image

Hi, i need to change the resolution of an image programmatically. I'm really noobiedoobie at resolutions and Dpi so i'm not sure how to go about it. I need to change the reolution on the camera image to 300Dpi. My idea is to do the calculations in photoshop and then shrink the image by drawing it in a smaller rect with cgcontext. I's this a clumsyway of doing it?
