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
