makefile is now distributed as Makefile.noXtree and presents + install targets, + - the demo application is renamed sxpm (Show XPM), creates a window of + the size of the pixmap if no geometry is specified, prints out + messages instead of status when an error occurs, handles the new + option -p for overriding colors by giving a pixel value (not really + useful but is just here to show this new feature), handles the new + option -rgb for specifying an rgb text file, and ends on + keypress as buttonpress, + - defines for SYSV have been provided by Paul Breslaw + <paul@mecazh.uucp>, + - the distribution includes a new directory called converters which + contains xpm1to2 and xpm1to2c perl converters and a ppmtoxpm2 + converter provided by Paul Breslaw who upgraded the original ppmtoxpm + written by Mark W. Snitily <mark@zok.uucp>. + + CHANGES TO THE DOC: + - this file is created and will give old users a quick reference to + changes made from one release to the next one, + - documentation is changed to present the new ColorSymbol structure + and the way to override colors by giving a pixel value, and to present + the new XpmInfo structure and how to use it, + - a man page for sxpm is added to the distrib, + - the README file talks about sxpm and no more demo, and have + reference to the different converters. + +2.7 (90/11/12) + + NEW FEATURES: + - XReadPixmapFile reads from stdin if filename is NULL, + - XWritePixmapFile writes to stdin if filename is NULL, + - the demo application handles the new option -nod for no displaying + the pixmap in a window (useful when used as converter). + + CHANGES TO THE DOC: + - documentation about the new feature. + +2.6 (90/10/29) + + NEW FEATURES: + - from nazgul@alphalpha.com (Kee Hinckley): changes to make the + library usable as C++ code, and on Apollo without any warning. + + BUGS CORRECTED: + - from nazgul@alphalpha.com (Kee Hinckley): the xpm include files was + declaring XWritePixmapFile as taking in arg a Pixmap pointer instead + of a Pixmap. + +2.5 (90/10/17) + + BUGS CORRECTED: + - XWritePixmapFile was not closing the file while ending normaly. + +2.4 (90/09/06) + + NEW FEATURES: + - XReadPixmapFile reads from a piped uncompress if the given filename + ends by .Z or if filename.Z exists, + - XWritePixmapFile writes to a piped compress if the given filename + ends by .Z. + + BUGS CORRECTED: + - demo now deals with window manager. + + CHANGES TO THE DOC: + - documentation about compressed files management. + +2.3 (90/08/30) + + BUGS CORRECTED: + - handle monochrom display correctly, + - comments can be empty. + +2.2 (90/08/27) + + BUGS CORRECTED: + - when reading some invalid free was dumping core on some machine. + +2.1 (90/08/24) + + First distribution of XPM2. + |
