Create multilayer PDF file

[OleksiyZ]

Hi,

Is it possible to create PDF file which will contain several layers, using ImageMagick API or cmd tools?
For example:
I have three tiff images: 1-layer.tiff, 2-layer.tiff and 3-layer.tiff. I need to create a PDF document which will contain one page and three layers, one layer for each tiff image.
I tried to use CompositeLayers but after writing to file resulted PDF will contain one layer and all images will be merged.

Thanks in advance for any help!
