after you perform image trace, you can choose to view outlines. how can you perform a stroke or basically make those outlines to be lines. thanks for any help. i'm a beginner in illustrator by the way. so I need detailed instructions lol
You cannot work with the outlines as they are. The Control Panel or the Properties panel (Window menu > Control or Window > Properties) should show you an Expand button. Click it. A look in the Layers panel will show that the image is now a Group of paths and/or compound paths. You can select these individually in the Layers panel, or select them on the Artboard with the Group Selection Tool or the Direct Selection Tool; or Object > Ungroup to select with the Selection Tool. In any case, you can now apply strokes and fills to the paths.
If necessary, please ask further questions. If your device is capable of producing screenshots, please use that to furnish images: camera shots of screens are hard to look at, especially as a diagnostic tool. Thanks!
