Public Methods
public
static
int
getInternalFormat(Bitmap bitmap)
return the internal format as defined by OpenGL ES of the supplied bitmap.
Returns
- the internal format of the bitmap.
public
static
int
getType(Bitmap bitmap)
Return the type as defined by OpenGL ES of the supplied bitmap.
public
static
void
texImage2D(int target, int level, int internalformat, Bitmap bitmap, int type, int border)
A version of texImage2D() that takes an explicit type parameter
as defined by the OpenGL ES specification.
public
static
void
texImage2D(int target, int level, int internalformat, Bitmap bitmap, int border)
Calls glTexImage2D() on the current OpenGL context. If no context is
current the behavior is the same as calling glTexImage2D() with no
current context, that is, eglGetError() will return the appropriate
error.
Unlike glTexImage2D() bitmap cannot be null and will raise an exception
in that case.
All other parameters are identical to those used for glTexImage2D().
NOTE: this method doesn't change GL_UNPACK_ALIGNMENT, you must make
sure to set it properly according to the supplied bitmap.
Whether or not bitmap can have non power of two dimensions depends on
the current OpenGL context. Always check glGetError() some time
after calling this method, just like when using OpenGL directly.

void
texImage2D(int target, int level, Bitmap bitmap, int border)
A version of texImage2D that determines the internalFormat automatically.
public
static
void
texSubImage2D(int target, int level, int xoffset, int yoffset, Bitmap bitmap, int format, int type)
A version of texSubImage2D() that takes an explicit type parameter
as defined by the OpenGL ES specification.
