Syntax

struct FAtlasedTextureSlot : public TIntrusiveLinkedList< FAtlasedTextureSlot >

Remarks

Structure holding information about where a texture is located in the atlas. Inherits a linked-list interface.

When a slot is occupied by texture data, the remaining space in the slot (if big enough) is split off into two new (smaller) slots, building a tree of texture rectangles which, instead of being stored as a tree, are flattened into two linked-lists:

AtlastEmptySlots: A linked-list of empty slots ready for texture data - iterates in same order as a depth-first-search on a tree
AtlasUsedSlots: An unordered linked-list of slots containing texture data

Variables

Type	Name	Description
uint32	Height	The height of the character
uint8	Padding	Uniform Padding. can only be zero or one. See ESlateTextureAtlasPaddingStyle.
uint32	Width	The width of the character
uint32	X	The X position of the character in the texture
uint32	Y	The Y position of the character in the texture
