You use the x-axis to specify the horizontal position on the canvas.
●
You use the y-axis to specify the vertical position on the canvas.
●
The origin point in Photoshop CS2, that is, x-axis = 0 and y-axis = 0, is the upper left corner of the screen.
The opposite corner, the lower right, is the extreme point of the canvas. For example, if your canvas is 1000
x 1000 pixels, then the coordinate for the lower right corner is x-axis = 1000 and y-axis = 1000.
You specify coordinate points that describe the shape you want to select as an array, which then becomes

The following examples assume that the ruler units have been set to pixels and create a selection
by:
1. Creating a variable to hold a new document that is 500 x 500 pixels in size.
2. Creating a variable to hold the coordinates that describe the selected area (that is, the
object).
3. Adding an array as the selection variable's value.
4. Using the
