[/latex] tags to mark chemfig code sections. we didn’t implement support chemfig commands directly in the text since one picture can be generated using long sequence of commands, there is no way for quicklatex to know where diagram starts/ends. read more » posted in quicklatex | leave a comment quicklatex: hackenbush diagram february 15, 2011 today i stumbled across tikz diagrams in math mode topic on tex.se . here is how quicklatex solves the task (example is taken from one of the answers in the thread): read more » posted in quicklatex | tagged diagram , hackenbush , quicklatex | leave a comment quicklatex: tikz-timing package february 9, 2011 latex package tikz-timing created by martin scharrer allows easy typing of timing diagrams (digital waveforms) in offline documents. with the aid of quicklatex tikz-timing diagrams can be used seamlessly in the wordpress blogs (or any other website). you can just paste tikz-timing commands directly in the text – quicklatex will compile them into images and embed in the published page. read more » posted in quicklatex | tagged quicklatex , tikz , tikz-timing | 2 comments quicklatex: laplace transformation symbols february 8, 2011 there are special commands for laplace-transformation symbols in trfsigns package (see the comprehensive symbol list , table 81, page 40): \laplace and \laplace . to use them with quicklatex, just include trfsigns in preamble (local or global), e.g: \[ [+preamble] \usepackage{trfsigns} [/preamble] f(t) \laplace F(s) \qquad F(s) \Laplace f(t) \] results in can you do that with other latex plugins for wordpress :-)? posted in quicklatex | tagged quicklatex , wordpress | 1 comment quicklatex: tikz graphics february 7, 2011 quicklatex is free online service which allows latex usage on the web pages. quicklatex supports tikz graphics since version 3.7.1. user can insert tikz code snippets directly on the page (in wordpress editor) between \begin{tikzpicture} ... \end{tikzpicture} commands. quicklatex will render it into image and place on the page. read more » posted in quicklatex | tagged quicklatex , tikz , wordpress | 2 comments how to: qextserialport for visual studio 2010 february 1, 2011 qextserialport is a nice library for serial port communication. it is based on c++ cross-platform qt framework and must have in the toolkit of dsp/embedded software developer. i’ve spent several hours trying to compile qextserialport for visual studio 2010 + qt 4.7.1. here is my recipe to success. we assume that qt is installed in c:\qt\4.7.1 (see how to compile qt 4.7 with visual studio 2010 for instructions). read more » posted in programming | tagged c++ , qextserialport , qt | 12 comments « older posts powered by wordpress with quicklatex . built on the thematic theme framework .
