Getting the pointsDrawing DotsSimple LinesEnds of Lines1. Graphics with PSTricksBent Lines and PolygonsSimple CurvesL A T E X has only limited drawing capabilities, while PostScript is a page descriptionlanguage which has a rich set of drawing commands; and thereare programs (such as dvips) which translate the dvi output to PostScript.So, the natural question is whether one can include PostScript code in a T E Xsource file itself for programs such as dvips to process after the T E X compilation?This is the idea behind the PSTricks package of Timothy van Zandt.The beauty of it is one need not know PostScript to use it—the necessaryPostScript code can be generated by T E X macros defined in the package.Online L A T E X TutorialPart II – Graphicsc○2002, The Indian T E X Users GroupThis document is generated by PDFT E X withhyperref, pstricks, pdftricks and pdfscreenpackages in an intel PC running GNU/LINUXand is released under LPPLThe Indian T E X Users GroupFloor iii, sjp Buildings, Cotton HillsTrivandrum 695014, indiahttp://www.tug.org.in
1.1. Getting the pointsAny picture is drawn by stringing together appropriate points. How do wespecify the points we need? We’ve a method of specifying each point ina plane using a pair of numbers, thanks to the 17 th century French mathematiciansPierre de Fermat and René Descartes. The method is to fix apair of perpendicular lines (called axes) and label each point with the numbersrepresenting its distance from these two points (called coordinates) asshown in the figure below:Graphics with PSTricksGetting the pointsDrawing DotsSimple LinesEnds of LinesBent Lines and PolygonsSimple Curves(0,0)3 unit(1.5,0.5)(3,2)2 unitOnline L A T E X TutorialPart II – GraphicsNote that the meeting point of the axes (called the origin) has coordinates(0,0). In order to associate each pair of numbers with a unique point, wemake the convention that horizontal distances to the left of the origin andvertical distances below the origin are negative as illustrated below:c○2002, The Indian T E X Users GroupThis document is generated by PDFT E X withhyperref, pstricks, pdftricks and pdfscreenpackages in an intel PC running GNU/LINUXand is released under LPPLThe Indian T E X Users GroupFloor iii, sjp Buildings, Cotton HillsTrivandrum 695014, indiahttp://www.tug.org.in
