In the pdf file structure, I can found the following:
/Colorspace 49
/Colorspace 50
/Colors 3
/DecodeParms Predictor 15
connected to image subtypes.
What do mean the words above?
Thank you,
Isabella

I solved, in some cases the color palette was coded in another object, in other I have to use the png decription algorithm.
