AWTTextureDataback to summary
public AWTTextureData(final GLProfile glp, final int internalFormat, final int pixelFormat, final boolean mipmap, final BufferedImage image)

Constructs a new TextureData object with the specified parameters and data contained in the given BufferedImage. The resulting TextureData "wraps" the contents of the BufferedImage, so if a modification is made to the BufferedImage between the time the TextureData is constructed and when a Texture is made from the TextureData, that modification will be visible in the resulting Texture.

Parameters
glp:GLProfile

the OpenGL Profile this texture data should be created for.

internalFormat:int

the OpenGL internal format for the resulting texture; may be 0, in which case it is inferred from the image's type

pixelFormat:int

the OpenGL internal format for the resulting texture; may be 0, in which case it is inferred from the image's type (note: this argument is currently always ignored)

mipmap:boolean

indicates whether mipmaps should be autogenerated (using GLU) for the resulting texture

image:BufferedImage

the image containing the texture data
