@progress/kendo-drawing

What is @progress/kendo-drawing?

@progress/kendo-drawing is a powerful library for creating and manipulating vector graphics in web applications. It provides a rich API for drawing shapes, paths, and text, as well as for applying transformations and styles. The library is part of the Kendo UI suite and is designed to work seamlessly with other Kendo UI components.

What are @progress/kendo-drawing's main functionalities?

Drawing Shapes

This feature allows you to draw basic shapes like circles, rectangles, and ellipses. The code sample demonstrates how to create a circle with a specific stroke and fill color.

const draw = require('@progress/kendo-drawing');
const surface = draw.Surface.create(document.getElementById('surface'));
const circle = new draw.Circle(new draw.geometry.Circle([100, 100], 50), {
  stroke: {
    color: '#000',
    width: 2
  },
  fill: {
    color: '#ff0000'
  }
});
surface.draw(circle);

Drawing Paths

This feature allows you to draw complex paths by defining a series of points and lines. The code sample demonstrates how to create a path with multiple line segments.

const draw = require('@progress/kendo-drawing');
const surface = draw.Surface.create(document.getElementById('surface'));
const path = new draw.Path({
  stroke: {
    color: '#000',
    width: 2
  }
});
path.moveTo(10, 10).lineTo(100, 100).lineTo(200, 50);
surface.draw(path);

Applying Transformations

This feature allows you to apply transformations such as rotation, scaling, and translation to shapes. The code sample demonstrates how to rotate a rectangle around a specific point.

const draw = require('@progress/kendo-drawing');
const surface = draw.Surface.create(document.getElementById('surface'));
const rect = new draw.Rect(new draw.geometry.Rect([50, 50], [100, 100]), {
  stroke: {
    color: '#000',
    width: 2
  },
  fill: {
    color: '#00ff00'
  }
});
rect.transform(draw.transform().rotate(45, [100, 100]));
surface.draw(rect);

Styling Elements

This feature allows you to style elements such as text and shapes with various properties like font, color, and stroke. The code sample demonstrates how to style a text element.

const draw = require('@progress/kendo-drawing');
const surface = draw.Surface.create(document.getElementById('surface'));
const text = new draw.Text('Hello, World!', [50, 50], {
  font: 'bold 20px Arial',
  fill: {
    color: '#0000ff'
  }
});
surface.draw(text);
