Choosing line joins and end caps Pop-up menus in the Pen manager let you specify the type of line joins and end caps. Line joins determine appearance of two path seg- ments that meet at a corner. End caps specify the shape of the end- points of an open path. Line joins Canvas has three types of line joins: miter, round, and bevel. For pre- set pen strokes, Canvas indicates the type of line join in the scroll list on the Pen tab. Miter    Joins path segments with sharp corners that extend to a single point. When you choose miter joins, an additional pop-up menu lets you set the miter limit in degrees (5, 10, 30, 60, or 90 degrees). The miter limit setting tells Canvas which corners are too tight to miter; Canvas bevels these corners instead. In other words, if the miter limit is set to 10 degrees, and two path segments join at an angle of 9 degrees, Canvas bevels the corner rather than creating a miter join. The miter limit lets you prevent long, spiked corners that might result as a combination of a wide pen size and a small angle. Pen manager These settings let you create Calligraphic pen types. A    Choose Calligraphic in the pop-up menu. B    Specify weight, width, and angle of the pen nib. You can set the units of measure for these settings using the Prefer- ences command in the File menu. C   Configure line joins and end caps using the pop-up menus; see the next section for informa- tion on these settings. D   Sample window of the cur- rent pen settings. E    Edit the size and angle of the nib interactively in this edit window (see inset). F    Use the zoom buttons to in- crease or reduce the size of the nib in the edit window. This does not affect the actual pen size. In the edit window, you can drag control points to adjust the pen nib. G   Drag to change the width and angle of the nib. H   Drag to change the weight and angle of the nib. A B D C G H E F
