Release notes for XPaint 2.6.0 ------------------------------ This version of XPaint is an interim release produced by Jean-Pierre Demailly (demailly@fourier.ujf-grenoble.fr). It is quite stable and corrects some minor problems of earlier releases 2.5.7-2.5.9. The official maintainer, Torsten Martinsen (torsten@image.dk) produced versions numbered 2.2.x to 2.5.7, and still maintains the main web page. The current versions are derived from XPaint 2.1.1, which was written by David Koblas. Please do NOT send bug reports etc. to David Koblas. To compile this program, you will need: - an ANSI C compiler (such as GCC), - the Xpm library, version 3.4c or later To compile with support for TIFF images, you must have the TIFF library, version 3.2 or later. To compile with support for JPEG images, you must have version 6 of the JPEG library from The Independent JPEG Group, released 2-Aug-95. Newer versions should also work. To compile with support for PNG images, you must have the PNG library, version 1.0.2 or higher. The TIFF/JPEG/PNG libraries can be downloaded from http://www.libtiff.org/ http://www.jpeg.org/public/jpeghomepage.htm http://www.libpng.org/ libpng itself requires zlib, which can be found at http://www.info-zip.org/pub/infozip/zlib/ There is a "Print" item in the file menu of painting windows. Printing is not directly dealt with by xpaint, but delegated to an external utility. John Bradley's xv program is convenient for this purpose. Other external utilities could be used instead, for instance Electric Eyes or the ImageMagick package. This can be parametrized in the app-default file with the print.label item. The proposed default is Canvas*menu*file*print.label: Print & XV...|xv -iconic -cmap & This means that the label will be "Print & XV..." and that the actual command used will be "xv -iconic -cmap" (the label and the actual command should be separated by a | ). The final & indicates that the printing utility will run in background. XPaint is known to have been successfully built on the following platforms: - Linux 2.0.18, XFree86 3.1.2, GCC 2.7.2 - Solaris 2.4, 2.5, 2.6 - SunOS 4.1, 4.1.4 - FreeBSD, NetBSD, BSD386 - DEC Alpha, native cc - AIX - SGI IRIX-6.2 - HP-UX A.09.05 A 9000/735, native cc Any feedback on problems is welcome, but remember to include the following in your bug report: - The version number of XPaint - The system you are using (e.g. 'Linux 1.3.14', 'Solaris 2.4') See 'INSTALL' for installation instructions. See 'Doc/CHANGES' for a list of changes relative to XPaint 2.1.1. See 'Doc/Operator.doc' for a description of XPaint internals. See 'Doc/sample.Xdefaults' for an example of setting resources for XPaint. See 'README.old' for the original README. See 'README.PNG' for notes on the PNG support. See 'TODO' for a list of possible improvements. See 'Doc/CHANGES' for a list of people who have contributed patches and bug reports. The most recent version of XPaint is always available from http://www.image.dk/~torsten/xpaint/index.html Thanks to the many beta testers who put up with the first buggy releases. KNOWN BUGS The 'Transparent Brush' tool does not work well on colour mapped visuals with 256 colours. The reasons are: 1) It is too slow. This could perhaps be fixed. 2) All entries in the colour map are used up in rather quickly. 3) The limited number of colours give rise to round-off errors when computing the new pixel colours. Undo/Redo exhibits some weirdness in certain circumstances. Selecting a region enables the 'Last Filter' menu item. The following causes a SIGSEGV (reported by Hans Dietmar Jäger <jagger@uni-paderborn.de>): open a file A open another file B do Image -> Change Size to file A, change Width, press TAB and leave the dialog open do Image -> Change Size to file B, change Width and leave the dialog open try to change Height by pressing TAB or clicking mouse-left in the Height field -Torsten Martinsen (torsten@image.dk) The following are new due and are related to the -visual flag: 1) DirectColor colormap is wrong. 2) Xaw3d only works in 8 bit mode -- has a problem with button = XtCreateManagedWidget(...) menu bar in menu.c in anything higher than 8 bits. 3) The smear tool fails in anything greater than 8 bit mode because XPutImage in smear() in brushOp.c is failing. Probably caused by depth mismatch somewhere in call to smear. -Scott D. Nelson (nelson18@llnl.gov), August 1997
