I have installed a trial of Adobe illustrator on my macbook pro. It is the 2014 release of adobe illustrator. I want to trace an image using the custom trace button.
I start a new document. Then I place my scanned pencil/colored pencil drawing, in to the document. I have tried scanning and then placing it as a jpeg, bitmap, and tiff file. I have tried scanning and then placing it, in color and in black and white. The scan mode I use is flatbed. Adobe illustrator allows me to select the default button and one of eleven preset buttons (e.g high fidelity photo), but it does not allow me to click the custom trace button. The custom trace button is grey while all the other buttons are white.
Does anyone have any ideas how I could custom trace?
