kdvi 0.4 - Alpha release
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This is a port of xdvik version 18f by many authors (see files AUTHORS)
|
||||
to the K Desktop Environment. kdvi is used to view TeX DVI files. It is
|
||||
a replacement of xdvi from tetex-distribution and uses the kpathsea
|
||||
library to find the needed pk-font files. If you have tetex you should be
|
||||
able to run kdvi. It requires also Ghostcript to render any postscript
|
||||
specials in dvi files. kdvi uses the Qt toolkit.
|
||||
|
||||
This version is quite useable.
|
||||
|
||||
|
||||
Note. The make step currently runs configure in the kpathsea subdirectory.
|
||||
I may eliminate this in a later version.
|
||||
|
||||
If xdvi from tetex works for you then so should kdvi.
|
||||
However, it has only been tested on Linux. The support for handling the xdvi
|
||||
command line arguments and X application defaults is missing (partly replaced
|
||||
by KConfig, see below and online help).
|
||||
Postscript special handling only supported with Ghostscript.
|
||||
|
||||
|
||||
CONFIGURATION
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
Version 0.4 can be configured through dialogs.
|
||||
|
||||
Before giving kdvi a file to open you should set the following entries in Fonts
|
||||
page of Preferences:
|
||||
|
||||
o Resolution Set this to the base resolution of your printer if you
|
||||
have already PK-fonts for printer available.
|
||||
|
||||
o MetafontMode This you can set to match the definition of your printer or
|
||||
use the default mode '/'.
|
||||
|
||||
It is necessary to set the Resolution as required by your TeX installation.
|
||||
(tetex stores this usually in /usr/lib/texmf/texmf/xdvi/XDvi). MetafontMode is
|
||||
needed when you want to enable automatic pk-font generation (menu option).
|
||||
See online help for more info.
|
||||
|
||||
These variables should preferably be set in the system wide configuration file.
|
||||
The system administrator can set the proper values ( and other settings as
|
||||
desired ) with kdvi and copy the config file ~/.kde/share/config/kdvirc
|
||||
to $KDEDIR/share/config/kdvirc.
|
||||
|
||||
You can also specify the paths where your pk-fonts are located, if
|
||||
kdvi does not find them automatically, by setting entry 'PK Font Path' to
|
||||
the list of directories to be searched:
|
||||
|
||||
/var/lib/texmf/fonts/pk/ljfour/:/some/other/place
|
||||
|
||||
You can make kdvi search recursively by adding an extra / at the end of
|
||||
directory name:
|
||||
|
||||
/var/lib/texmf/fonts//
|
||||
|
||||
This works like xdvi's XDVIFONTS environment variable.
|
||||
There is also good (gnu info) documentation available for the kpathsea library
|
||||
that kdvi uses for font searching.
|
||||
|
||||
USAGE:
|
||||
~~~~~~
|
||||
|
||||
The dvi viewer may be started using a file name to display a file, e.g:
|
||||
|
||||
kdvi somepath/paper.dvi
|
||||
|
||||
or without a file name as
|
||||
|
||||
kdvi
|
||||
|
||||
kdvi will then allow a file to be opened from a dialog or when dropped from
|
||||
file manager (konqueror).
|
||||
|
||||
The usual parameters handled by Qt should also work:
|
||||
|
||||
kdvi -style windows -display :0 -geometry 400x400+0+0
|
||||
|
||||

CHANGES:
|
||||
~~~~~~~~
|
||||
|
||||
Version 0.4
|
||||
~~~~~~~~~~~
|
||||
|
||||
- Antialiased PostScript specials
|
||||
|
||||
- Support session management
|
||||
|
||||
- Changes menu accelerators according to KKeyConfig settings.
|
||||
Shortcuts should follow KDE standard.
|
||||
|
||||
- Statusbar shows the coordinates of a clicked point in millimeters.
|
||||
|
||||
- Changed build to use automake (not for kpathsea yet)
|
||||
|
||||
- Better print dialog + print setup dialog. Support for dvilj4 and dvips.
|
||||
|
||||
- Automatic reload when dvi file is updated
|
||||
|
||||
- Uses KToolbar, KStatusbar and KTopLevelWidget
|
||||
|
||||
- Command line option '-caption'
|
||||
|
||||
- Uses KIconLoader and KDebugDialog
|
||||
|
||||
- Partial support for translations
|
||||
|
||||
- Many bug fixes
|
||||
|
||||
- Internal changes
|
||||
|
||||
- Miscellanous other changes
|
||||
|
||||
|
||||
Version 0.3
|
||||
~~~~~~~~~~~
|
||||
|
||||
- Preferences dialog
|
||||
|
||||
- Paper type selectable
|
||||
|
||||
- Configurable key bindings with kkeyconfig (first cut)
|
||||
|
||||
- Works with kdisplay
|
||||
|
||||
- Uses KMsgBox dialogs
|
||||
|
||||
- Sticky popup menus
|
||||
|
||||
- Needs Qt 1.2 ( check marks in menus )
|
||||
|
||||
- Many bug fixes
|
||||
|
||||
- More KDE conforming
|
||||
|
||||
|
||||
Version 0.2
|
||||
~~~~~~~~~~~
|
||||
|
||||
- Configuration file uses different variables
|
||||
|
||||
- Status bar and vertical toolbar
|
||||
|
||||
- Added a page list for selecting the current page and marking pages
|
||||
for printing.
|
||||
|
||||
- Initial print dialog. Does not support printing of marked pages that
|
||||
have page numbers different from the sequence number (pages are not
|
||||
numbered as 1,2,3...). Requires dvips for converting dvi to PostScript,
|
||||
gv for previewing PS and mpage for printing multiple pages per sheet.
|
||||
(These should be replaced by kprogs.)
|
||||
|
||||
- A scroller widget that can also select the next or previous page.
|
||||
|
||||
- Support for new TeX config file format of tetex 4
|
||||
|
||||
- File drops accepted (local files only)
|
||||
|
||||
- Many bug fixes
|
||||
|
||||
- Builds using configure
|
||||
|
||||
- Screen updating reduced and scrolling made smoother.
|
||||
This results in kdvi allocating huge amounts of memory when using large
|
||||
magnifications.
|
||||
|
||||
Version 0.1
|
||||
~~~~~~~~~~~
|
||||
|
||||
First release. Should be quite usable, with some problems on error handling
|
||||
(bad dvi etc.) and postscript special handling. All enabled menu entries and
|
||||
toolbar buttons are operational, many keybindings are available (see help)
|
||||
allthough probably not KDE-conformant (expect changes).
