The opengles library, i m using doesnt support the glGetTexImage function,
what are the other ways to get the image of texture ?

EDIT : I misread your post.

What version of ES are you on?
What are you trying to do?
Perhaps glReadPIxels may be of use?

But do be very aware, due to the nature of most ES GPUs, any kind of texture access mid-frame is very very bad practice and will cause slow downs. This may be part of the reason glGetTexImage is not available.

This may also be of use to you..
