\subsection JKQTMathTextSuppoertedLaTeXFontPropsFonts Font Selection
These instructions are supported to select a font:
- \c \\textrm{...} \c \\mathrm{...} \c {\\rm...} \c {\\rmfamily...} \c \\mbox{...} : draw the contained text in normal upright roman font face \image html jkqtmathtext/jkqtmathtext_fonts.png
- \c \\textsf{...} \c \\mathsf{...} \c {\\sf...} \c {\\sffamily...} : draw the contained text in normal upright sans-serif font face \image html jkqtmathtext/jkqtmathtext_fonts.png
- \c \\textcal{...} \c \\mathcal{...} \c {\\cal...} : draw the contained text in caligraphic font face \image html jkqtmathtext/jkqtmathtext_cal.png
- \c \\textfrak{...} \c \\mathfrak{...} \c {\\frak...} : draw the contained text in fraktur font face \image html jkqtmathtext/jkqtmathtext_frak.png
- \c \\textscript{...} \c \\mathscript{...} \c {\\script...} : draw the contained text in script font face \image html jkqtmathtext/jkqtmathtext_script.png
- \c \\texttt{...} \c \\mathtt{...} \c {\\tt...} \c {\\ttshape...} : draw text in typewriter font \image html jkqtmathtext/jkqtmathtext_fonts.png
- \c \\userfont{font}{...} : draw text in a user-specific font, available on the system \image html jkqtmathtext/jkqtmathtext_userfont.png (generated by <code>default, \\userfont{Arial}{Arial}, \\userfont{Comic Sans MS}{Comic Sans MS}</code> )
Blackboard fonts are not widely available on target systems (viable fonts are e.g. <code>"Double Stroke", "CloisterOpenFace BT", "GoudyHandtooled BT", "Castellar", "MathJax_AMS", "Castellar Standard", "MathJax_AMS Standard", "Colonna MT"</code>). But the most important blackboard characters are usually available in the higher unicode codepoints of Fonts specialized for math (e.g. XIST, STIX, ASANA). Therefore JKQTMathText supports using these characters, or simulating a blackboard font in addition to using one of the fonts above. You can set that by setting JKQTMathText::setFontBlackboradMode() with one of the options from JKQTMathTextBlackboradDrawingMode:
- MTBBDMfontDirectly: use a blackboard font specified by JKQTMathText::setFontBlackboard() \image html jkqtmathtext/jkqtmathtext_bb_font_directly.png using \c JKQTMathText::setFontBlackboard("Castellar")
- MTBBDMsimulate: \image html jkqtmathtext/jkqtmathtext_bb_simulate.png using \c JKQTMathText::setFontBlackboard("Arial")
- MTBBDMunicodeCharactersOrFontDirectly: \image html jkqtmathtext/jkqtmathtext_bb_unicode_or_font_directly.png using \c JKQTMathText::setFontBlackboard("Castellar")
- MTBBDMunicodeCharactersOrSimulate: \image html jkqtmathtext/jkqtmathtext_bb_unicode_or_simulate.png using \c JKQTMathText::setFontBlackboard("Arial")
- \c \\textscript{...} \c \\mathscript{...} \c {\\script...} : draw the contained text in a script font face \image html jkqtmathtext/jkqtmathtext_fonts.png
.
\subsection JKQTMathTextSuppoertedLaTeXFontPropsFontSizes Font Sizes

JKQTMathText supports these instructions for font size in math mode:
- \c $\\displaystyle...$ switches back to the default font size
- \c $\\textstyle...$ switches back to the default font size
- \c $\\scriptstyle...$
- \c $\\scriptscriptstyle...$
.

\subsection JKQTMathTextSuppoertedLaTeXUnderlinesEtz Text Decoration: Underline, Overlines, Strikeout, ...
JKQTMathText supports several LaTeX instruction to decorate the text with underlines, overlines, etc:
- \c \\ul{...} , \c \\underline{...} , \c \\uline{...} \c \\underlined{...} : draw the text with underlining \image html jkqtmathtext/jkqtmathtext_ul.png
You can use all color names like (\c black , \c blue , \c yellow , \c transparent , ... see e.g. <a href="https://www.w3.org/TR/SVG11/types.html#ColorKeywords">https://www.w3.org/TR/SVG11/types.html#ColorKeywords</a> or <a href="https://en.wikipedia.org/wiki/Web_colors">https://en.wikipedia.org/wiki/Web_colors</a>) or a color defined via \c #RGB \c #RRGGBB \c #AARRGGBB \c #RRRGGGBBB \c #RRRRGGGGBBBB (where R,G,B are HEX-digits)
- \c \\colorbox{bordercolor}{...} : draw a colored box (see \ref JKQTMathTextSuppoertedLaTeXTextColor for accepted colors) \image html jkqtmathtext/jkqtmathtext_colorbox.png
- \c \\shaded{backgroundcolor}{...} : draw a filled box (see \ref JKQTMathTextSuppoertedLaTeXTextColor for accepted colors) \image html jkqtmathtext/jkqtmathtext_shaded.png
- \c \\snugshade{...} : draw text with a snug shade around it (see \ref JKQTMathTextSuppoertedLaTeXTextColor for accepted colors) \image html jkqtmathtext/jkqtmathtext_snugshade.png
- \c \\fcolorbox{bordercolor}{backgroundcolor}{...} : draw a colored, filled box (see \ref JKQTMathTextSuppoertedLaTeXTextColor for accepted colors) \image html jkqtmathtext/jkqtmathtext_fcolorbox.png
- \c \\colorbox{color}{...} : draw a colored box around text (see \ref JKQTMathTextSuppoertedLaTeXTextColor for accepted colors) \image html jkqtmathtext/jkqtmathtext_colorbox.png
\section JKQTMathTextSuppoertedLaTeXVerbatim Verbatim Text
Sometimes it is necessary to typeset text withou interpreting it as LaTeX markup. These instructions are implemented for that:
- <code>\\verb!...!</code>: interpret enclosed text between \c ! as verbose. Instead of \ ! you can choose ANY character! \image html jkqtmathtext/jkqtmathtext_verb.png generated by <code>\\verb!\\LaTeX{} is not pares inside \\verb~..~! outside {\\backslash}verb</code>
- <code>\\begin{verbatim}...\\end{verbatim}</code>: interpret enclosed multi-line text as verbatim. \image html jkqtmathtext/jkqtmathtext_verbatim.png
\endcode
- <code>\\begin{lstlisting}...\\end{lstlisting}</code>: actually menat for highlighted code, for now this is the same as \c \\begin{verbatim}...\\end{verbatim}. \image html jkqtmathtext/jkqtmathtext_lstlisting.png
- <code>\\begin{verbatim*}...\\end{verbatim*}</code>: interpret enclosed multi-line text as verbatim. Print with visible whitespace and tab characters \image html jkqtmathtext/jkqtmathtext_verbatimast.png
- \c \\alpha ... : display the according greek letter in italic style (see \ref jkqtmathtext_supportedlatexsymbols ) \image html jkqtmathtext/jkqtmathtext_greek.png
- \c \\upalpha ... : display the according upright greek letter. This letter is always upright, independent of the surrounding environment (see \ref jkqtmathtext_supportedlatexsymbols ) \image html jkqtmathtext/jkqtmathtext_upgreek.png
- \c \\textalpha ... : display the according greek letter with italic style defined by the current environment (i.e. italic in mathmode or inside \c \\textit{\\alpha} and upright in text mode). (see \ref jkqtmathtext_supportedlatexsymbols ) \image html jkqtmathtext/jkqtmathtext_textgreek.png
- \c \\charDECIMAL and \c \\char\"HEX and \c \\char\'OCTAL : draws a unicode character from its 32-bit codepoint \image html jkqtmathtext/jkqtmathtext_char.png (generated by <code>A: \\char65, circonflex: \\char\"109 accent: \\char\'351</code>)
- \c \\unicode{HEX} and \c \\usym{HEX} : draws a unicode character from its 32-bit codepoint \image html jkqtmathtext/jkqtmathtext_unicode.png (generated by <code>star: \\unicode{2605}, circonflex: \\unicode{109} emoticons: \\usym{1F440} \\usym{1F929}</code>)
- \c \\utfeight{HEX} : draws a unicode character from its UTF-8 encoding \image html jkqtmathtext/jkqtmathtext_utf8.png (generated by <code>star: \\utfeight{e29885} emoticons \\utfeight{F09F9881} \\utfeight{f09f98bb}</code>)
- The usual LaTeX-accent commands are also implemented here and work as expected in text-mode, provided the matching unicode characters are available in the current font.
\image html jkqtmathtext/jkqtmathtext_textaccents.png
- In math-mode the text-accent commands do not work. here you have to use the math-mode commands:
\image html jkqtmathtext/jkqtmathtext_mathaccents.png
- \c \\sum \c \\prod \c \\int ... : plot special symbol (see \ref jkqtmathtext_supportedlatexsymbols ). Note that depending on the fontEncoding the available
- \c \\limits , \c \\nolimits : Several special symbols, like \c \\sum , \c \\lim , ... cause sub-/superscripts to be positioned below/above the symbol, not besides it. This behaviour can be altered by using \c \\limits and \c \\nolimits : \image html jkqtmathtext/jkqtmathtext_limits.png
- <code>$\\substack[lrc]{...\\\\...}$</code> allows to e.g. subset several lines below a \c \\sum using \c \\sum\\limits_\\substack{a<5\\\\b<100}: \image html jkqtmathtext/jkqtmathtext_substack.png
- <code>$\\lsubstack{...\\\\...}$</code> \image html jkqtmathtext/jkqtmathtext_lsubstack.png
- <code>$\\rsubstack{...\\\\...}$</code> \image html jkqtmathtext/jkqtmathtext_rsubstack.png
- You can use \c \\left. or \c \\right. to have only right or only left brace , \image html jkqtmathtext/jkqtmathtext_brace_dot.png generated by <code>{\\backslash}left.: $\\left. a\\cdot x^2\\right)$\\ \\ \\ \\ \\ {\\backslash}right.: $\\left( a\\cdot x^2\\right.$</code>
\image html jkqtmathtext/jkqtmathtext_brace_bigfamily.png generated by <code> $\\Biggl\\langle\\biggl\\{\\Bigl[\\bigl( r^{123}\\bigr)\\Bigr]\\biggr\\}\\Biggr\\rangle$</code>
