Method Details

importTextureSet

public static TextureSet importTextureSet(Wad wf)
                                   throws WadException,
IOException

Imports a TextureSet from a WAD File. This searches for the TEXTURE1/2 lumps and the PNAMES entry, and builds a new TextureSet from them. If the WAD does NOT contain a TEXTUREx entry, the returned set will be empty. If TEXTURE1/2 is present, but NOT PNAMES, a TextureException will be thrown.

Parameters:

wf - the WAD file to read from containing the required entries.

Returns:

a new texture set equivalent to the parsed data.

Throws:

TextureException - if a texture lump was found, but not PNAMES.

WadException - if the WAD itself cannot be read.

IOException - if an entry in a WAD file cannot be read.

isStrifeTextureData

public static boolean isStrifeTextureData(byte[] b)

Scans through texture lump data in order to detect whether it is for Strife or not.

Parameters:

b - the texture lump data.

Returns:

true if it is Strife texture data, false if not.

createTextureCopier

public static TextureUtils.TextureCopier createTextureCopier(Wad sourceWad,
 Wad destinationWad)
                                                      throws IOException

Creates a texture copier object for moving one or more textures (and associated data) to another Wad.

NOTE: Make sure you call TextureUtils.TextureCopier.close() on the copier so that the TEXTUREx/PNAMES entries get written properly.

Parameters:

sourceWad - the source Wad.

destinationWad - the destination Wad.

Returns:

the new copier.

Throws:

TextureException - if the source or destination does not have TEXTUREx or a PNAMES lump.

IOException - if a read error happens.
