AstroZoomLevel
AstroGraphicsおよびAstroStylingのオプションで,画像を描画する解像度レベルを指定する.
詳細
- AstroZoomLevelは地図スケールの2を底とする対数指定である.天文ズームレベルが1上がるごとに角分解能が2の倍数倍になる.値1のAstroZoomLevelは全天のデータに相当する.

AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> "Equatorial", AstroBackground -> AstroStyling[{"GalacticSky", "ShowConstellations" -> False}], AstroRange -> Quantity[30, "AngularDegrees"]]Options[%, AstroZoomLevel]AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> "Equatorial", AstroBackground -> AstroStyling[{"GalacticSky", "ShowConstellations" -> False}], AstroRange -> Quantity[30, "AngularDegrees"], AstroZoomLevel -> 1]スコープ (2)
空の同一部分に異なるズームレベルを使って背景画像の解像度を上げる:
Table[AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> "J2000", AstroBackground -> "GalacticSky", AstroRange -> Quantity[15, "AngularDegrees"], AstroZoomLevel -> zoom, ImageSize -> 250], {zoom, 1, 4}]M8周囲で範囲を自動計算し画像の解像度はそのままにしてズームレベルを上げる:
Table[AstroGraphics[Entity["Nebula", "M8"], AstroReferenceFrame -> {"J2000", Here, DateObject[{2023, 7, 1}]}, AstroBackground -> "GalacticSky", AstroZoomLevel -> zoom, ImageSize -> 250], {zoom, 3, 6}]関連するガイド
