I am very beginning to OpenGl.I want to load a map in a gluperspective projection using openGL in MFC MDI application .I create rendering context and set a pixel format in to the current context. when i am zooming that map at that time it should be clear vision. so which format of file i include?(BMP,JPEG ). How do i do?
consider my problem.

Let me rephrase your needs : 1) you want to create a texture by reading an image file, 2) then display it on a textured quad.
For 1), the image file reading part is not related to opengl. you may use an existing image library (freeimage,…) or do you own (harder). Then create a texture and dump the decoded image data in it.
