• Using this instruction without a parameter field turns the scaling off.
• Type can be 0, 1 or 2, which select scaling types known as anisotropic, isotropic and point factor scaling
respectively.
• Type 0 scaling (anisotropic scaling, the default) allows you to specify different sized x-axis and y-axis units.
Hence the area specified by X
• left and bottom settings have no effect in type 0 scaling.
• Type 1 scaling (isotropic scaling) forces x-axis and y-axis units to be the same size.
