I am making do a pdf-form, what customers can use to do printing order and also can attach their company logo file to same pdf-form. Logo is mostly jpeg-image. I noticed that it is possible to form user to attach RGB images, if I make Content Area at the form. But it is not possible attech CMYK-images. Although I attach RGB jpeg image to ready made form's Content area, it is not possible to get file out of form or save file again as a jpeg image from form afterwards.
