Detailed Description

Texture Palette class. Stores a list of textures, each with its own texture handle. This the textures to be stored separately from the objects, which allows multiple objects to share the same textures.

Sets the desired load size for the image. If the loaded image is larger than the specified dimensions, it will be scaled down during the load.

Parameters

i	The index of the texture
width	The desired width
height	The desired height

bool DisableImageSharing ( int index )

Disables image sharing for the Image at the given index and ensures that the index refers to a unique Image instance. Note: If you want to disable image sharing for an Image that is not yet in a palette, you should call AllowImageSharing(false) on the Image.

Parameters

index The index of the texture to disable image sharing. The Image must already be loaded in the palette.

Returns: true on success; false on failure (Invalid index or Image could not be guarenteed unique)

static bool DownsizeImage	(	Image *	image,
		int	desiredWidth,
		int	desiredHeight

static

Scales down an image to the next power-of-two size where (width <= desiredWidth || height <= desiredHeight) Maintains aspect ratio. Note: This method may be removed from the TexturePalette in the future.

TexturePaletteEntry* Entry ( int i )

Returns the texture palette entry at index i

int FindAvailableSlot ( void )

Finds an unused slot in the texture palette.

Returns: The index of the first unused slot in the palette.

int FindTextureByName ( const char * name )

Finds a texture based on its filename

Parameters

name	The filename of the texture to find

Returns: The index if found, -1 if not found

bool GenerateInline ( int i )

Returns: True if the image is to be generated as inline code

Parameters

i	The index of the texture

void GenerateInline	(	int	i,
		bool	val
	)

Set True if the image is to be generated as inline code

Parameters

i	The index of the texture
val

Returns the height of the texture image in pixels

Parameters

i	The index of the texture to get the height of

Returns: The height of the texture image in pixels

void InvalidateTexture ( int i )

Invalidate the texture at the given index, causing it to be rebound the next time it is referencd

Parameters

i	The index of the texture

void InvalidateTextures ( void )

Invalidates all of the textures in the palette, forcing them to be rebound the next time they are referenced by an object.

void PaletteSize ( int newSize )

Resize texture palette with the indicated number of entries

Parameters

Compress using the current compression settings for the texture and scale down to the DesiredLoadSize.
