SYNOPSIS

9       klatexformula [OPTIONS] [filename1 [...]]
10

DESCRIPTION

12       KLatexFormula by Philippe Faist
13
14       An  easy-to-use  graphical  application  and command-line interface for
15       generating images from LaTeX equations.
16
17   Execution Modes:
18              klatexformula [filename1 [...]]
19
20              Opens klatexformula Graphical User Interface (GUI)
21
22              klatexformula [OPTIONS]
23
24              Performs actions required by [OPTIONS], and exits
25
26              klatexformula --interactive [OPTIONS] [filename1 [...]]
27
28              Opens the GUI and performs actions required by [OPTIONS]
29
30              If additional filename arguments are passed to the command line,
31              they  are  interpreted as library files to load into the library
32              (only in interactive mode).
33

OPTIONS

35       -I, --interactive
36
37              Runs KLatexFormula in  interactive  mode  with  a  full-featured
38              graphical  user  interface. This option is on by default, except
39              if --input or --latexinput is given.
40
41       -i, --input <file|->
42
43              Specifies a file to read latex input from.
44
45       -l, --latexinput <expr>
46
47              Specifies the LaTeX code of an equation to render.
48
49       -P, --paste-clipboard
50
51       -S, --paste-selection
52
53              Specifies that the LaTeX code should be pasted from  the  system
54              clipboard  or current mouse selection. Works only in interactive
55              mode.
56
57       -n, --noeval
58
59              Do not evaluate the LaTeX equation given, leave it to  the  user
60              to  click on the "Evaluate" button. This option may only be used
61              in interactive mode.
62
63       -B, --base64arg
64
65              Specifies that the argument to the option immediately  following
66              this one is encoded in base64. For example:
67
68              klatexformula --base64arg --latexinput="YV4yK2JeMj1jXjI="
69
70              will use the latex code "a^2+b^2=c^2".  This option can be spec‐
71              ified more than once on the command line, each  time  indicating
72              that  the  argument to the immediately next option is encoded in
73              base64.  This option can be useful when scripting, to avoid  the
74              nuisance of having to escape latex code from the shell.
75
76       -o, --output <file|->
77
78              Specifies  to  write  the  output  image (obtained from equation
79              given by --input or --latexinput) to <file> or standard output.
80
81       -F, --format <format>
82
83              Specifies the  format  the  output  should  be  written  in.  By
84              default,  the  format  is  guessed  from file name extension and
85              defaults to PNG.
86
87       -f, --fgcolor <'#xxxxxx'>
88
89              Specifies a color (in web #RRGGBB hex format) to use  for  fore‐
90              ground  color.   Don't  forget  to escape the '#' to prevent the
91              shell from interpreting it as a comment.
92
93       -b, --bgcolor <-|'#xxxxxx'>
94
95              Specifies a color (in web #RRGGBB hex format, or '-' for  trans‐
96              parent) to use as background color (defaults to transparent)
97
98       -X, --dpi <N>
99
100              Use N dots per inch (DPI) when converting latex output to image.
101              Defaults to 1200 (high-resolution image).
102
103       -m, --mathmode <expression containing '...'>
104
105              Specifies which LaTeX math mode to use, if any. The argument  to
106              this  option  is  any  string  containing  "...",  which will be
107              replaced by the equation itself. Defaults to "\[ ... \]"
108
109       -p, --preamble <LaTeX code>
110
111              Any LaTeX code that will be  inserted  before  \begin{document}.
112              Useful for including custom packages with \usepackage{...}.
113
114       -s, --userscript <user script>
115
116              Call  a  specific  user script when running the backend. See the
117              documentation in libklfbackend for more information. The  script
118              must understand and respond to the "--scriptinfo" option.
119
120       --want-pdf [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
121
122              If  set,  then  PDF  is  also internally generated. This setting
123              should be detected automatically but you may adjust it  if  kla‐
124              texformula guesses wrong.
125
126       --want-svg [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
127
128              If set, then SVG is also internally generated (via gs, note: not
129              always available). This setting should be detected automatically
130              but you may adjust it if klatexformula guesses wrong.
131
132       -q, --quiet [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
133
134              Disable console output of warnings and errors.
135
136       --redirect-debug <file>
137
138              Redirects debugging output to the given <file>. If the file name
139              does not  end  with  .klfdebug,  this  suffix  is  automatically
140              appended  to  the file name.  If the file exists, it is silently
141              overwritten.
142
143       -d, --daemonize
144
145              Run a separate, detached, klatexformula process and return imme‐
146              diately.  All  other  options,  like  --latexinput, may still be
147              given. They will be forwared to the daemon process.
148
149       --skip-plugins
150
151              Obsolete. Since Klatexformula 4, no plugin system  is  available
152              and plugins are never loaded.
153
154       --calcepsbbox [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
155
156              Correct the bounding box of the output for characters that don't
157              report a complete or incorrect bounding box. (On by default.)
158
159       --nocalcepsbbox [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
160
161              Same as --calcepsbbox=<inverse of value given>
162
163       --outlinefonts [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
164
165              Convert embedded fonts in EPS and PDF to vector outlines (previ‐
166              ously,  gs  pswrite device with option -dNOCACHE; more recently,
167              gs ps2write with -dNoOutputFonts).  Useful for exporting to  eg.
168              Inkscape or Adobe Illustrator.
169
170       --nooutlinefonts [<ON|Y[ES]|T[RUE]|1 or OFF|N[O]|F[ALSE]|0>]
171
172              Same as --outlinefonts=<inverse of value given>
173
174       --lborderoffset <N>
175
176       --tborderoffset <N>
177
178       --rborderoffset <N>
179
180       --bborderoffset <N>
181
182              Include  a margin of N postscript points on left, top, right, or
183              bottom margin respectively.
184
185       --tempdir </path/to/temp/dir>
186
187              Specify the directory in which KLatexFormula will  write  tempo‐
188              rary  files.   Defaults to a system-specific temporary directory
189              like "/tmp/".
190
191       --latex <latex executable>
192
193       --dvips <dvips executable>
194
195       --gs <gs executable>
196
197       --epstopdf <epstopdf executable>
198
199              [OBSOLETE: EPSTOPDF NO LONGER USED] Specifiy the executable  for
200              latex,  dvips, gs or epstopdf. By default, they are searched for
201              in $PATH and in common system directories.
202
203       -Q, --qtoption <qt-option>
204
205              Specify a Qt-specific option. For example, to launch  KLatexFor‐
206              mula in Plastique GUI style, use
207
208              klatexformula --qtoption="-style=Plastique"
209
210              Note  that  if  <qt-option>  begins  with a '-', then it must be
211              appended to the long '--qtoption=' syntax with the equal sign.
212
213       -h, --help [<filename|&N>]
214
215              Display this help text and exit.  If a file  name  is  provided,
216              the  help  message  is appended to that file. If the argument is
217              "&<N>", then the help message is printed in file  descriptor  N.
218              (Reminder:  N=1  for  standard output 'stdout', N=2 for standard
219              error output 'stderr')
220
221       -V, --version [<filename|&N>][:<format>]
222
223              Display  KLatexFormula  version  information  and   exit.    The
224              optional  output  argument is handled as with --help, however it
225              may also contain a version string format  preceded  by  a  colon
226              where  %k, and %q and %% are respectively replaced by klatexfor‐
227              mula version, Qt version and a literal %.
228

EXAMPLES

230              Create  an  image   named   filename.png   from   the   equation
231              'a^2+b^2=c^2':
232
233              klatexformula --latexinput 'a^2+b^2=c^2' --output filename.png
234
235              Open  klatexformula window with equation 'f(x)=-2\,x', but don't
236              evaluate it:
237
238              klatexformula -I --latexinput='f(x)=-2\,x' --noeval
239
240              Open klatexformula window and return immediately to  shell  com‐
241              mand:
242
243              klatexformula -I --daemonize
244
245              Print  help  message, but to standard output instead of standard
246              error output:
247
248              klatexformula --help='&1'
249
250   Notes:
251              When run in interactive mode, the newly  evaluated  equation  is
252              appended to KLatexFormula's history.
253
254              When not run in interactive mode, no X11 server is needed.
