8.1.2. New stylesWe can also freeze certain parameter values under a new name using thecommand \newpsstyle and then use it with various graphics objects, as inthe example below:\newpsstyle{newdots}%{linestyle=dotted,%dotsep=1pt,%linecolor=Green}\psset{unit=0.5cm}\begin{pspicture}(0,-0.5)(8.33,4.5)\pspolygon[linecolor=Blue](0,0)(8.33,0)(3,4)\psline[style=newdots](0,0)(3.33,1.67)(8.33,0)\psline[style=newdots](3.33,1.67)(3.33,0)\pscircle[style=newdots,linecolor=Red](3.33,1.67){1.67}\end{pspicture}Custom GraphicsSimple customizationHigher level customizationOnline L A TEX TutorialPart II – GraphicsPSTricksThe syntax of the general command is\newpsstyle{name}%{parameter1=value1}%parameter1=value1. . . . . . . . . . . . }Note that any parameter value set in \newpsstyle can be changed the usualway, as seen in the \pscircle of the above example.E Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.

8.2. Higher level customizationApart from creating variant objects by merely tweaking the parameter settingsof predefined objects, PSTricks also allows us to create our own graphicsobjects by combining predefined objects in various ways, using the command\pscustom. Let’s look at an example to see this command in action. Suppose(for whatever reason), we want to draw a red club suit shown below:•• •Drawing the top part is easy, using our \bigdots, of the first section.Custom GraphicsSimple customizationHigher level customizationOnline L A TEX TutorialPart II – GraphicsPSTricks\psset{unit=1.5cm}\begin{pspicture}(-1,-1)(2,1.5)\bigdots(0,0)(0.8,0)(0.4,0.75)\end{pspicture}•• •Next we draw the stem. The shape of the stem—it can be scaled to the neededsize later—can be drawn using two parabolic arcs and a line segment as shownbelow:We’ve included the arrows to show the direction of drawing. The code forproducing this (without the arrows) is shown below:E Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.
