Along with the specification documents and code, we have collected sample images for many of the graphics file formats. You can use these sample images to test whether you are successfully reading or converting a particular file format.
As we mentioned in a previous section, the online product also provides an Image Lab offering graphics demos that will let you view, compare, and compress images of different types, sizes, and depths.
