Custom Graphics••Simple customizationHigher level customization(Do you see why our earlier construction with \pscustom worked? There wehad three paths, with the beginning of each path the same as the current point).So, what’s the way out? PSTricks also has a command \psarcn (“n”for negative) which draws the arc of a circle in the clockwise direction.Thus \psarc(0,0){1.5}{210}{330} and \psarcn(0,0){1.5}{330}{210}produce the same curve, but drawn in opposite directions:Online L A TEX TutorialPart II – GraphicsPSTricks\psarc(0,0){1.5}{210}{330}\psarcn(0,0){1.5}{330}{210}Now we can easily draw the crescent:\begin{pspicture}(-1.5,-2)(1.5,0.5)\pscustom[fillstyle=solid,%fillcolor=Lavender,%linecolor=Red]{%\psarc(0,0){1.5}{150}{30}\psarcn(0,1.5){1.5}{330}{210}}\end{pspicture}Here’s another example, using \psarcnE Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.

Custom Graphics\psset{unit=1.5cm}\begin{pspicture}(0,-1)(3,1)\psset{linestyle=none,fillstyle=solid}\pscustom[fillcolor=Yellow]{%\psarc(1,0){1}{60}{-60}\psarcn(2,0){1}{240}{120}}\pscustom[fillcolor=Blue]{%\psarc(2,0){1}{240}{120}\psarcn(1,0){1}{60}{-60}}\pscustom[fillcolor=Green]{%\psarc(1,0){1}{-60}{60}\psarc(2,0){1}{120}{240}}\end{pspicture}The (default) behavior of PSTricks in joining the current point to the beginningof the new path can sometimes be of advantage. For example, in ourconstruction of a “stem” earlier, we need not explicitly mention the “base”,using\psline, if the two curves are specified to be drawn in suitable directions:\begin{pspicture}(-1,-1)(1,0)\pscustom[linestyle=none,%fillstyle=solid,%fillcolor=Red]{%\psplot{0}{-1}{x 1 add 2 exp 1 sub}\psplot{1}{0}{x 1 sub 2 exp 1 sub}}\end{pspicture}8.2.2. Current point againAnother feature to note is that the paths drawn by \psline and \pscurvemake use of the current point as the first point; so also does \psplot withSimple customizationHigher level customizationOnline L A TEX TutorialPart II – GraphicsPSTricksE Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.
