NAME
klatexformula - GUI and CLI to generate images from LaTeX formulas
SYNOPSIS
klatexformula [OPTIONS] [filename1 [...]]
DESCRIPTION
KLatexFormula by Philippe Faist
An easy-to-use graphical application and command-line interface for generating images from
LaTeX equations.
Execution Modes:
klatexformula [filename1 [...]]
Opens klatexformula Graphical User Interface (GUI)
klatexformula [OPTIONS]
Performs actions required by [OPTIONS], and exits
klatexformula --interactive [OPTIONS] [filename1 [...]]
Opens the GUI and performs actions required by [OPTIONS]
If additional filename arguments are passed to the command line, they are
interpreted as library files to load into the library (only in interactive mode).
OPTIONS
-I, --interactive
Runs KLatexFormula in interactive mode with a full-featured graphical user
interface. This option is on by default, except if --input or --latexinput is
given.
-i, --input <file|->
Specifies a file to read latex input from.
-l, --latexinput <expr>
Specifies the LaTeX code of an equation to render.
-P, --paste-clipboard
-S, --paste-selection
Specifies that the LaTeX code should be pasted from the system clipboard or current
mouse selection. Works only in interactive mode.
-n, --noeval
Do not evaluate the LaTeX equation given, leave it to the user to click on the
"Evaluate" button. This option may only be used in interactive mode.
-B, --base64arg
Specifies that the argument to the option immediately following this one is encoded
in base64. For example:
klatexformula --base64arg --latexinput="YV4yK2JeMj1jXjI="
will use the latex code "a^2+b^2=c^2". This option can be specified more than once
on the command line, each time indicating that the argument to the immediately next
option is encoded in base64. This option can be useful when scripting, to avoid
the nuisance of having to escape latex code from the shell.
-o, --output <file|->
Specifies to write the output image (obtained from equation given by --input or
--latexinput) to <file> or standard output.
-F, --format <format>
Specifies the format the output should be written in. By default, the format is
guessed from file name extension and defaults to PNG.
-f, --fgcolor <'#xxxxxx'>
Specifies a color (in web #RRGGBB hex format) to use for foreground color. Don't
forget to escape the '#' to prevent the shell from interpreting it as a comment.
-b, --bgcolor <-|'#xxxxxx'>
Specifies a color (in web #RRGGBB hex format, or '-' for transparent) to use as
background color (defaults to transparent)
-X, --dpi <N>
Use N dots per inch (DPI) when converting latex output to image. Defaults to 1200
(high-resolution image).
-m, --mathmode <expression containing '...'>
Specifies which LaTeX math mode to use, if any. The argument to this option is any
string containing "...", which will be replaced by the equation itself. Defaults to
"\[ ... \]"
-p, --preamble <LaTeX code>
Any LaTeX code that will be inserted before \begin{document}. Useful for including
custom packages with \usepackage{...}.
-s, --userscript <user script>
Call a specific user script when running the backend. See the documentation in
libklfbackend for more information. The script must understand and respond to the
"--scriptinfo" option.
--want-pdf [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
If set, then PDF is also internally generated. This setting should be detected
automatically but you may adjust it if klatexformula guesses wrong.
--want-svg [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
If set, then SVG is also internally generated (via gs, note: not always available).
This setting should be detected automatically but you may adjust it if
klatexformula guesses wrong.
-q, --quiet [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
Disable console output of warnings and errors.
--redirect-debug <file>
Redirects debugging output to the given <file>. If the file name does not end with
.klfdebug, this suffix is automatically appended to the file name. If the file
exists, it is silently overwritten.
-d, --daemonize
Run a separate, detached, klatexformula process and return immediately. All other
options, like --latexinput, may still be given. They will be forwared to the daemon
process.
--skip-plugins
Obsolete. Since Klatexformula 4, no plugin system is available and plugins are
never loaded.
--calcepsbbox [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
Correct the bounding box of the output for characters that don't report a complete
or incorrect bounding box. (On by default.)
--nocalcepsbbox [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
Same as --calcepsbbox=<inverse of value given>
--outlinefonts [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
Convert embedded fonts in EPS and PDF to vector outlines (previously, gs pswrite
device with option -dNOCACHE; more recently, gs ps2write with -dNoOutputFonts).
Useful for exporting to eg. Inkscape or Adobe Illustrator.
--nooutlinefonts [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
Same as --outlinefonts=<inverse of value given>
--lborderoffset <N>
--tborderoffset <N>
--rborderoffset <N>
--bborderoffset <N>
Include a margin of N postscript points on left, top, right, or bottom margin
respectively.
--tempdir </path/to/temp/dir>
Specify the directory in which KLatexFormula will write temporary files. Defaults
to a system-specific temporary directory like "/tmp/".
--latex <latex executable>
--dvips <dvips executable>
--gs <gs executable>
--epstopdf <epstopdf executable>
[OBSOLETE: EPSTOPDF NO LONGER USED] Specify the executable for latex, dvips, gs or
epstopdf. By default, they are searched for in $PATH and in common system
directories.
-Q, --qtoption <qt-option>
Specify a Qt-specific option. For example, to launch KLatexFormula in Plastique GUI
style, use
klatexformula --qtoption="-style=Plastique"
Note that if <qt-option> begins with a '-', then it must be appended to the long
'--qtoption=' syntax with the equal sign.
-h, --help [<filename|&N>]
Display this help text and exit. If a file name is provided, the help message is
appended to that file. If the argument is "&<N>", then the help message is printed
in file descriptor N. (Reminder: N=1 for standard output 'stdout', N=2 for standard
error output 'stderr')
-V, --version [<filename|&N>][:<format>]
Display KLatexFormula version information and exit. The optional output argument
is handled as with --help, however it may also contain a version string format
preceded by a colon where %k, and %q and %% are respectively replaced by
klatexformula version, Qt version and a literal %.
EXAMPLES
Create an image named filename.png from the equation 'a^2+b^2=c^2':
klatexformula --latexinput 'a^2+b^2=c^2' --output filename.png
Open klatexformula window with equation 'f(x)=-2\,x', but don't evaluate it:
klatexformula -I --latexinput='f(x)=-2\,x' --noeval
Open klatexformula window and return immediately to shell command:
klatexformula -I --daemonize
Print help message, but to standard output instead of standard error output:
klatexformula --help='&1'
Notes:
When run in interactive mode, the newly evaluated equation is appended to
KLatexFormula's history.
When not run in interactive mode, no X11 server is needed.
Please report any bugs and malfunctions to the author.
