IDML 多边形到 SVG

Question

我在 idml 文件中有这个 Polygon

<Polygon Self="ue7" ContentType="Unassigned" StoryTitle="$ID/" ParentInterfaceChangeCount="" TargetInterfaceChangeCount="" LastUpdatedInterfaceChangeCount="" OverriddenPageItemProps="" HorizontalLayoutConstraints="FlexibleDimension FixedDimension FlexibleDimension" VerticalLayoutConstraints="FlexibleDimension FixedDimension FlexibleDimension" GradientFillStart="0 0" GradientFillLength="0" GradientFillAngle="0" GradientStrokeStart="0 0" GradientStrokeLength="0" GradientStrokeAngle="0" ItemLayer="uc5" Locked="false" LocalDisplaySetting="Default" GradientFillHiliteLength="0" GradientFillHiliteAngle="0" GradientStrokeHiliteLength="0" GradientStrokeHiliteAngle="0" AppliedObjectStyle="ObjectStyle/$ID/[Normal Graphics Frame]" Visible="true" Name="$ID/" ItemTransform="1 0 0 1 41.5 -14.555409553836853">

            </Properties>

    </Polygon>

现在我想将这些点转换为 svg 路径 我使用了svg中的curveto点，但似乎不太好。这是我的结果

 <!DOCTYPE html>
<html>
<body>

<svg height="10000" width="10000">

 
  
  <g transform="translate(300 400)">
   <path d="M105 -258.94488188905
   C105 -258.94488188905,105 -258.94488188905, 105 -171
   
    
   C105 -168, 105 -257.05511811095, 105 -78.94488188905001
   
   C201 -72, 120 -72, 282 -72
   
   C338 -209, 338 -167, 338 -251
   
   C105 -258.94488188905, 105 -258.94488188905, 105 -258.94488188905
    
    
     
   
   " stroke="black" fill="transparent"/>
  </g>
  
</svg>

indesign 的原始路径如下所示：

有人知道从PathPointArray解析这些点的正确方法

Answer 1

看起来 InDesign 使用的模型更接近于您在应用程序中操纵路径的方式（即一系列带手柄的点），并且不同于 SVG 模型（即一系列路径段）。

但它们可以通过不同的对齐方式进行转换：

InDesign                                    SVG

LeftDirection="105 -258.94488188905"        -- ignored as before the first point
Anchor="105 -258.94488188905"               M 105 -258.94488188905
RightDirection="105 -171"                   C 105 -171

LeftDirection="105 -257.05511811095"        105 -257.05511811095
Anchor="105 -168"                           105 -168
RightDirection="105 -78.94488188905001"     C 105 -78.94488188905001

LeftDirection="120 -72"                     120 -72
Anchor="201 -72"                            201 -72
RightDirection="282 -72"                    C 282 -72

LeftDirection="338 -167"                    338 -167
Anchor="338 -209"                           338 -209
RightDirection="338 -251"                   C 338 -251

LeftDirection="105 -258.94488188905"        105 -258.94488188905
Anchor="105 -258.94488188905"               105 -258.94488188905
RightDirection="105 -258.94488188905"       -- ignored as beyond the last point

如您所见，LeftDirection 坐标出现在Anchor 坐标之前。一条曲线段从RightDirection 和LeftDirection 跨越到Anchor 坐标。
