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 spec‐
ified 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 fore‐
ground 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 trans‐
parent) 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{...}.
-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 enforced. If the
file exists, it is silently overwritten.
-d, --daemonize
Run a separate, detached, klatexformula process and return imme‐
diately. All other options, like --latexinput, may still be
given. They will be forwared to the daemon process.
--outlinefonts [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
Convert embedded fonts in EPS and PDF to vector outlines (gs
with -dNOCACHE). Useful for exporting to eg. Adobe Illustrator.
--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 tempo‐
rary files. Defaults to a system-specific temporary directory
like "/tmp/".
--latex <latex executable>
--dvips <dvips executable>
--gs <gs executable>
--epstopdf <epstopdf executable>
Specifiy 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 KLatexFor‐
mula 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 klatexfor‐
mula 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 com‐
mand:
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.
Additional translation files and/or data can be provided to kla‐
texformula by specifying a list of Qt rcc files or directories
containing such files to import in the KLF_RESOURCES environment
variable. Separate the file names with ':' on unix/mac, or ';'
on windows. The default paths can be included with an empty sec‐
tion ('::') or leading or trailing ':'.
Please report any bugs and malfunctions to the author.

Have a lot of fun!
