Calculate() [1/2]

TextureExtent rex::xenos::TextureExtent::Calculate ( const FormatInfo * format_info, u32 pitch, u32 height, u32 depth, bool is_tiled, bool is_guest )

static

Returns the extent of a texture level from its block layout and size.

Parameters

is_tiled	True for a tiled texture, false for a linear one.
is_guest	True to pad as guest memory does, false for a packed host layout.

Calculate() [2/2]

TextureExtent rex::xenos::TextureExtent::Calculate ( const TextureInfo * texture_info, bool is_guest )

static

Returns the extent of the base level of a texture.

Parameters

texture_info	The texture, using its base level size.
is_guest	True for the padded guest memory layout, false for a packed host layout.

GetAllBlocks()

u32 rex::xenos::TextureExtent::GetAllBlocks ( ) const

inline

Returns the block count including padding in every dimension.

GetVisibleBlocks()

u32 rex::xenos::TextureExtent::GetVisibleBlocks ( ) const

inline

Returns the block count including row padding but only the visible block rows.
