Data in Non-Primitive Shape with Node.js via C++

Accessing Data of Non-Primitive Shape

Sometimes, you need to access data from a shape that is not built-in. Built-in shapes are called primitive shapes; ones that aren’t are called non-primitive. For example, you can define your own shapes using different curve connected lines.

A Non-Primitive Shape

In Aspose.Cells for Node.js via C++, non-primitive shapes are assigned the type AutoShapeType.NotPrimitive. You can check their type using the Shape.getAutoShapeType() property.

Access the shape data using the Shape.getPaths() property. It returns all the connected paths that comprise the non-primitive shape. These paths are of the type ShapePath that holds a list of all the segments which in turn contain the points in each segment.

Shows an example of a non-primitive shape

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, "NonPrimitiveShape.xlsx");
// Loads the workbook which contains hidden external links
const workbook = new AsposeCells.Workbook(filePath);

const worksheet = workbook.getWorksheets().get(0);

// Accessing the user defined shape
const shape = worksheet.getShapes().get(0);

if (shape.getAutoShapeType() === AsposeCells.AutoShapeType.NotPrimitive) 
{
// Access shape's data
const shapePathCollection = shape.getPaths();

// Access information of individual path
for (let i = 0; i < shapePathCollection.getCount(); i++) 
{
const shapePath = shapePathCollection.get(i);
// Access path segment list
const pathSegments = shapePath.getPathSegementList();

// Access individual path segment
for (let j = 0; j < pathSegments.getCount(); j++)
{
const pathSegment = pathSegments.get(j);
// Gets the points in path segment
const segmentPoints = pathSegment.getPoints();

for (let k = 0; k < segmentPoints.getCount(); k++) 
{
const pathPoint = segmentPoints.get(k);
console.log("X: " + pathPoint.getX() + ", Y: " + pathPoint.getY());
}
}
}
