Reading image layers

Hi guys,

I am developing an application to read an image format and convert it to my
proprietary format. I want to read/get the layer information of the image, each
graphic object associated with the image.

I downloaded CS SDK but unable to identify the component/APIs. Can you please
help me in identifying the same.

Thanks in advance

So, you are looking to automate Photoshop from your application, to
have it do the task? Or you're looking to add on a Photoshop format
plug-in to have it export to your proprietary format (which sounds a
better fit for the SDK).

...or do you want to passively parse PSD?

I want to read Bartender (CD labelling image) format and create my own CD label
image. Photoshop is able to load the bartender file and also allows to get the
layers from it.
So, I thought I could use photoshop SDK to load the file and get the graphic
information from the file and create my own format.

Maybe you can use the Photoshop SDK, but you don't make it clear
whether you completely understand what the SDK is. It is a set of
tools for adding on to Photoshop, or automating Photoshop. 

The "obvious" way to do this is to add an export module to Photoshop,
so people can save anything open in Photoshop into your file format. 

What do you mean by "graphic information", though - do you just mean
the raster images of each layer?
