photoshop plugin SDK 调用旋转功能 c++

调用 Photoshop Plugin SDK 中的旋转功能需要使用 PISuites.h 头文件中的函数。具体步骤如下：

1. 引入头文件

#include "PISuites.h"

2. 获取 SPBasicSuite 指针

SPBasicSuite *sSPBasic = NULL;
if (sSPBasic == NULL) {
    error = sSPBasicAcquire(&sSPBasic);
}

3. 获取 SPPluginRef 对象

SPPluginRef pluginRef = NULL;
error = sSPBasic->AcquireSuite(kSPPluginSuite, kSPPluginSuiteVersion, (const void **)&pluginRef);

4. 获取 SPSActionControlSuite 对象

SPSActionControlSuite *sSPSActionControl = NULL;
error = sSPBasic->AcquireSuite(kSPSActionControlSuite, kSPSActionControlSuiteVersion, (const void **)&sSPSActionControl);

5. 设置旋转参数

SPActionReference actionRef = NULL;
SPActionDescriptor actionDesc = NULL;
SPActionDescriptor resultDesc = NULL;
char *rotateMode = "byAngle";
double rotateAngle = 30.0;

actionRef = sSPSActionControl->NewActionReference();
error = sSPSActionControl->PutEnumerated(actionDesc, kSPHostAutoInterp, kSPRotateTool, kSPRotateTool);
error = sSPSActionControl->PutEnumerated(actionDesc, kSPHostAutoInterp, kSPByAbsolute, kSPByAbsolute);
error = sSPSActionControl->PutUnitFloat(actionDesc, kSPHostAutoInterp, kSPAngleUnit, rotateAngle);

6. 调用旋转功能

error = sSPSActionControl->Play(actionRef, actionDesc, kDialogOff, &resultDesc);

完整代码示例：

#include "PISuites.h"

int main(int argc, char **argv) {
    SPErr error = kSPNoError;

    // 获取 SPBasicSuite 指针
    SPBasicSuite *sSPBasic = NULL;
    if (sSPBasic == NULL) {
        error = sSPBasicAcquire(&sSPBasic);
    }

    // 获取插件引用
    SPPluginRef pluginRef = NULL;
    error = sSPBasic->AcquireSuite(kSPPluginSuite, kSPPluginSuiteVersion, (const void **)&pluginRef);

    // 获取 SPSActionControlSuite 对象
    SPSActionControlSuite *sSPSActionControl = NULL;
    error = sSPBasic->AcquireSuite(kSPSActionControlSuite, kSPSActionControlSuiteVersion, (const void **)&sSPSActionControl);

    // 设置旋转参数
    SPActionReference actionRef = NULL;
    SPActionDescriptor actionDesc = NULL;
    SPActionDescriptor resultDesc = NULL;
    char *rotateMode = "byAngle";
    double rotateAngle = 30.0;

    actionRef = sSPSActionControl->NewActionReference();
    error = sSPSActionControl->PutEnumerated(actionDesc, kSPHostAutoInterp, kSPRotateTool, kSPRotateTool);
    error = sSPSActionControl->PutEnumerated(actionDesc, kSPHostAutoInterp, kSPByAbsolute, kSPByAbsolute);
    error = sSPSActionControl->PutUnitFloat(actionDesc, kSPHostAutoInterp, kSPAngleUnit, rotateAngle);

    // 调用旋转功能
    error = sSPSActionControl->Play(actionRef, actionDesc, kDialogOff, &resultDesc);

    return error;
}
