static void	CopySubResourceToImage (const ezGALTextureCreationDescription &desc, const ezGALTextureSubresource &subResource, const ezGALSystemMemoryDescription &memory, ezImage &out_image, bool bRemoveSRGB)
	Copies the given texture subresource from memory into out_image according to the texture description.
static ezImageView	MakeImageViewFromSubResource (const ezGALTextureCreationDescription &desc, const ezGALTextureSubresource &subResource, const ezGALSystemMemoryDescription &memory, ezImage &ref_tempImage, bool bRemoveSRGB)
	Returns an image view of the texture subresource in memory. If the format allows for it, the memory will be aliased, removing the need to copy the data but the view becomes invalid once the memory does. If this is not possible, the function reverts to calling CopySubResourceToImage with ref_tempImage used as the data storage. You can check if ref_tempImage is valid to figure out which code path was taken.
static void	CopySubResourceToMemory (const ezGALTextureCreationDescription &desc, const ezGALTextureSubresource &subResource, const ezGALSystemMemoryDescription &sourceMemory, ezArrayPtr< ezUInt8 > targetData, ezUInt32 uiTargetRowPitch)
	Copies a texture subresource memory to a new location with a different row pitch.

Static Public Attributes
static bool	s_bForceFullQualityAlways = false
	If enabled, textures are always loaded to full quality immediately. Mostly necessary for image comparison unit tests.

Detailed Description

Utility functions for texture format conversion and manipulation.

Member Function Documentation

ConfigureSampler()

void ezTextureUtils::ConfigureSampler ( ezTextureFilterSetting::Enum  filter, ezGALSamplerStateCreationDescription &  out_sampler  )

static

Configures a sampler state based on a texture filter setting.

Sets up filtering mode, addressing, and anisotropy based on the filter enum.

GalFormatToImageFormat()

ezImageFormat::Enum ezTextureUtils::GalFormatToImageFormat ( ezGALResourceFormat::Enum  format, bool  bRemoveSRGB  )

static

Converts a GPU texture format to the corresponding image format.

If bRemoveSRGB is true, sRGB formats are converted to their linear equivalents.

ImageFormatToGalFormat()

ezGALResourceFormat::Enum ezTextureUtils::ImageFormatToGalFormat ( ezImageFormat::Enum  format, bool  bSRGB  )

static

Converts an image format to the corresponding GPU texture format.

The bSRGB parameter determines whether to use sRGB or linear variants.

Todo:

Not supported by some GPUs ?
