How to create JPEG image on iOS from scratch

I'm trying to create an objective C classe for my iPad application which can convert a powerpoint file to a jpeg file. Accordingly i've to read into the pptx format to see how the file is structured and create an image, from scratch, in which i can say this element goes there, this one here, this text there.

But actually i've no idea how to do this, if the best way is to use a already existing framework in iOS or an additional library?

Thanks to everyone ;)

Bye

Take a look at Quartz 2D, the drawing engine used as the main workhorse for 2D graphics on iOS. It gives you all the primitives for drawing shapes, fills, text and other objects you need to render the presentation.

The fastest way to visualize elements is, to me, OpenGL ES. You can use mobile GPU to visualize then there is CIImage for managing image.
