调整文本行距brightscript

Question

Bellow是使用roImageCanvas在Roku中显示字符串的代码。

 canvas = CreateObject("roImageCanvas")    
 port = CreateObject("roMessagePort")
 canvas.SetMessagePort(port)
 items = []

 items.Push({
  Text: "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s"
  TextAttrs:{ font: "small", color: "#a0a0a0" ,Direction:"LeftToRight",HAlign:"Left",VAlign:"top"}
  TargetRect: {x: 550, y: 75, w: 300, h: 500}
 })

 canvas.SetLayer(0, { Color: "#ff000000", CompositionMode: "Source" })
 canvas.SetLayer(1, items)
 canvas.Show()

这将创建一个类似于下面的输出

​

可以调整每一行之间的间距吗？

注意:我需要使用roImageCanvas，，因为这个页面需要一些带有图像的图形

Answer 1

不幸的是，在roImageCanvas上控制间距的唯一方法是使用自己的TargetRects将文本拆分成单独的字符串。
