------- Comment #4 from [EMAIL PROTECTED] 2007-11-28 05:12 PST -------
Brian, Ian,
Thanks for the comments. Please note, that I am referring to glTexSubImage2D()
and not to glCompressedTexSubImage(), you cited in the reply.
The extension specification says, as far as the former function is concerned,
that the width, height *don't* have to ba a multiple of four, *if* xoffset =
yoffset = 0:
* <width> is not a multiple of four or equal to TEXTURE_WIDTH,
unless <xoffset> and <yoffset> are both zero.
I think the teximage.c:subtexture_error_check2(), called in glTexSubImage2D(),
discriminates the above case. What is your opinion?
(To summarize: texture is loaded and compressed via glTexImage2D(), and
modified via glTexSubImage2D().)
