Image scaling (KeepAspectRatioByExpanding) through OpenGL

http://stackoverflow.com/questions/9011108/image-scaling-keepaspectratiobyexpanding-through-opengl

I'm trying to implement image scaling in OpenGL using only glTexCoord2f and glVertex2f . Let me explain after loading a QImage and sending.. coordinates to flip the image vertically glBegin GL_QUADS glTexCoord2f 0.0f img_height glVertex2f offset_x gl_height offset_y glTexCoord2f.. 0.0f img_height glVertex2f offset_x gl_height offset_y glTexCoord2f img_width img_height glVertex2f gl_width offset_x gl_height..
