Pen size units:  Choose inches, millimeters (mm), points, or picas to specify how you want to measure pen size in the Pen tab of the Strokes palette. Number format:  Set the precision and numerical format for numbers in the Status bar, Type palette, Show Size display, and other numerical displays. You can choose whole integers, up to four-deci- mal precision, or fractions. The setting affects the measurement pre- cision only and does not affect the drawing precision. Virtual memory preferences (Mac OS 9.X) The Virtual preference lets you choose a disk drive and set other options for memory management. The memory management feature in Canvas makes it possible to open images and files that require more memory than the amount provided by physical RAM. Disk Drive:  Choose a mounted hard disk in the pop-up menu. Canvas uses this disk for virtual memory. The amount of available space on the disk is shown below the pop-up menu. Use available system memory:  Turning this option on instructs Canvas to use the allocated system memory first before resorting to its internal virtual memory. Dynamic Disk Allocation:  Leave this option on to let Canvas claim and release disk space as needed and available for particular files. If you turn this option off, you can use the “Minimum disk space after allocation” text box to set a limit on how much space Canvas can claim for virtual memory; e.g., if you type 50 in the text box, Canvas leaves at least 50 MB free on the disk. User Info preferences The User Info preference lets you specify a name and initials for object comments, which you can insert using the Comments com- mand (see “Attaching comments to objects,” page 16.286). Name:  Type a name in the text box. When you attach a com- ment to an object, Canvas associates the name you enter with the comment. By default, Canvas uses the name entered when Canvas was installed. Initials:  Type initials in the text box. When you attach com- ments to an object, Canvas associates these initials with the com- ment.
