To create a selection, you use the
You define a selection by specifying the coordinates on the screen that describe the selection's corners.
Since your document is a 2-dimensional object, you specify coordinates using the x-and y-axes as follows:

➤
You use the y-axis to specify the vertical position on the canvas.
The origin point in Photoshop, 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:
