Hi, Thanks a lot, Mr. Rosenthol! So, do you mean that the AICB is not "private to Adobe", that I could learn it? Well, I will download the Adobe Illustrator SDK. So, besides trying to learn AICB, my only remaining question is: Is it possible to read the array of CubicCurve2D.Double"s and the stroke and fill informations from a pdf graphics file of curves? This is probably a question for someone else. Thanks in advance for responding. >Is it possible to read the array of CubicCurve2D.Double's >and the stroke and fill information from a pdf graphics file of >curves?
