public class TextureData extends Object
Represents the data for an OpenGL texture. This is separated from the notion of a Texture to support things like streaming in of textures in a background thread without requiring an OpenGL context to be current on that thread.- Author:

Constructs a new TextureData object with the specified parameters and data contained in the given Buffer. The optional Flusher can be used to clean up native resources associated with this TextureData when processing is complete; for example, closing of memory-mapped files that might otherwise require a garbage collection to reclaim and close.- Parameters:
glp

- the number of pixels of border this texture data has (0 or 1)pixelFormat
- the OpenGL pixel format for the resulting texture; must be specified, may not be 0pixelType
- the OpenGL type of the pixels of the texturemipmap
- indicates whether mipmaps should be autogenerated (using GLU) for the resulting texture. Currently if mipmap is true then dataIsCompressed may not be true.dataIsCompressed
- indicates whether the texture data is in compressed form (e.g. GL_COMPRESSED_RGB_S3TC_DXT1_EXT)mustFlipVertically
- indicates whether the texture coordinates must be flipped vertically in order to properly display the texturebuffer
- the buffer containing the texture dataflusher
- optional flusher to perform cleanup tasks upon call to flush()- Throws:
IllegalArgumentException
