Functions

Public

Name Remarks Include Path Unreal Specifiers

bool BuildTexture ( TArray< struct FImage >& SourceMips,
TArray< struct FImage >& AssociatedNormalSourceMips,
const FTextureBuildSettings& BuildSettings,
FStringView DebugTexturePathName,
TArray< FCompressedImage2D >& OutTextureMips,
uint32& OutNumMipsInTail,
uint32& OutExtData,
UE::TextureBuildUtilities::FTextureBuildMetadata* OutMetadata
)

 Builds a texture from source images. TextureCompressorModule.h  

Static

Name Remarks Include Path Unreal Specifiers

static void AdjustImageColors ( FImage& Image,
const FTextureBuildSettings& InBuildSettings
)

 Adjusts the colors of the image using the specified settings TextureCompressorModule.h  

static bool DetermineAlphaChannelTransparency ( const FTextureBuildSettings& InBuildSettings,
const FLinearColor& InChannelMin,
const FLinearColor& InChannelMax,
bool& bOutAlphaIsTransparent
)

 Given the channel min/max for the top mip of a texture's source, determine whether there will be any transparency after image processing occurs, and thus the texture will need to be BC3 for the purposes of AutoDXT format selection. TextureCompressorModule.h  

static void GenerateAngularFilteredMips ( TArray< FImage >& InOutMipChain,
int32 NumMips,
uint32 DiffuseConvolveMipLevel
)

 Generates angularly filtered mips. TextureCompressorModule.h  

static void GenerateBaseCubeMipFromLongitudeLatitude2D ( FImage* OutMip,
const FImage& SrcImage,
const FTextureBuildSettings& InBuildSettings
)

 Generates the base cubemap mip from a longitude-latitude 2D image. TextureCompressorModule.h  

static void GenerateBaseCubeMipFromLongitudeLatitude2D ( FImage* OutMip,
const FImage& SrcImage,
const uint32 MaxCubemapTextureResolution,
uint8 SourceEncodingOverride
)

 Generates the base cubemap mip from a longitude-latitude 2D image. TextureCompressorModule.h  

static void GenerateMipChain ( const FTextureBuildSettings& Settings,
const FImage& BaseImage,
TArray< FImage >& OutMipChain,
uint32 MipChainDepth
)

 Generate a full mip chain. The input mip chain must have one or more mips. TextureCompressorModule.h  

static int32 GetMipCountForBuildSettings ( int32 InMip0SizeX,
int32 InMip0SizeY,
int32 InMip0NumSlices,
int32 InExistingMipCount,
const FTextureBuildSettings& InBuildSettings,
int32& OutMip0SizeX,
int32& OutMip0SizeY,
int32& OutMip0NumSlices
)

 Returns the number of mips that the given texture will generate with the given build settings, as well as the size of the top mip. TextureCompressorModule.h
