TextureWriters know how to write - TextureData objects to disk in various file formats. The - TextureData class represents the raw data of the texture before it - has been converted to an OpenGL texture object. The Texture class - represents the OpenGL texture object and provides easy facilities - for using the texture. </P> - - <P> There are several built-in TextureProviders and TextureWriters - supplied with the TextureIO implementation. The most basic - provider uses the platform's Image I/O facilities to read in a - BufferedImage and convert it to a texture. This is the baseline - provider and is registered so that it is the last one consulted. - All others are asked first to open a given file. </P> - - <P> There are three other providers registered by default as of - the time of this writing. One handles SGI RGB (".sgi", ".rgb") - images from both files and streams. One handles DirectDraw Surface - (".dds") images read from files, though can not read these images - from streams. One handles Targa (".tga") images read from both - files and streams. These providers are executed in an arbitrary - order. Some of these providers require the file's suffix to either - be specified via the newTextureData methods or for the file to be - named with the appropriate suffix. In general a file suffix should - be provided to the newTexture and newTextureData methods if at all - possible. </P> - - <P> Note that additional TextureProviders, if reading images from - InputStreams, must use the mark()/reset() methods on InputStream - when probing for e.g. magic numbers at the head of the file to - make sure not to disturb the state of the InputStream for - downstream TextureProviders. </P> - - <P> There are analogous TextureWriters provided for writing - textures back to disk if desired. As of this writing, there are - four TextureWriters registered by default: one for Targa files, - one for SGI RGB files, one for DirectDraw surface (.dds) files, - and one for ImageIO-supplied formats such as .jpg and .png. Some - of these writers have certain limitations such as only being able - to write out textures stored in GL_RGB or GL_RGBA format. The DDS - writer supports fetching and writing to disk of texture data in - DXTn compressed format. Whether this will occur is dependent on - whether the texture's internal format is one of the DXTn - compressed formats and whether the target file is .dds format. -*/ - -public class TextureIO { - /** Constant which can be used as a file suffix to indicate a - DirectDraw Surface file. */ - public static final String DDS = "dds"; - - /** Constant which can be used as a file suffix to indicate an SGI - RGB file. */ - public static final String SGI = "sgi"; - - /** Constant which can be used as a file suffix to indicate an SGI - RGB file. */ - public static final String SGI_RGB = "rgb"; - - /** Constant which can be used as a file suffix to indicate a GIF - file. */ - public static final String GIF = "gif"; - - /** Constant which can be used as a file suffix to indicate a JPEG - file. */ - public static final String JPG = "jpg"; - - /** Constant which can be used as a file suffix to indicate a PNG - file. */ - public static final String PNG = "png"; - - /** Constant which can be used as a file suffix to indicate a Targa - file. */ - public static final String TGA = "tga"; - - /** Constant which can be used as a file suffix to indicate a TIFF - file. */ - public static final String TIFF = "tiff"; - - private static final boolean DEBUG = Debug.debug("TextureIO"); - - // For manually disabling the use of the texture rectangle - // extensions so you know the texture target is GL_TEXTURE_2D; this - // is useful for shader writers (thanks to Chris Campbell for this - // observation) - private static boolean texRectEnabled = true; - - //---------------------------------------------------------------------- - // methods that *do not* require a current context - // These methods assume RGB or RGBA textures. - // Some texture providers may not recognize the file format unless - // the fileSuffix is specified, so it is strongly recommended to - // specify it wherever it is known. - // Some texture providers may also only support one kind of input, - // i.e., reading from a file as opposed to a stream. - - /** - * Creates a TextureData from the given file.
