包路径：org.geoserver.wms.GetLegendGraphicRequest
类名称：GetLegendGraphicRequest
方法名：getLegendOptions

GetLegendGraphicRequest.getLegendOptions介绍

[英]Returns the possibly empty set of key/value pair parameters to control some aspects of legend generation.

These parameters are meant to be passed as the request parameter "LEGEND_OPTIONS" with the format LEGEND_OPTIONS=multiKey:val1,val2,val3;singleKey:val.

The known options, all optional, are:

  • fontName: name of the system font used for legend rule names. Defaults to "Sans-Serif"
  • fontStyle: one of "plain", "italic" or "bold"
  • fontSize: integer for the font size in pixels
  • fontColor: a String that represents an opaque color as a 24-bit integer
  • bgColor: allows to override the legend background color
  • fontAntiAliasing: a boolean indicating whether to use antia aliasing in font rendering. Anything of the following works: "yes", "true", "1". Anything else means false.
  • forceLabels: "on" means labels will always be drawn, even if only one rule is available. "off" means labels will never be drawn, even if multiple rules are available.
  • forceTitles: "off" means titles will never be drawn, even if multiple layers are available.
  • minSymbolSize: a number defining the minimum size to be rendered for a symbol (defaults to 3).
    [中]返回一组可能为空的键/值对参数，以控制图例生成的某些方面。
    这些参数将作为请求参数"LEGEND_OPTIONS"传递，格式为LEGEND_OPTIONS=multiKey:val1,val2,val3;singleKey:val。
    已知选项（均为可选）包括：
    *fontName：用于图例规则名称的系统字体的名称。默认为“无衬线”
    *fontStyle：“普通”、“斜体”或“粗体”之一
    *fontSize：字体大小的整数，以像素为单位
    *fontColor：将不透明颜色表示为24位整数的String
    *bgColor：允许覆盖图例背景色
    *fontAntiAliasing：一个布尔值，指示是否在字体呈现中使用抗锯齿。以下任何作品：“是”、“正确”、“1”。其他任何东西都是假的。
    *forceLabels：“on”表示将始终绘制标签，即使只有一条规则可用。“关闭”表示即使有多条规则可用，也不会绘制标签。
    *forceTitles：“关闭”表示即使有多个图层可用，也不会绘制标题。
    *minSymbolSize：定义符号要呈现的最小大小的数字（默认为3）。
