PS是一款栅格图像编辑软件，具有许多强大的功能，本文演示如何通过脚本实现逆时针旋转90度、旋转180度和顺时针旋转90度相关功能，展示从互联网收集而来的一个小插件，供大家学习交流，请勿用于商业用途。

本文界面是一系列功能的一部分，将逐步展示，但是功能界面是共同的，如下图所示：
2.关键代码
2.1 逆时针旋转90度
大家可通过源代码阅读，来掌握相关技巧，源代码如下：
//
//==================== Rotate <=90 ==============
//
function Rotate__90() {
// Rotate
function step1(enabled, withDialog) {
if (enabled != undefined && !enabled)
return;
var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
var desc1 = new ActionDescriptor();
var ref1 = new ActionReference();
ref1.putEnumerated(PSClass.Document, PSType.Ordinal, PSEnum.First);
desc1.putReference(PSString.Null, ref1);
desc1.putUnitDouble(PSKey.Angle, PSUnit.Angle, -90);
executeAction(PSEvent.Rotate, desc1, dialogMode);
};
step1(); // Rotate
};
cTID = function (s) {
return app.charIDToTypeID(s);
};
sTID = function (s) {
return app.stringIDToTypeID(s);
};
//
// Rotate__90.loadSymbols
// Loading up the symbol definitions like this makes it possible
// to include several of these generated files in one master file
// provided a prefix is specified other than the default. It also
// skips the definitions if PSConstants has already been loaded.
//
Rotate__90.loadSymbols = function () {
var dbgLevel = $.level;
$.level = 0;
try {
PSConstants;
return; // only if PSConstants is defined
} catch (e) {
} finally {
$.level = dbgLevel;
}
var needDefs = true;
$.level = 0;
try {
PSClass;
needDefs = false;
} catch (e) {
} finally {
$.level = dbgLevel;
}
if (needDefs) {
PSClass = function () {
};
PSEnum = function () {
};
PSEvent = function () {
};
PSForm = function () {
};
PSKey = function () {
};
PSType = function () {
};
PSUnit = function () {
};
PSString = function () {
};
}
// We may still end up duplicating some of the following definitions
// but at least we don't redefine PSClass, etc... and wipe out others
PSClass.Document = cTID('Dcmn');
PSEnum.First = cTID('Frst');
PSEvent.Rotate = cTID('Rtte');
PSKey.Angle = cTID('Angl');
PSString.Null = sTID('null');
PSType.Ordinal = cTID('Ordn');
PSUnit.Angle = cTID('#Ang');
};
Rotate__90.loadSymbols(); // load up our symbols
//=========================================
// Rotate__90.main
//=========================================
//
Rotate__90.main = function () {
Rotate__90();
};
Rotate__90.main();
// EOF
2.2 旋转180度
大家可通过源代码阅读，来掌握相关技巧，源代码如下：
//

//
//
//==================== Rotate 180 ==============
//
function Rotate180() {
// Rotate

if (enabled != undefined && !enabled)
return;
var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
var desc1 = new ActionDescriptor();
var ref1 = new ActionReference();
ref1.putEnumerated(PSClass.Document, PSType.Ordinal, PSEnum.First);
desc1.putReference(PSString.Null, ref1);
desc1.putUnitDouble(PSKey.Angle, PSUnit.Angle, 180);
executeAction(PSEvent.Rotate, desc1, dialogMode);
};
step1(); // Rotate
};
cTID = function (s) {
return app.charIDToTypeID(s);
};
sTID = function (s) {
return app.stringIDToTypeID(s);
};
//
// Rotate180.loadSymbols
// Loading up the symbol definitions like this makes it possible
// to include several of these generated files in one master file
// provided a prefix is specified other than the default. It also
// skips the definitions if PSConstants has already been loaded.
//
Rotate180.loadSymbols = function () {
var dbgLevel = $.level;
$.level = 0;
try {
PSConstants;
return; // only if PSConstants is defined
} catch (e) {
} finally {
$.level = dbgLevel;
}
var needDefs = true;
$.level = 0;
try {
PSClass;
needDefs = false;
} catch (e) {
} finally {
$.level = dbgLevel;
}
if (needDefs) {
PSClass = function () {
};
PSEnum = function () {
};
PSEvent = function () {
};
PSForm = function () {
};
PSKey = function () {
};
PSType = function () {
};
PSUnit = function () {
};
PSString = function () {
};
}
// We may still end up duplicating some of the following definitions
// but at least we don't redefine PSClass, etc... and wipe out others
PSClass.Document = cTID('Dcmn');
PSEnum.First = cTID('Frst');

// EOF
