用 Node.js 和 C++ 获取工作表页面设置的纸张宽度和高度

可能的使用场景

有时，你需要知道工作表页面设置中的纸张宽度和高度。请使用 PageSetup.getPaperWidth() 和 PageSetup.getPaperHeight() 属性实现此目的。

获取工作表页面设置的纸张宽度和高度

以下示例代码说明如何使用 PageSetup.getPaperWidth() 和 PageSetup.getPaperHeight() 属性。它首先将纸张大小更改为 A2，然后找到纸张的宽度和高度，再依次更改为 A3，A4，Letter，并找到对应的宽度和高度。

示例代码

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, "sample.xlsx");

// Create an instance of Workbook class
const book = new AsposeCells.Workbook();

// Access first worksheet
const sheet = book.getWorksheets().get(0);

// Set paper size to A2 and print paper width and height in inches
sheet.getPageSetup().setPaperSize(AsposeCells.PaperSizeType.PaperA2);
console.log("PaperA2: " + sheet.getPageSetup().getPaperWidth() + "x" + sheet.getPageSetup().getPaperHeight());

// Set paper size to A3 and print paper width and height in inches
sheet.getPageSetup().setPaperSize(AsposeCells.PaperSizeType.PaperA3);
console.log("PaperA3: " + sheet.getPageSetup().getPaperWidth() + "x" + sheet.getPageSetup().getPaperHeight());

// Set paper size to A4 and print paper width and height in inches
sheet.getPageSetup().setPaperSize(AsposeCells.PaperSizeType.PaperA4);
console.log("PaperA4: " + sheet.getPageSetup().getPaperWidth() + "x" + sheet.getPageSetup().getPaperHeight());

// Set paper size to Letter and print paper width and height in inches
sheet.getPageSetup().setPaperSize(AsposeCells.PaperSizeType.PaperLetter);
console.log("PaperLetter: " + sheet.getPageSetup().getPaperWidth() + "x" + sheet.getPageSetup().getPaperHeight());

控制台输出

这是上面示例代码的控制台输出。

PaperA2: 16.54x23.39

PaperA3: 11.69x16.54

PaperA4: 8.27x11.69

PaperLetter: 8.5x11
