描述

在 C# 代码中表示纹理的类。

使用该类可以创建纹理或修改现有的纹理资源

ImageConversion 类可为此类提供用于处理图像编码功能的扩展方法。有关这些方法的详细信息,请参阅 ImageConversion 文档。

静态变量

blackTexture获取一个全部为黑色像素的小纹理。
grayTexture获取一个全部为灰色像素的小纹理。
linearGrayTexture获取一个全部为灰色像素的小纹理。
normalTexture获取一个小纹理,其像素表示位于中立位置的表面法线矢量。
redTexture获取一个全部为红色像素的小纹理。
whiteTexture获取一个全部为白色像素的小纹理。

变量

alphaIsTransparency指示是否在启用 TextureImporter.alphaIsTransparency 的情况下导入此纹理。此设置仅在编辑器脚本中可用。请注意,更改此设置将不起作用;必须在 TextureImporter 中启用它。
calculatedMipmapLevel串流系统计算的 Mipmap 级别,其中考虑了串流摄像机以及包含此纹理的对象的位置。它不受 requestedMipmapLevel 或 minimumMipmapLevel 影响。
desiredMipmapLevel应用内存预算之前由串流系统加载的 Mipmap 级别。
format纹理中像素数据的格式(只读)。
loadedMipmapLevel串流系统当前加载的 Mipmap 级别。
loadingMipmapLevelMipmap 串流系统正在加载的 Mipmap 级别。
minimumMipmapLevel将 Mipmap 串流系统限制为此纹理的最低 Mip 级别。
requestedMipmapLevel要加载的 Mipmap 级别。
streamingMipmaps确定是否已为纹理启用 Mipmap 串流。
streamingMipmapsPriority在减小内存大小以满足内存预算时设置纹理的相对优先级。
vtOnlyReturns true if the VTOnly checkbox was checked when the texture was imported; otherwise returns false. For additional information, see TextureImporter.vtOnly.

构造函数

Texture2D创建一个新的空纹理。

公共函数

Apply实际应用任何先前的 SetPixel 和 SetPixels 更改。
ClearMinimumMipmapLevel重置 minimumMipmapLevel 字段。
ClearRequestedMipmapLevel重置 requestedMipmapLevel 字段。
CompressCompress texture at runtime to DXT/BCn or ETC formats.
GetPixel返回坐标 (x, y) 上的像素颜色。
GetPixelBilinear返回标准化坐标 (u, v) 处已过滤的像素颜色。
GetPixelDataGets raw data from a Texture for reading or writing.
GetPixelsRetrieves a copy of the the pixel color data for a given mip level. The colors are represented by Color structs.
GetPixels32Retrieves a copy of the pixel color data at a given mip level. The colors are represented by lower-precision Color32 structs.
GetRawTextureData从纹理中获取原始数据以进行读取或写入。
IsRequestedMipmapLevelLoaded检查通过 requestedMipmapLevel 设置的 Mipmap 级别是否已完成加载。
LoadRawTextureData使用原始预格式化数据填充纹理像素。
PackTextures将多个纹理打包到一个纹理图集中。
ReadPixelsReads the pixels from the current render target (the screen, or a RenderTexture), and writes them to the texture.
ReinitializeReinitializes the Texture to width by height, format to format and optionally creates mip maps. After reinitializing, Texture pixels will be undefined. This function is very similar to the Texture constructor, except it works on existing Texture object.调用 Apply 可实际将更改的像素上传到显卡。Texture.isReadable must be true.
SetPixel设置坐标 (x,y) 处的像素颜色。
SetPixelData用原始预格式化数据设置像素值。
SetPixels设置像素颜色块。
SetPixels32设置像素颜色块。
UpdateExternalTexture更新 Unity 纹理以使用不同的原生纹理对象。

静态函数

CreateExternalTextureCreates a Unity Texture out of an externally created native texture object.
GenerateAtlas将一组矩形打包成一个方形图集,并且可以选择在矩形之间进行填充。

继承的成员

静态变量

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 `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. It 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. It does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally.
