> PDImageXObject should contain the method getColorSpaces() to get the color spaces that were passed to the constructor. I need it for the following use case:
> An image XObject may contain alternate images in the Alternates dictionary entry. I want to create an PDImageXObject for one of the alternate images, so I need the color spaces to pass them to the constructor. Theoretically a method that returns a list of PDImageXObjects containing all alternate images would also be possible. But as long as a PDImageXObject is always decoded it would produce unnecessary overhead as I only need one of them.
