constructors

TclTexture2D(TclModule *m, unsigned int *b, const unsigned int nr, const unsigned int nc, Format f=TEXTURE_RGBA)

building a 2D texture from aRGBA or ARGB buffer

Parameters:

m - module to create TCL object
b - a buffer where each pixel is each coded with RGBA or ABGR
nr - the number of rows (may not be a power of 2)
nc - the number of columns (may not be a power of 2)
f - the format of each pixel

TclTexture2D(TclModule *m, char *filename)

build a 2D texture interface from a file

Parameters:

m - module to create TCL object
filename - file name of a GIF file

TclTexture2D(TclModule *m, Texture2D::GenericTexture type, const unsigned int size, const double exponent=1.0, const double radius=1.0)

build a 2D texture interface of a given type

Parameters:

the - type of generic texture
size - the number of rows and columns of the texture
exponent - for the gaussian and halo texture controls the spread of the gaussian
radius - for the halo texture controls the radius of the halo (as default it is a quarter of the size )

destructor
