Hello

Its been about 11 years since I have used adobe illustrator (AI) It was for manipulating simple black and white images. I used to be able to convert these images so that every line and dot of the image had those little (blue) lines and anchor points that enabled you to manipulate each and every area of the drawing. I seem to remember having to use a separate software from AI for this. I have tried in AI going to 'object' then 'rasterize' but with no luck… Can anyone advise?
Many thanks, Mark
