In image informations, the PDF is seen as RGB. * convert INVIT_210x100_Vide.pdf -set colorspace CMYK -colorspace RGB x: The image is displayed correctly. In image informations, the PDF has 2 colorspace, The first is RGB, and there is RGB color informations. The second is CMYK, and there is no color informations.
