5. 1 2 1 Scaling A few layout pictures are drawn full size Most are drawn less than full size typically to half scale To make the pictures fit your document neatly you may wish to change the scale The command setlayoutscale frac where frac is a decimal number e g 0 75 sets the scaling For example setlayoutscale 0 5 will produce pictures at half full size and setlayoutscale 1 0 will make the pictures full size 1 2 2 Layout types In general two kinds of layout pictures can be produced 1 A picture showing a generic layout and its controlling parameters is produced by a command of the form Ldiagram The same effect may be achieved by using a drawL after the declaration drawparameterstrue 2 A picture showing an actual layout is produced by a command of the form Ldesign The same effect may be achieved by using a drawL after the declaration drawparametersfalse Warning If an actual layout differs too much from a normal layout then LaTeX may hiccup a time or two The typical problem is when a dimension that is expected to be positive is actually negative LaTeX will respond with an error message like Bad line or vector argument Note The Zdiagram and Zdesign commands were introduced in version 2 5 of the package The previous method of generating pictures via drawL and drawparameters is mainly retained for compatibility reasons Examples of both kinds of layout are shown later S
