フォント設定をNode.js経由のC++で

フォント設定の構成

Aspose.Cellsは、Microsoft Excelファイルを表すクラスWorkbookを提供しています。Workbookクラスは、Excelファイル内の各ワークシートへアクセスできるWorksheetsコレクションを含みます。ワークシートはWorksheetクラスによって表されます。WorksheetクラスはCellsコレクションを提供し、その中の各アイテムはCellクラスのオブジェクトを表します。

Aspose.Cellsは、セルの書式設定スタイルを取得および設定に使用されるCellクラスのgetStyleおよびsetStyleメソッドを提供します。Styleクラスはフォント設定を構成するためのプロパティを提供します。

フォント名の設定

開発者は、FontオブジェクトのsetNameメソッドを使用して、セル内のテキストに任意のフォントを適用できます。

const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Create directory if it is not already present.
const fs = require("fs");
if (!fs.existsSync(dataDir)) {
fs.mkdirSync(dataDir);
}
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Adding a new worksheet to the Excel object
const i = workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(i);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello Aspose!");
// Obtaining the style of the cell
const style = cell.getStyle();
// Setting the font name to "Times New Roman"
style.getFont().setName("Times New Roman");
// Applying the style to the cell
cell.setStyle(style);
// Saving the Excel file
workbook.save(path.join(dataDir, "book1.out.xls"), AsposeCells.SaveFormat.Excel97To2003);

太字にフォントスタイルを設定する

開発者は、FontオブジェクトのsetIsBoldメソッドをtrueに設定して、テキストを太字にできます。

const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "sample.xlsx");
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Adding a new worksheet to the Excel object
const i = workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(i);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello Aspose!");
// Obtaining the style of the cell
const style = cell.getStyle();
// Setting the font weight to bold
style.getFont().setIsBold(true);
// Applying the style to the cell
cell.setStyle(style);
// Saving the Excel file
workbook.save("out.xlsx");

フォントサイズの設定

FontオブジェクトのsetSizeメソッドを使用してフォントサイズを設定します。

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");
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Adding a new worksheet to the Excel object
const i = workbook.getWorksheets().getCount();
workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(i);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello Aspose!");
// Obtaining the style of the cell
const style = cell.getStyle();
// Setting the font size to 14
style.getFont().setSize(14);
// Applying the style to the cell
cell.setStyle(style);
// Saving the Excel file
workbook.save("out.xlsx");

フォントの色の設定

FontオブジェクトのsetColorメソッドを使用してフォントの色を設定します。Color列挙体(Node.jsの一部)から任意の色を選択し、setColorメソッドに割り当てます。

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");
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Adding a new worksheet to the Excel object
const i = workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(i);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello Aspose!");
// Obtaining the style of the cell
const style = cell.getStyle();
// Setting the font color to blue
style.getFont().setColor(AsposeCells.Color.Blue);
// Applying the style to the cell
cell.setStyle(style);
// Saving the Excel file
workbook.save("out.xlsx");

フォントの下線タイプの設定

FontオブジェクトのsetUnderlineメソッドを使用してテキストに下線を引きます。Aspose.Cellsは、FontUnderlineType列挙体にさまざまな事前定義されたフォント下線タイプを提供します。

フォントの下線の種類 説明
Accounting 単一のアカウンティング下線
Double ダブル下線
DoubleAccounting ダブルアカウンティング下線
None 下線なし
Single 単一の下線
const AsposeCells = require("aspose.cells.node");
const path = require("path");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const outputPath = path.join(dataDir, "out.xlsx");
// Create directory if it is not already present.
if (!require("fs").existsSync(dataDir)){
require("fs").mkdirSync(dataDir);
}
// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();
// Adding a new worksheet to the Excel object
const i = workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(i);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello Aspose!");
// Obtaining the style of the cell
const style = cell.getStyle();
// Setting the font to be underlined
style.getFont().setUnderline(AsposeCells.FontUnderlineType.Single);
// Applying the style to the cell
cell.setStyle(style);
// Saving the Excel file
workbook.save(outputPath);

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();
// Adding a new worksheet to the Excel object
const i = workbook.getWorksheets().add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
const worksheet = workbook.getWorksheets().get(i);
// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");
// Adding some value to the "A1" cell
cell.putValue("Hello Aspose!");
// Obtaining the style of the cell
const style = cell.getStyle();
// Setting the strike out effect on the font
style.getFont().setIsStrikeout(true);
// Applying the style to the cell
cell.setStyle(style);
// Saving the Excel file
workbook.save(path.join(dataDir, "out.xlsx"));

下付き文字の効果の設定
