Asymptote 学习记录(5) 模块roundedpath的用法
看这个代码:
1 import settings; 2 settings.tex = "pdflatex"; 3 pdfviewer="/usr/bin/okular"; 4 outformat="pdf"; 5 texpreamble("\usepackage{CJKutf8}\AtBeginDocument{\begin{CJK}{UTF8}{gbsn}}\AtEndDocument{\clearpage\end{CJK}}"); 6 // example file for 'roundedpath.asy' 7 // written by stefan knorr 8 // import needed packages 9 import roundedpath; 10 // define open and closed path 11 path A = (0,0)--(10,10)--(30,10)--(20,0)--(30,-10)--(10,-10); 12 path B = A--cycle; 13 draw(shift(-60,0)*A, green); 14 draw(shift(-30,0)*roundedpath(A,1), red); 15 // draw open path and some modifications 16 17 for (int i = 1; i < 20; ++i) 18 draw(roundedpath(A,i/4), rgb(1 - i*0.049, 0, i*0.049) + linewidth(0.5)); 19 20 draw(shift(-60,-30)*B, green); 21 draw(shift(-30,-30)*roundedpath(B,1), red); 22 23 //draw closed path and some modifications 24 25 for (int i = 1; i < 20; ++i) // only round edges 26 draw(shift(0,-30)*roundedpath(B,i/4), rgb(0.5, i*0.049,0) + linewidth(0.5)); 27 28 for (int i = 1; i < 20; ++i) // round edged and scale 29 draw(shift(0,-60)*roundedpath(B,i/4,1-i/50), rgb(1, 1 - i*0.049,i*0.049) + linewidth(0.5)); 30 31 for (int i = 1; i < 50; ++i) // shift (round edged und scaled shifted version) 32 draw(shift(-30,-60)*shift(10,0)*roundedpath(shift(-10,0)*B,i/10,1-i/80), rgb( i*0.024, 1 - i*0.024,0) + linewidth(0.5)); 33 34 for (int i = 1; i < 20; ++i) // shift (round edged und scaled shifted version) 35 draw(shift(-60,-60)*shift(10,0)*roundedpath(shift(-10,0)*B,i/4,1-i/50), gray(i/40));
