Adobe Smoke Alarm CS3 Manual De Usuario

 Scripting Photoshop CS3     52

The following script, which assumes an RGB color model, gets the foreground color and then uses the 

convert

 command of the 

color

 class to convert the color to its CMYK equivalent.

get foreground color
convert color foreground color to CMYK

Look up the following in the Adobe Photoshop CS3 AppleScript Scripting Reference or in the Photoshop CS3 
AppleScript Dictionary:

●

In the “Objects” section, the 

foreground color

 property of the class 

application

●

In the “Commands” section, 

convert

The following script uses an 

If Then

 statement and the 

model

 property of the 

SolidColor

 object to 

determine the color model in use. The 

If Then

 statement returns a 

SolidColor

 object; if it returns an 

RGB

 

object, the 

cmyk

 property of the 

SolidColor

 object then allows you to access the color with its CMYK 

equivalent. 

Dim someColor 
If (someColor.model = 2) Then

someColor.cmyk
'someColor.model = 2 indicates psColorModel --> 2 (psRGBModel)

End If

Look up the following in the Adobe Photoshop CS3 Visual Basic Scripting Reference, or in the Visual Basic 
Object Browser:

●

model

 and 

cmyk

 as properties of the 

SolidColor

 object

This example uses the 

foregroundColor

 property of the 

Application

 object to get the original color to 

be converted. The 

cmyk

 property of the 

SolidColor

 object that 

foregroundColor

 refers to provides a 

way to access the cmyk equivalent of the rgb color.

var someColor = foregroundColor.cmyk

Look up the following in the Adobe Photoshop CS3 JavaScript Scripting Reference, or in the ExtendScript 
Object Model Viewer:

●

cmyk

 as a property of the 

SolidColor

 object

●

foregroundColor

 as a property of the 

Application

 object

Using the 

equal colors (IsEqual/isEqual)

 command, you can compare colors. The following 

statements return 

true

 if the foreground color is visually equal to background color. 

●

AS: 

if equal colors foreground color with background color then

●

VBS: 

If (appRef.ForegroundColor.IsEqual(appRef.BackgroundColor)) Then

●

JS: 

if (app.foregroundColor.isEqual(backgroundColor))

 

To convert a color to a web safe color use the 

web safe color

 command on AppleScript and the 

NearestWebColor/nearestWebColor

 property of the 

SolidColor

 object for VBScript and JavaScript.
