Dear All:
I have a doubt about precondition of _mesa_adjust_image_for_convolution()
usage.The current version of Mesa core I was reading is 7.0.3
In _mesa_TexImage2D, we will call _mesa_adjust_image_for_convolution() to
caculate postConvWidth and postConvHeight to pass to
_mesa_init_teximage_fields() if and only if the condition
is_color_format(internalformat) satisfied, but after a while, when we call into
the default driver->TexImage2D() which always is _mesa_store_teximage2d(), we
will find that only if the IMAGE_CONVOLUTION_BIT bit is set in
ctx->_ImageTransferState field, we will caculate postConvWidth and
postConvHeight via _mesa_adjust_image_for_convolution() function, then use the
postConv* width and height to caculate the buffer size. I think that the two on
and on _mesa_adjust_image_for_convolution() calling path are not consistency,
the texImage->Width2 and texImage->Heigth2 will be not consistency with
allocated texture buffer size yet.
Anybody can point for me what's wrong in my understanding? Thanks very much!
Regards
Westermann
