I had get a Object on PDF,

PDEContent pdeContent = PDPageAcquirePDEContent(pdPage, gExtensionID);

PDEElement  pdeElement = PDEContentGetElem(pdeContent, 0);

Now, i want save this object to a image.

How can save a PDEElement to a image?

Thanks all!.

The same document you should already be using, plugin API.

OK, but that feature doesn't use PDE APIs to do the job.

But if you are doing that, then you can use simply coerce a PDEElement of type pdeImage to a PDEImage and use the appropriate APIs

The Acrobat SDK gives information on the PDEImage methods. You need to know how to recursively iterate the page descending into PDEContainers.

The SDK includes the PDF specification. Be sure you are familiar with the chapter "Graphics" as you must understand the graphics model, colour spaces etc. to use this API.

If you do not know about the different representations of image file formats (e.g. bits per compontent, pixel ordering, row and sample padding, compression, colour spaces, indexes etc.) you will need to some general study first.

Is your PDEElement a PDEImage? If so you can read the colour space, bits per component; read the pixels; convert to the representation needed by the image file format; write the image.

Can you give me a sample or document?

thanks.
