Public API Changes in Aspose.Diagram 16.12.0

This document describes changes to the Aspose.Diagram API from version 16.11.0 to 16.12.0, that may be of interest to module/application developers. It includes not only new and updated public methods, but also a description of any changes in the behaviour behind the scenes in Aspose.Diagram.

Modify Properties of a Gradient

Developers can retrieve a gradient stop and then modify its properties. We have added GradientFill and GradientStop classes for this purposes. Please check the code example:

Java

 // load a Visio drawing

Diagram diagram = new Diagram("C:\\temp\\MyVisio.vsdx");

// get page by name

Page page = diagram.getPages().getPage("Page-1");

// get shape by ID

Shape shape = page.getShapes().getShape(1);

// get the gradient fill properties

GradientFill gradientfill = shape.getFill().getGradientFill();

// get the gradient stops

GradientStopCollection stops = gradientfill.getGradientStops();

// get the gradient stop by index

GradientStop stop = stops.get(0);

// set gradient stop properties

stop.getColor().getUfe().setF("");

stop.getPosition().setValue(0.5);

gradientfill.getGradientDir().setValue(GradientFillDir.RECTANGLE_FROM_BOTTOM_RIGHT);

gradientfill.getGradientAngle().setValue(0.7853981633974501);

// save the Visio drawing

diagram.save("C:\\temp\\Output.pdf", SaveFileFormat.PDF);
