檢視 $triregionnumber 的原始碼

The number of regions that is in the triangular shape.

<big><big>'''Example'''</big></big> 

 $triregionnumber
 2

This means that there are two triangular regions. This command must be set after the command
[[$ranges]]. The "triregionnumber" must be smaller than the "range number". <br>

This command needs to be set before the command 
before the commands [[$triregiontype]], [[$triranges]], 

For example: <br>
 
 $triregionnumber
 2

 $triregiontype
 @type @periodnumber @period_spacing
 @type @periodnumber @period_spacing

 $triranges
 @f1 @f2 @f3 @f4 @f5 @f6
 @f1 @f2 @f3 @f4 @f5 @f6

@f1 @f2 @f3 @f4 @f5 @f6 are defined below according to its type
For the @type, it is the same definition as type in [[$emptyperiodshape]], see below
For  @periodnumber, it is repeating how many times
For the @period_spacing, it is defining the spacing of each repeating objects. 



'''<big><big>Example of @type </big></big>'''

@type.1~4 are triangle, circle, ellipse and rectangle. <br>

@type = 1 is triangle. If it have n-trianges, it it repeating along x direction. <br>
@type = 11 is triangle. If it have n-trianges, it it repeating along y direction. <br>
@type = 2 is circle. If it have n-circles, it it repeating along x direction. <br>
@type = 21 is circle. If it have n-circles, it it repeating along y direction. <br>
@type = 3 is ellipse. If it have n-ellipses, it it repeating along x direction. <br>
@type = 31 is ellipse. If it have n-ellipses, it it repeating along y direction. <br>
@type = 4 is rectangle. If it have n-rectangle, it it repeating along x direction. <br>
@type = 41 is rectangle. If it have n-rectangle, it it repeating along y direction. <br>

If the parameters are not show in the figure, you should set those parameters as 0.

Type5~8 are sine shape period structure. <br />

Type.5 and 6 can be determined by this expression:

<math>f_6<y<f_1sinf_2x+f_3;</math><br />

<math>f_4<x<f_5</math>

Type.7 and 8 can be determined by this expression:

<math>f_6<x<f_1sinf_2y+f_3;</math><br />

<math>f_4<y<f_5</math>
