Provides a UI component that inherits ICanvasRaycastFilter and performs its own input detection process. This component controls input detection by comparing the alpha value of the texture with the specified threshold.- ImageAlphaHitTestRaycastFilter - The texture's alpha value is compared with the threshold value to control input judgment.- RawImageAlphaHitTestRaycastFilter - The texture's alpha value is compared with the threshold value to control input judgment.- TextAlphaHitTestRaycastFilter - The alpha value of the font texture is compared with a threshold value to control input judgment.- TextMeshAlphaHitTestRaycastFilter - The alpha value of the font texture is compared with a threshold value to control input judgment.- SpritePhysicsShapeRaycastFilter - Input judgment processing is performed based on the information created with Custom Physics Shape.- AlphaMaskHitTestRaycastFilter - An alpha mask image is generated and compared with the specified threshold to control input judgment.
