PDF 旋转

使用 PDF 旋转工具，您可以根据需要旋转 PDF 文件。以下示例展示了如何使用 Java、PHP、C#、Python 和 Swift 语言上传测试 PDF 文件并将 PDF 第 1~2 页旋转 90 度。然后输出旋转后的 PDF 文件。

Java

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a PDF rotate task
CPDFCreateTaskResult result = client.createTask(CPDFDocumentEditorEnum.ROTATION);

// Get a task id
String taskId = result.getTaskId();

// File handling parameter settings
CPDFPageRotationParameter fileParameter = new CPDFPageRotationParameter();
fileParameter.setPageOptions(Arrays.asList("1","2"));
fileParameter.setRotation("90");

// Upload files
client.uploadFile(new File("test.pdf"), taskId, fileParameter);

// Execute task
client.executeTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.getTaskInfo(taskId);

PHP

// Create a client
$client = new CPDFClient('public_key', 'secret_key');

// Create a task
// Create an example of a PDF rotate task
$taskInfo = $client->createTask(CPDFDocumentEditor::ROTATION);

// File handling parameter settings
$file = $client->addFile('test.pdf')
    ->setPageOptions(['1', '2'])
    ->setRotation('90');

// Upload files
$fileInfo = $file->uploadFile($taskInfo['taskId']);

// Execute task
$client->executeTask($taskInfo['taskId']);

// Query TaskInfo
$taskInfo = $client->getTaskInfo($taskInfo['taskId']);

C#

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a PDF rotate task
CPDFCreateTaskResult result = client.CreateTask(CPDFDocumentEditorEnum.ROTATION);

// Get a task id
string taskId = result.TaskId;

// File handling parameter settings
CPDFPageRotationParameter fileParameter = new CPDFPageRotationParameter();
fileParameter.PageOptions = new List<string>() { "1", "2" };
fileParameter.Rotation = "90";

// Upload files
client.UploadFile(new FileInfo("test.pdf"), taskId, fileParameter);

// Execute task
client.ExecuteTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.GetTaskInfo(taskId);

Python

# Create a client
client = CPDFClient(public_key, secret_key)

# Create a task
# Create an example of a PDF rotate task
create_task_result = client.create_task(CPDFDocumentEditorEnum.ROTATION)

# Get a task id
task_id = create_task_result.task_id

# File handling parameter settings
file_parameter = CPDFPageRotationParameter()
file_parameter.page_options = ["1", "2"]
file_parameter.rotation = "90"

# Upload files
client.upload_file('test.pdf', task_id, file_parameter)

# Execute task
client.execute_task(task_id)

# Query TaskInfo
task_info = client.get_task_info(task_id)

Swift

// Create a client
let client: CPDFClient = CPDFClient(publicKey: public_key, secretKey: secret_key)

Task { @MainActor in
    // Create a task
    // Create an example of a PDF rotate task
    let taskModel = await client.createTask(url: CPDFDocumentEditor.ROTATION)
    
    // Get a task id
    let taskId = taskModel?.taskId ?? ""

    // Upload files
    let path = Bundle.main.path(forResource: "test", ofType: "pdf")
    let uploadFileModel = await client.uploadFile(filepath: path ?? "", password: "", params: [
        CPDFFileUploadParameterKey.pageOptions.string():["1"],
        CPDFFileUploadParameterKey.rotation.string() : "90"
    ], taskId: taskId)
    
    // Execute task
    let _ = await client.processFiles(taskId: taskId)
    
    // Query TaskInfo
    let taskInfoModel = await client.getTaskInfo(taskId: taskId)
}

所需参数：

• pageOptions：选择并旋转 page 页面，页码从 1 开始（输入的页码必须大于 0，且不能超过文档的最大页码）。以下是旋转部分页面范围的示例：1,2,5-10。您可以在此处看到所有旋转的页面：第 1、2、5、6、7、8、9、10 页。

• rotation：旋转角度（0、90、180、270）顺时针旋转。

结果：
