Specify columns for an image
Columns help you position images or elements precisely. The New, Image Size, and Canvas Size commands let you
specify image width in terms of columns. Using columns is convenient when you plan to import an image into a
page-layout program, such as Adobe InDesign®, and you want the image to fit exactly within a certain number of
columns.

Position with the Ruler tool
The Ruler tool
helps you position images or elements precisely. The Ruler tool calculates the distance between
any two points in the workspace. When you measure from one point to another, a nonprinting line is drawn, and the
options bar and Info palette show the following information:
•
The starting location (X and Y)
•
The horizontal (W) and vertical (H) distances traveled from the x and y axes
•
The angle measured relative to the axis (A)
•
The total length traveled (D1)
•
The two lengths traveled (D1 and D2), when you use a protractor
All measurements except the angle are calculated in the unit of measure currently set in the Units & Rulers preference
dialog box.
If your document has an existing measuring line, selecting the Ruler tool causes it to be displayed.
