通过C++的Node.js设置页面选项

设置页面选项

Aspose.Cells完全支持页面设置选项。本文介绍了如何使用Aspose.Cells设置页面选项，并显示了用于设置的代码示例：

Aspose.Cells 提供了一个类，Workbook，它代表一个 Microsoft Excel 文件。Workbook 类包含一个 getWorksheets() 集合，允许访问 Excel 文件中的每个工作表。工作表由 Worksheet 类表示。

Worksheet 类提供 PageSetup 属性，用于设置工作表的页面布局选项。实际上，这个 PageSetup 属性是 PageSetup 类的对象，用于设置打印工作表的不同页面布局选项。PageSetup 类提供多种属性，用于设置页面布局，以下将介绍部分属性。

页面方向

可以使用 PageSetup 类的 getOrientation() 属性将页面方向设置为纵向或横向。getOrientation() 属性接受 PageOrientationType 枚举中的预定义值，具体如下：

页面方向类型 描述
Landscape 横向方向
Portrait 纵向方向 
const AsposeCells = require("aspose.cells.node");
const path = require("path");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "PageOrientation_out.xls");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Setting the orientation to Portrait
worksheet.getPageSetup().setOrientation(AsposeCells.PageOrientationType.Portrait);

// Save the Workbook.
workbook.save(filePath);

缩放因子

通过调整 PageSetup.getZoom() 属性的缩放比例，可以缩小或放大工作表的大小。

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Setting the scaling factor to 100
worksheet.getPageSetup().setZoom(100);

// Save the workbook.
workbook.save(path.join(dataDir, "ScalingFactor_out.xls"));

适合页码选项

若要将工作表内容适配到特定的页数，可以使用 PageSetup 类的 getFitToPagesTall() 和 getFitToPagesWide() 属性。这些属性也用于缩放工作表。

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Setting the number of pages to which the length of the worksheet will be spanned
worksheet.getPageSetup().setFitToPagesTall(1);

// Setting the number of pages to which the width of the worksheet will be spanned
worksheet.getPageSetup().setFitToPagesWide(1);

// Save the workbook.
workbook.save(path.join(dataDir, "FitToPagesOptions_out.xls"));

纸张尺寸

使用 PageSetup 类的 getPaperSize() 属性设置打印工作表的纸张大小。getPaperSize() 属性接受 PaperSizeType 枚举中的预定义值，具体如下：

纸张尺寸类型 描述

Custom Represents the custom paper size. 
const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Setting the paper size to A4
worksheet.getPageSetup().setPaperSize(AsposeCells.PaperSizeType.PaperA4);

// Save the Workbook.
workbook.save(path.join(dataDir, "ManagePaperSize_out.xls"));

打印质量

使用 PageSetup 类的 getPrintQuality() 属性设置要打印的工作表的打印质量。打印质量的测量单位为每英寸点数（DPI）。

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Setting the print quality of the worksheet to 180 dpi
worksheet.getPageSetup().setPrintQuality(180);

// Save the Workbook.
workbook.save(path.join(dataDir, "SetPrintQuality_out.xls"));

首页页码

使用 PageSetup 类的 getFirstPageNumber() 属性开始对工作表页面编号。getFirstPageNumber() 属性设置第一张工作表页面的页码，后续页面按升序编号。

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Setting the first page number of the worksheet pages
worksheet.getPageSetup().setFirstPageNumber(2);

// Save the Workbook.
workbook.save(path.join(dataDir, "SetFirstPageNumber_out.xls"));
