2.8 The Scaler

The Scale menu  contains the following entries:

•   Make Larger (<Alt+L>). Scales the document. The drawing is made larger . Even the fonts are scaled when your X server supports scalable X fonts.
•   Make Smaller (<Alt+S>). Scales the document. The drawing is made smaller .
•   Normal Scale (<Alt+N>). Returns to normal view, i.e. no scaling.
•   Whole Drawing (<Alt+W>). Scales the document with a percentage that makes that the whole document fits to one page. The page size and orientation can be set in the Page menu.
•   Scale Factor. Set the scale factor with a pop-up slider dialog. The default scale factor is 1.2.

A slider dialog  is a dialog that is used to set an editor option from a subrange of values by adjusting a horizontal slider. For an example of a slider dialog see figure 2.8.

  The current scale percentage is always visible in the bottom-right corner of the main window and is updated by the scaling commands. The scale percentage is the  ratio between the TCM coordinates and the X Window coordinates, which is 100% when there is no scaling. By making the drawing larger you make this percentage larger, by making the drawing smaller, you make percentage smaller. The scale factor is the factor by which the scale percentage is increased or decreased during scaling. The scale percentage and factor are settings of the editor not of the document. So when a document is saved to file, the scale percentage and factor are not stored. But when the drawing is saved as PostScript or as EPSF, the output is scaled by the scale percentage.
