KETCindy Command Reference documents command-level usage for building and rendering geometric and mathematical figures with KETCindy. It explains initialization, file and folder handling, TEX output configuration, graphics package selection, and how to control axes, coordinate systems, colors, and plotting data. The reference also covers structured workflows for drawing primitives, tables, data processing, calculus and I/O, integration with other software, and animation-related features across KETCindy and KETCindy3D.

Examples Ketinit(); The work sub folder is set to "fig" in the folder of the cindy ﬁle. Ketinit(""); The work folder is set to the folder of the cindy ﬁle. Details This function should be written at the ﬁrst line on Draw slot page. In case of space ﬁgure (KeTCindy’s 3D-mode), write it in the initialization slot page ketlib. ⇒Command List Setﬁles Usage Setﬁles(ﬁlename) Description Generic function to set the name of texﬁle. Details Default ﬁle name is working Cinderella ﬁle name. Examples If working Cinderella ﬁle name is ”triangle.cdy” then default ﬁles name are ”triangle.tex”. By Setfiles("grav"); output ﬁles name are ”grav.tex”. ⇒Command List Setparent Usage Setparent(ﬁlename) Description Generic function to set the name of texﬁle by using the Parent push button. Details There is no default ﬁle name when we use the Figpdf() function and the Parent push button, so we have to deﬁne the name of output texﬁle. Examples If working Cinderella ﬁle name is ”triangle.cdy”, by Setparent("grav"); output ﬁles name are ”triangle.tex” and ”grav.tex”. PDF name is ”grav.pdf”. ⇒Command List Changework Usage Changework(name of pass) Description Generic function to change the working directory(folder) . Default working directory is ”ﬁg”. ⇒Command List Addpackage Usage Addpackage(list of style ﬁes) Description Generic function to add packages of TEX to the main ﬁle for previewing. Details Basically, ketpic,ketlayer,amsmath,amssymb,graphicx,color are used. Examples Addpackage(["[dvipdfmx]{media9}","[dvipdfmx]{animate}","ketmedia"]); ⇒Command List Usegraphics Usage Usegraphics(”pict2e”) Description This function changes the graphics package to "pict2e". Details The defaut package is "tpic". Examples Usegraphics("pict2e"); ⇒Command List 1.1.2 Drawing and deﬁning A

FAQs

What does Ketinit do and when should it be written?

Ketinit initializes KETCindy. It should be written at the first line on the Draw slot page (or in the initialization slot page ketlib for space figures/3D mode).

How can you control whether axes are drawn?

Use Addax(1/0): Addax(1) outputs axes in the TeX file (default) but not on the Euclidean view, while Addax(0) hides the coordinate axes.

How do you change the output graphics package?

Use Usegraphics("pict2e") to switch the graphics package to pict2e. The default package is "tpic".
