For no repeat:
http://www.khronos.org/opengles/documentation/opengles1_0/html/glTexParameter.html
and look at GL_CLAMP.
Texture y-coordinates go from the bottom to the top when y increases.
Bitmaps/images usually go from the top to the bottom when y increases.
Just flip your bitmap along the y-axis.
