Note:
Defining the Area of a Selection Object
To define the area of a selection object, we will create an array of coordinates, or points specified in pixels
within the document. The array indicates the coordinates that define the outside corners of a rectangular
area that begins at the top left corner of the document and extends half way across the document.
Note: You can define any number of points for a selected area. The number of coordinates determines the
shape of the selection. The last coordinate defined must be the same as the first so that the area.
Note: See
other Photoshop CS2 objects.
The array values in order are:
Upper left corner of the selection:
●
indicates the left-most column in the document.
● 0
indicates the top row in the document.
● 0
Upper right corner of the selection:
●
● theDocWidthInPixels / 2
column whose coordinate is the total number of columns in the document divided by 2.
Note:
indicates the top row in the document.
● 0
Lower right corner:
●
● theDocWidthInPixels / 2
● theDocHeightInPixels
is the total number of rows in the document.
Note:
Lower left corner:
●
theDocWidthInPixels / 2

To select an area and apply a wave filter to it:
1. Type the following code into the script file
restore original preferences:
--create new variables to contain the document object's width and height
--determine width and height values by multiplying the
--width and height in inches by the resolution
--(which equals the number of pixels per inch)
The wave is a truncated sine curve.
