Hi, I'm trying to load a "npot" bitmap into a GL_TEXTURE_RECTANGLE_ARB texture, but clearly i'm missing something becouse the drawing gets all wierd in the screen(it works fine with "pot" images). Can somebody help me? *MSV 2003 project http://www.inf.ufsc.br/~vilsonhj/tex_arb.rar With images like 360x240 and 1024x768 the program displays it FINE. However, with an image of 407x369 Shocked check it out: http://www.geocities.com/karl_phillip/npot.JPG

*Problem solved*

I didn't know I had to "disable alignment of rows of source data" using glPixelStorei( GL_UNPACK_ALIGNMENT, 1 ) ;
