Detailed Description

A class containing image meta data, such as format and dimensions.

This class has no associated behavior or functionality, and its getters and setters have no effect other than changing the contained value. It is intended as a container to be modified by image utils and loaders.

Member Function Documentation

◆ SetNumArrayIndices()

void xiiImageHeader::SetNumArrayIndices ( xiiUInt32 uiNumArrayIndices)
inline

Sets the number of array indices.

Setting this to 0 will result in an empty image.

◆ SetNumFaces()

void xiiImageHeader::SetNumFaces ( xiiUInt32 uiNumFaces)
inline

Sets the number of cubemap faces. Use 1 for a non-cubemap.

Setting this to 0 will result in an empty image.

◆ SetNumMipLevels()

void xiiImageHeader::SetNumMipLevels ( xiiUInt32 uiNumMipLevels)
inline

Sets the number of mip levels, including the full-size image.

Setting this to 0 will result in an empty image.
