Description

Class that represents textures in C# code.

Use this class to create textures, or to modify existing texture assets.

The ImageConversion class provides extension methods to this class that handle image encoding functionality. For details on those methods, see the ImageConversion documentation.

Do not assume that the texture will be created and available in Awake. All texture uploads are synchronized on the Main thread at Start. Perform texture operations in Start.

Static Properties

blackTextureGets a small Texture with all black pixels.
grayTextureGets a small Texture with all gray pixels.
linearGrayTextureGets a small Texture with all gray pixels.
normalTextureGets a small Texture with pixels that represent surface normal vectors at a neutral position.
redTextureGets a small Texture with all red pixels.
whiteTextureGets a small Texture with all white pixels.

Properties

activeMipmapLimitThe number of high resolution mipmap levels from the texture that Unity doesn't upload to the GPU. (Read Only)
alphaIsTransparencyIndicates whether this texture was imported with TextureImporter.alphaIsTransparency enabled. This setting is available only in the Editor scripts. Note that changing this setting will have no effect; it must be enabled in TextureImporter instead.
calculatedMipmapLevelThe mipmap level calculated by the streaming system, which takes into account the streaming Cameras and the location of the objects containing this Texture. This is unaffected by requestedMipmapLevel or minimumMipmapLevel.
desiredMipmapLevelThe mipmap level that the streaming system would load before memory budgets are applied.
formatThe format of the pixel data in the texture (Read Only).
ignoreMipmapLimitThis property causes a texture to ignore all texture mipmap limit settings.
loadedMipmapLevelThe mipmap level that is currently loaded by the streaming system.
loadingMipmapLevelThe mipmap level that the mipmap streaming system is in the process of loading.
minimumMipmapLevelRestricts the mipmap streaming system to a minimum mip level for this Texture.
mipmapLimitGroupThe name of the texture mipmap limit group that this texture is associated with. (Read Only)
requestedMipmapLevelThe mipmap level to load.
streamingMipmapsDetermines whether mipmap streaming is enabled for this Texture.
streamingMipmapsPrioritySets the relative priority for this Texture when reducing memory size to fit within the memory budget.
vtOnlyReturns true if the VTOnly checkbox was checked when the texture was imported; otherwise returns false. For additional information, see TextureImporter.vtOnly.

Constructors

Texture2DCreate a new empty texture.

Public Methods

ApplyCopies changes you've made in a CPU texture to the GPU.
ClearMinimumMipmapLevelResets the minimumMipmapLevel field.
ClearRequestedMipmapLevelResets the requestedMipmapLevel field.
CompressCompress texture at runtime to DXT/BCn or ETC formats.
GetPixelGets the pixel color at coordinates (x, y).
GetPixelBilinearGets the filtered pixel color at the normalized coordinates (u, v).
GetPixelDataGets the raw data from a texture.
GetPixelsGets the pixel color data for a mipmap level as Color structs.
GetPixels32Gets the pixel color data for a mipmap level as Color32 structs.
GetRawTextureDataGets the raw data from a texture, as an array that points to memory.
IsRequestedMipmapLevelLoadedChecks to see whether the mipmap level set by requestedMipmapLevel has finished loading.
LoadRawTextureDataSets the raw data of an entire texture in CPU memory.
PackTexturesPacks multiple Textures into a texture atlas.
ReadPixelsReads pixels from the current render target and writes them to a texture.
ReinitializeReinitializes a Texture2D, making it possible for you to replace width, height, textureformat, and graphicsformat data for that texture.
SetPixelSets the pixel color at coordinates (x,y).
SetPixelDataSets the raw data of an entire mipmap level directly in CPU memory.
SetPixelsSets the pixel colors of an entire mipmap level.
SetPixels32Sets the pixel colors of an entire mipmap level.
UpdateExternalTextureUpdates Unity texture to use different native texture object.

Static Methods

CreateExternalTextureCreates a Unity Texture out of an externally created native texture object.
GenerateAtlasPacks a set of rectangles into a square atlas, with optional padding between rectangles.

Inherited Members

Static Properties

allowThreadedTextureCreationAllow Unity internals to perform Texture creation on any thread (rather than the dedicated render thread).
currentTextureMemoryThe amount of memory that all Textures in the scene use.
desiredTextureMemoryThe total size of the Textures, in bytes, that Unity loads if there were no other constraints. Before Unity loads any Textures, it applies the memory budget which reduces the loaded Texture resolution if the Texture sizes exceed its value. The desiredTextureMemory value takes into account the mipmap levels that Unity has requested or that you have set manually.For example, if Unity does not load a Texture at full resolution because it is far away or its requested mipmap level is greater than 0, Unity reduces the desiredTextureMemory value to match the total memory needed.The desiredTextureMemory value can be greater than the Texture.targetTextureMemory value.
GenerateAllMipsCan be used with Texture constructors that take a mip count to indicate that all mips should be generated. The value of this field is -1.
nonStreamingTextureCountThe number of non-streaming Textures in the scene. This includes instances of Texture2D and CubeMap Textures. This does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally.
nonStreamingTextureMemoryThe amount of memory Unity allocates for non-streaming Textures in the scene. This only includes instances of Texture2D and CubeMap Textures. This does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally.
streamingMipmapUploadCountHow many times has a Texture been uploaded due to Texture mipmap streaming.
streamingRendererCountNumber of renderers registered with the Texture streaming system.
streamingTextureCountNumber of streaming Textures.
streamingTextureDiscardUnusedMipsThis property forces the streaming Texture system to discard all unused mipmaps instead of caching them until the Texture memory budget is exceeded. This is useful when you profile or write tests to keep a predictable set of Textures in memory.
streamingTextureForceLoadAllForce streaming Textures to load all mipmap levels.
streamingTextureLoadingCountNumber of streaming Textures with mipmaps currently loading.
streamingTexturePendingLoadCountNumber of streaming Textures with outstanding mipmaps to be loaded.
targetTextureMemoryThe total amount of Texture memory that Unity allocates to the Textures in the scene after it applies the memory budget and finishes loading Textures. `targetTextureMemory`also takes mipmap streaming settings into account. This value only includes instances of Texture2D and CubeMap Textures. This value does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally.
totalTextureMemoryThe total amount of Texture memory that Unity would use if it loads all Textures at mipmap level 0. This is a theoretical value that does not take into account any input from the streaming system or any other input, for example when you set the`Texture2D.requestedMipmapLevel` manually. To see a Texture memory value that takes inputs into account, use `desiredTextureMemory`. `totalTextureMemory` only includes instances of Texture2D and CubeMap Textures. This value does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally.
