Change Adjustment Values of the Shape with Node.js via C++

Aspose.Cells provides Shape.getGeometry() property to make changes to the adjustment points with shapes. In the Microsoft Excel UI, adjustments display as yellow diamond nodes. For example:

• Rounded Rectangle has an adjustment to change the arc
• Triangle has an adjustment to change the location of the point
• Trapezoid has an adjustment to change the width of the top
• Arrows have two adjustments to change the shape of the head and tail

This article will explain the use of Shape.getGeometry() property to change the adjustment value of the different shapes.

Change Adjustment Values

The below code sample shows how to change adjustment values of the shape.

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

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Create workbook object from source excel file
const workbook = new AsposeCells.Workbook(path.join(dataDir, "source_shapes.xlsx"));

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

// Access first three shapes of the worksheet
const shape1 = worksheet.getShapes().get(0);
const shape2 = worksheet.getShapes().get(1);
const shape3 = worksheet.getShapes().get(2);

// Change the adjustment values of the shapes
shape1.getGeometry().getShapeAdjustValues().get(0).setValue(0.5);
shape2.getGeometry().getShapeAdjustValues().get(0).setValue(0.8);
shape3.getGeometry().getShapeAdjustValues().get(0).setValue(0.5);

// Save the workbook
workbook.save(path.join(dataDir, "output_out.xlsx"));

How to set or change the RoundedRectangularCallout tip point in excel

The following code example shows how to set or change a rounded rectangle callout tip point position in Excel.

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

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = dataDir + "/"; // Ensure you define filePath

// Create a new workbook
let workbook = new AsposeCells.Workbook();
let sheet = workbook.getWorksheets().get(0);

// Add a RoundedRectangularCallout to the worksheet
let polygonShape = sheet.getShapes().addAutoShape(AsposeCells.AutoShapeType.RoundedRectangularCallout, 0, 0, 0, 0, 0, 0);

polygonShape.setTop(200); // Shape Top properties
polygonShape.setLeft(500); // Shape Left properties
polygonShape.setWidth(200); // Shape Width
polygonShape.setHeight(100); // Shape Height

let shapeGuides = polygonShape.getGeometry().getShapeAdjustValues();
shapeGuides.add("adj1", 1.02167); // The distance between the tip point and the center point
shapeGuides.add("adj2", -0.295);  // The distance between the tip point and the center point
shapeGuides.add("adj3", 0.16667); // Usually the default value

// Save the workbook
workbook.save(path.join(filePath, "res.xlsx"), AsposeCells.SaveFormat.Xlsx);

// Read a new workbook
workbook = new AsposeCells.Workbook(path.join(filePath, "res.xlsx"));
sheet = workbook.getWorksheets().get(0);

// Get a RoundedRectangularCallout from the worksheet
polygonShape = sheet.getShapes().get(0);
shapeGuides = polygonShape.getGeometry().getShapeAdjustValues();
shapeGuides.get(0).setValue(0.7);

// Save the workbook
workbook.save(path.join(filePath, "res-resave.xlsx"), AsposeCells.SaveFormat.Xlsx);
