Remarks

Base class texture atlases in Slate

Variables

	Name	Description
TArray< uint8 >	AtlasData	Actual texture data contained in the atlas
FAtlasedTexture...	AtlasEmptySlots	The list of atlas slots pointing to empty texture data in the atlas
uint32	AtlasHeight	Height of the atlas
ESlateTextureAt...	AtlasOwnerThread	The type of thread that owns this atlas - this is the only thread that can safely update it
FAtlasedTexture...	AtlasUsedSlots	The list of atlas slots pointing to used texture data in the atlas
uint32	AtlasWidth	Width of the atlas
bool	bNeedsUpdate	True if this texture needs to have its rendering resources updated
bool	bUpdatesAfterInitialization	True if this texture can update after initialziation and we should preserve the atlas slots and cpu memory
uint32	BytesPerPixel	Bytes per pixel in the atlas
ESlateTextureAt...	PaddingStyle	Padding style

Constructors

	Name	Description
	FSlateTextureAtlas ( uint32 InWidth, uint32 InHeight, uint32 InBytesPerPixel, ESlateTextureAtlasPaddingStyle InPa..., bool bInUpdatesAfterInitialization )

Destructors

	Name	Description
	~FSlateTextureAtlas()

Functions

	Name	Description
const FAtlas...	AddTexture ( uint32 TextureWidth, uint32 TextureHeight, const TArray< uint8 >& Data )	Adds a texture to the atlas
void	ConditionalUpdateTexture()	Updates the texture used for rendering if needed
void	CopyDataIntoSlot ( const FAtlasedTextureSlot* Slo..., const TArray< uint8 >& Data )	Copies texture data into the atlas at a given slot
void	CopyRow ( const FCopyRowData& CopyRowData )	Copies a single row from a source texture to a dest texture, respecting the padding.
void	EmptyAtlasData()	Clears atlas cpu data. It does not clear rendering data
const FAtlas...	FindSlotForTexture ( uint32 InWidth, uint32 InHeight )	Finds the optimal slot for a texture in the atlas
uint32	GetHeight()
const FAtlas...	GetSlotAtPosition ( FIntPoint InPosition )
uint32	GetWidth()
void	InitAtlasData()	Creates enough space for a single texture the width and height of the atlas
void	MarkTextureDirty()	Marks the texture as dirty and needing its rendering resources updated
void	ZeroRow ( const FCopyRowData& CopyRowData )	Zeros out a row in the dest texture (used with PaddingStyle == PadWithZero).

Classes
