我想让我的模型具有很多颜色。我的意思是我希望我的DoLine
使每个时间线具有相似但不相同的颜色。所以,我没有通过递归在postscript中改变线条的颜色
/red 0.41 def
/green 0.1 def
/blue 0.21 def
/incRed {/red red 0.01 add} def
/incGreen {/green green 0.03 add} def
/incBlue {/blue blue 0.05 add} def
和我DoLine
/DoLine
{
incRed
incGreen
incBlue
red green blue setrgbcolor
rotation rotate
0 linelen rlineto
currentpoint stroke
translate 0 0 moveto
} def
但它的输出我只有一种颜色的百通被设置为
/red 0.41 def
/green 0.1 def
/blue 0.21 def
有什么我错过了什么?这是我所有的代码,如果u需要它
