Method	Description
GetRepackedSkin ( this o, string newName, Shader shader, Material &m, Texture2D &t, int maxAtlasSize = 1024, int padding = 2 ) : Skin	Creates and populates a duplicate skin with cloned attachments that are backed by a new packed texture atlas comprised of all the regions from the original skin. No Spine.Atlas object is created so there is no way to find AtlasRegions except through the Attachments using them.
ToAtlasRegion ( this s, AtlasPage page ) : AtlasRegion	Creates a Spine.AtlasRegion from a UnityEngine.Sprite.
ToAtlasRegion ( this s, Material material ) : AtlasRegion	Creates a Spine.AtlasRegion from a UnityEngine.Sprite. This creates a new AtlasPage object for every AtlasRegion you create. You can centralize Material control by creating a shared atlas page using Material.ToSpineAtlasPage and using the sprite.ToAtlasRegion(AtlasPage) overload.
ToAtlasRegionPMAClone ( this s, Shader shader ) : AtlasRegion	Creates a Spine.AtlasRegion that uses a premultiplied alpha duplicate of the Sprite's texture data.
ToSpineAtlasPage ( this m ) : AtlasPage	Creates a new Spine.AtlasPage from a UnityEngine.Material. If the material has a preassigned texture, the page width and height will be set.
ToSprite ( this ar, float pixelsPerUnit = 100 ) : Sprite

Private Methods

Method	Description
ApplyPMA ( this texture, bool applyImmediately = true ) : void
GetAtlasRegion ( this a ) : AtlasRegion	Tries to get the backing AtlasRegion of an attachment if it is renderable. Returns null for non-renderable attachments.
GetMainTexture ( this region ) : Texture2D	Convenience method for getting the main texture of the material of the page of the region.
GetSpineAtlasRect ( this region, bool includeRotate = true ) : Rect	Returns a Rect of the AtlasRegion according to Spine texture coordinates. (x-right, y-down)
GetUnityRect ( this region ) : Rect	Gets the Rect of an AtlasRegion according to Unity texture coordinates (x-right, y-up). This overload relies on region.page.height being correctly set.
GetUnityRect ( this region, int textureHeight ) : Rect	Gets the Rect of an AtlasRegion according to Unity texture coordinates (x-right, y-up).
InverseLerp ( float a, float b, float value ) : float
IsRenderable ( Attachment a ) : bool
SpineUnityFlipRect ( this rect, int textureHeight ) : Rect	Get a rect with flipped Y so that a Spine atlas rect gets converted to a Unity Sprite rect and vice versa.
TextureRectToUVRect ( Rect textureRect, int texWidth, int texHeight ) : Rect	Normalize a texture Rect into UV coordinates.
ToAtlasRegion ( this s, bool isolatedTexture = false ) : AtlasRegion
ToTexture ( this ar, bool applyImmediately = true ) : Texture2D
UVRectToAtlasRegion ( Rect uvRect, string name, AtlasPage page, float offsetX, float offsetY, bool rotate ) : AtlasRegion	Creates a new Spine AtlasRegion according to a Unity UV Rect (x-right, y-up, uv-normalized).
UVRectToTextureRect ( Rect uvRect, int texWidth, int texHeight ) : Rect	Denormalize a uvRect into a texture-space Rect.

Method Details

GetRepackedSkin() public static method

Creates and populates a duplicate skin with cloned attachments that are backed by a new packed texture atlas comprised of all the regions from the original skin.

No Spine.Atlas object is created so there is no way to find AtlasRegions except through the Attachments using them.

public static GetRepackedSkin ( this o, string newName, Shader shader, Material &m, Texture2D &t, int maxAtlasSize = 1024, int padding = 2 ) : Skin
o	this
newName	string
shader	UnityEngine.Shader
m	UnityEngine.Material
t	UnityEngine.Texture2D
maxAtlasSize	int
padding	int
return	Skin

ToAtlasRegion() public static method

Creates a Spine.AtlasRegion from a UnityEngine.Sprite.

public static ToAtlasRegion ( this s, AtlasPage page ) : AtlasRegion
s	this
page	AtlasPage
return	AtlasRegion

ToAtlasRegion() public static method

Creates a Spine.AtlasRegion from a UnityEngine.Sprite. This creates a new AtlasPage object for every AtlasRegion you create. You can centralize Material control by creating a shared atlas page using Material.ToSpineAtlasPage and using the sprite.ToAtlasRegion(AtlasPage) overload.

public static ToAtlasRegion ( this s, Material material ) : AtlasRegion
s	this
material	UnityEngine.Material
return	AtlasRegion

ToAtlasRegionPMAClone() public static method

Creates a Spine.AtlasRegion that uses a premultiplied alpha duplicate of the Sprite's texture data.

public static ToAtlasRegionPMAClone ( this s, Shader shader ) : AtlasRegion
s	this
shader	UnityEngine.Shader
return	AtlasRegion

ToSpineAtlasPage() public static method

Creates a new Spine.AtlasPage from a UnityEngine.Material. If the material has a preassigned texture, the page width and height will be set.

public static ToSpineAtlasPage ( this m ) : AtlasPage
m	this
return	AtlasPage

ToSprite() public static method

public static ToSprite ( this ar, float pixelsPerUnit = 100 ) : Sprite
ar	this
pixelsPerUnit	float
return	UnityEngine.Sprite
