설명

The Canvas Scaler component is used for controlling the overall scale and pixel density of UI elements in the Canvas. This scaling affects everything under the Canvas, including font sizes and image borders.

For a Canvas set to 'Screen Space - Overlay' or 'Screen Space - Camera', the Canvas Scaler UI Scale Mode can be set to Constant Pixel Size, Scale With Screen Size, or Constant Physical Size.

Using the Constant Pixel Size mode, positions and sizes of UI elements are specified in pixels on the screen. This is also the default functionality of the Canvas when no Canvas Scaler is attached. However, With the Scale Factor setting in the Canvas Scaler, a constant scaling can be applied to all UI elements in the Canvas.

Using the Scale With Screen Size mode, positions and sizes can be specified according to the pixels of a specified reference resolution. If the current screen resolution is larger then the reference resolution, the Canvas will keep having only the resolution of the reference resolution, but will scale up in order to fit the screen. If the current screen resolution is smaller than the reference resolution, the Canvas will similarly be scaled down to fit. If the current screen resolution has a different aspect ratio than the reference resolution, scaling each axis individually to fit the screen would result in non-uniform scaling, which is generally undesirable. Instead of this, the ReferenceResolution component will make the Canvas resolution deviate from the reference resolution in order to respect the aspect ratio of the screen. It is possible to control how this deviation should behave using the screenMatchMode setting.

Using the Constant Physical Size mode, positions and sizes of UI elements are specified in physical units, such as millimeters, points, or picas. This mode relies on the device reporting its screen DPI correctly. You can specify a fallback DPI to use for devices that do not report a DPI.

For a Canvas set to 'World Space' the Canvas Scaler can be used to control the pixel density of UI elements in the Canvas.

변수

defaultSpriteDPIThe pixels per inch to use for sprites that have a 'Pixels Per Unit' setting that matches the 'Reference Pixels Per Unit' setting.
dynamicPixelsPerUnitThe amount of pixels per unit to use for dynamically created bitmaps in the UI, such as Text.
fallbackScreenDPIThe DPI to assume if the screen DPI is not known.
matchWidthOrHeightSetting to scale the Canvas to match the width or height of the reference resolution, or a combination.
physicalUnitThe physical unit to specify positions and sizes in.
referencePixelsPerUnitIf a sprite has this 'Pixels Per Unit' setting, then one pixel in the sprite will cover one unit in the UI.
referenceResolutionThe resolution the UI layout is designed for.
scaleFactorScales all UI elements in the Canvas by this factor.
screenMatchModeA mode used to scale the canvas area if the aspect ratio of the current resolution doesn't fit the reference resolution.
uiScaleModeDetermines how UI elements in the Canvas are scaled.
