KLATEXFORMULA(1) User Commands KLATEXFORMULA(1) NAME klatexformula - manual page for klatexformula 4.0.0 SYNOPSIS klatexformula [OPTIONS] [filename1 [...]] DESCRIPTION KLatexFormula by Philippe Faist An easy-to-use graphical application and command-line interface for gener- ating 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 graphi- cal 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 clip- board 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 in- teractive 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 in- terpreting it as a comment. -b, --bgcolor <-|'#xxxxxx'> Specifies a color (in web #RRGGBB hex format, or '-' for transpar- ent) to use as background color (defaults to transparent) -X, --dpi <N> Use N dots per inch (DPI) when converting latex output to image. De- faults 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 docu- mentation in libklfbackend for more information. The script must un- derstand 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 al- ways 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 immedi- ately. 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 re- port 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 (previ- ously, 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 bot- tom 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] Specifiy the executable for la- tex, 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 con- tain a version string format preceded by a colon where %k, and %q and %% are respectively replaced by klatexformula version, Qt ver- sion 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 ap- pended to KLatexFormula's history. When not run in interactive mode, no X11 server is needed. Please report any bugs and malfunctions to the author. More information is available on http://klatexformula.sourceforge.net/. Have a lot of fun! klatexformula 4.0.0 August 2026 KLATEXFORMULA(1)
