AstroZoomLevel

是 AstroGraphics 和 AstroStyling 的一个选项，指定渲染图像的分辨率水平.

更多信息

  • AstroZoomLevel 提供天文图比例尺的以 2 为底的对数规范. 天文图缩放级别增加 1 对应于角分辨率增加 2 倍. AstroZoomLevel 值为 1 对应于整个星空的数据.

范例

打开所有单元 关闭所有单元

基本范例  (1)

用默认缩放级别显示星系中心的区域：

Wolfram Language code: AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> "Equatorial", AstroBackground -> AstroStyling[{"GalacticSky", "ShowConstellations" -> False}], AstroRange -> Quantity[30, "AngularDegrees"]]
Wolfram Language code: Options[%, AstroZoomLevel]

减少缩放级别以缩小背景图像的分辨率：

Wolfram Language code: AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> "Equatorial", AstroBackground -> AstroStyling[{"GalacticSky", "ShowConstellations" -> False}], AstroRange -> Quantity[30, "AngularDegrees"], AstroZoomLevel -> 1]

范围  (2)

对同一片星空使用不同的缩放级别，增大背景图像的分辨率：

Wolfram Language code: Table[AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> "J2000", AstroBackground -> "GalacticSky", AstroRange -> Quantity[15, "AngularDegrees"], AstroZoomLevel -> zoom, ImageSize -> 250], {zoom, 1, 4}]

增大 M8 周围的缩放级别，自动计算范围并保持图像分辨率：

Wolfram Language code: Table[AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> {"J2000", Here, DateObject[{2023, 7, 1}]}, AstroBackground -> "GalacticSky", AstroZoomLevel -> zoom, ImageSize -> 250], {zoom, 3, 6}]
