Public Member Functions inherited from CTexture
	CTexture (unsigned int width=0, unsigned int height=0, XB_FMT format=XB_FMT_A8R8G8B8)

virtual	~CTexture ()

bool	LoadFromMemory (unsigned int width, unsigned int height, unsigned int pitch, XB_FMT format, bool hasAlpha, const unsigned char *pixels)

bool	UploadFromMemory (unsigned int width, unsigned int height, unsigned int pitch, unsigned char *pixels, KD_TEX_FMT format=KD_TEX_FMT_SDR_RGBA8, KD_TEX_ALPHA alpha=KD_TEX_ALPHA_OPAQUE, KD_TEX_SWIZ swizzle=KD_TEX_SWIZ_RGBA)
	Attempts to upload a texture directly from a provided buffer Unlike LoadFromMemory() which copies the texture into an intermediate buffer, the texture gets uploaded directly to the GPU if circumstances allow.

bool	LoadPaletted (unsigned int width, unsigned int height, unsigned int pitch, XB_FMT format, const unsigned char pixels, const COLOR palette)

void	Update (unsigned int width, unsigned int height, unsigned int pitch, XB_FMT format, const unsigned char *pixels, bool loadToGPU)

void	LoadToGPUAsync ()
	Uploads the texture to the GPU.

virtual void	SyncGPU ()
	Blocks execution until the previous GFX commands have been processed.

virtual bool	SupportsFormat (KD_TEX_FMT textureFormat, KD_TEX_SWIZ textureSwizzle)
	Checks if the processing pipeline can handle the texture format/swizzle.

bool	HasAlpha () const

void	SetAlpha (bool hasAlpha)

void	SetMipmapping ()

bool	IsMipmapped () const
	return true if we want to mipmap

void	SetScalingMethod (TEXTURE_SCALING scalingMethod)
	sets the scaling method. scanout systems might support more than NN/linear.

TEXTURE_SCALING	GetScalingMethod () const
	returns the scaling method.

int32_t	GetOrientation () const

void	SetOrientation (int orientation)

void	SetCacheMemory (bool bCacheMemory)
	retains a shadow copy of the texture on the CPU side.

bool	GetCacheMemory () const
	returns true if a shadow copy is kept on the CPU side.

uint8_t *	GetPixels () const
	returns a pointer to the staging texture.

uint32_t	GetPitch () const
	return the size of one row in bytes.

uint32_t	GetRows () const
	return the number of rows (number of blocks in the Y direction).

uint32_t	GetTextureWidth () const
	return the total width of the texture, which might be scaled to fit its displayed size.

uint32_t	GetTextureHeight () const
	return the total height of the texture, which might be scaled to fit its displayed size.

uint32_t	GetWidth () const
	return the total width of "active" area, which might be equal or lower than the texture width due to alignment.

uint32_t	GetHeight () const
	return the total height of "active" area, which might be equal or lower than the texture height due to alignment.

uint32_t	GetOriginalWidth () const
	return the original width of the image, before scaling/cropping

uint32_t	GetOriginalHeight () const
	return the original height of the image, before scaling/cropping

	Load a texture from a file Loads a texture from a file, restricting in size if needed based on maxHeight and maxWidth. Note that these are the ideal size to load at - the returned texture may be smaller or larger than these.

static std::unique_ptr< CTexture >	LoadFromFileInMemory (unsigned char *buffer, size_t bufferSize, const std::string &mimeType, unsigned int idealWidth=0, unsigned int idealHeight=0, CAspectRatio::AspectRatio aspectRatio=CAspectRatio::CENTER)
	Load a texture from a file in memory Loads a texture from a file in memory, restricting in size if needed based on maxHeight and maxWidth. Note that these are the ideal size to load at - the returned texture may be smaller or larger than these.

bool	ConvertToLegacy (uint32_t width, uint32_t height, uint8_t *src)
	Textures might be in a single/dual channel format with L/A/I/LA swizzle. DX and GLES 2.0 don't handle some/all at the moment. This function can convert the texture into a traditional BGRA format.
