Scale

Scale[g,s]

represents graphics primitives g scaled by a factor s.

Scale[g,s,{x,y,…}]

scales with the point {x,y,…} kept fixed.

Scale[g,{sx,sy,…},…]

scales by different factors along different axes.

Details

  • Scale[g,s] scales with the center of the bounding box of g kept fixed.
  • You can specify special points such as {Left,Bottom} within the bounding box for g to be kept fixed.
  • The x position can be specified as Left, Center, or Right; the y position as Bottom, Center, or Top.
  • Explicit coordinates {x,y} are taken to be in the coordinate system of the graphic in which Scale[…] appears.
  • For objects specified with scaled coordinates Scaled[{x,y}], Scale effectively applies its transformation to the corresponding ordinary coordinates.
  • Scale can modify the regions allocated to Text and Inset objects, but does not directly affect their contents, and does not scale fonts or other textual elements. »
  • Normal[expr] if possible replaces all Scale[gi,…] constructs by versions of the gi in which the coordinates have explicitly been transformed.

The size of text is affected by Scale only when it is specified using Scaled:

Properties & Relations  (1)

When possible, Normal will transform the coordinates explicitly:

Possible Issues  (1)

By default, scaling in 2D is done to keep the center of the bounding box fixed:

Explicitly set the origin to be fixed:
