Apply Transformations During Export

The example below demonstrates how to apply geometric transformations during export while applying the Kendo UI Drawing API.

The aim of the example is to produce a PNG image of a section of the page at 4x the original resolution. This is done by applying an uniform 2x scale on the X and Y dimensions. The operation is carried out while the content is still represented in a vector form. No loss of quality occurs.

For more information, refer to the Transformation API article.
