Numerical transformations

To track your transformations numerically, display the Info palette (F8) before you apply the Free Transform command. Even after you initiate Free Transform, you can access the Info palette by choosing Window S Show Info.

You can also track the numerical equivalents of your transformations in the Options bar. Shown in Figure 12 31, the Options bar contains a series of numerical transfer mation controls anytime you enter the Free Transform mode. These values not only reflect the changes you've made so far, but also permit you to further transform the selection or layer numerically.

Figure 12-31: Normally, the options in the Options bar change only when you select a different tool, but choosing Free Transform adds a series of controls that permit you to transform a selection or layer numerically.

For the most part, the controls in the Options bar are straightforward. Click in the grid of nine squares to reposition the transformation origin. Use the X and Y values to change the location of the origin numerically. Click the triangular delta symbol to measure the movement relative to the transformation origin. Use the W and H values to scale the selection or layer. Click the link button to constrain the W and H values and resize the selection or layer proportionally. The angle value rotates; t he H and V values skew.

I imagine most folks use the Options bar strictly for scaling and rotating. You'd need the spatial awareness of a NASA navigation system to predict a numerical slant.
