JSX（Photoshop） - dpi中的文档分辨率

Question

我正在使用Photoshop中的jsx脚本将图像大小调整为特定大小。分辨率设置为200 dpi。运行脚本后，我可以在Image＆gt;下查看图像尺寸。

问题是，根据图像，它最初倾向于以点/厘米而不是点/英寸显示分辨率。数字本身无论如何都是正确的，但我希望看到它作为后者提到它。有没有办法在JSX中实现这一点？

谢谢！

The easy way is to open your Info Panel by going to Window > Info, and then click on the x/y coordinates dropdown in the Info Panel and select inches. The dropdown is the + toward the lower-left of the panel, with the little down arrow at the bottom right of the + symbol (The plus is actually an x axis and y axis representing a coordinate plane). After that, when you check under Image > Image Size, it should show you all information in inches instead of centimeters. This should also show you inches anywhere else you look in Photoshop's interface, too, such as the rulers.

An exception would be that when using selection tools, such as the marquee tool with a setting like "fixed size" selected, you can override the units setting by typing in another unit in the Width and Height sections at the top of the window. You can even mix and match units, making a precise selection that is, for example, exactly 250 pixels (px in the Width setting) by 30 points (pt in the Height setting). And when you check your image size, it should still show you results in inches.

And finally, to answer your question as it was asked, the following code will change your rulerUnits preference without opening the Info Panel.

#target Photoshop
preferences.rulerUnits = Units.INCHES;

Note that if you want to write other scripts, you can change the rulerUnits to whatever units the script calls for, and then at the end of the script put your units back the way you had them.

#target Photoshop

// Save the original rulerUnits setting to a variable
var originalRulerUnits = preferences.rulerUnits;

// Change the rulerUnits to Inches
preferences.rulerUnits = Units.INCHES;

//
// Do magical scripty stuff here...
//

// Restore the original setting
preferences.rulerUnits = originalRulerUnits;

// List of rulerUnits settings available
// Units.CM
// Units.INCHES
// Units.MM
// Units.PERCENT
// Units.PICAS
// Units.PIXELS
// Units.POINTS
