Constructor Detail

Texture2D

public Texture2D()
Constructs a texture object using default values. The default values are as follows:

Note that the default constructor creates a texture object with a width and height of 0 and is, therefore, not useful.


Texture2D

public Texture2D(int mipMapMode,
                 int format,
                 int width,
                 int height)
Constructs an empty Texture2D object with specified mipmapMode format, width and height. Image at base level must be set by the application using 'setImage' method. If mipmapMode is set to MULTI_LEVEL_MIPMAP, images for base level through maximum level must be set.

Parameters:
mipMapMode - type of mipmap for this Texture: One of BASE_LEVEL, MULTI_LEVEL_MIPMAP.
format - data format of Textures saved in this object. One of INTENSITY, LUMINANCE, ALPHA, LUMINANCE_ALPHA, RGB, RGBA.
width - width of image at level 0. Must be power of 2.
height - height of image at level 0. Must be power of 2.
Throws:
java.lang.IllegalArgumentException - if width or height are NOT power of 2 OR invalid format/mipmapMode is specified.

Texture2D

public Texture2D(int mipMapMode,
                 int format,
                 int width,
                 int height,
                 int boundaryWidth)
Constructs an empty Texture2D object with specified mipMapMode, format, width, height, and boundaryWidth. Defaults are used for all other parameters. If mipMapMode is set to BASE_LEVEL, then the image at level 0 must be set by the application (using either the setImage or setImages method). If mipMapMode is set to MULTI_LEVEL_MIPMAP, then images for levels Base Level through Maximum Level must be set.

Parameters:
mipMapMode - type of mipmap for this Texture: one of BASE_LEVEL, MULTI_LEVEL_MIPMAP
format - data format of Textures saved in this object. One of INTENSITY, LUMINANCE, ALPHA, LUMINANCE_ALPHA, RGB, RGBA
width - width of image at level 0. Must be power of 2. This does not include the width of the boundary.
height - height of image at level 0. Must be power of 2. This does not include the width of the boundary.
boundaryWidth - width of the boundary.
Throws:
java.lang.IllegalArgumentException - if width or height are not a power of 2, if an invalid format or mipMapMode is specified, or if the boundaryWidth < 0
