Aspose.Diagram 用于 Node.js 示例

Aspose.Diagram for Node.js is easy to use and lets you work with Visio diagrams without any understanding of underlying file format. You can create Visio VSDX files from scratch using simple lines of code. You can also convert VSDX files to PNG with just a couple of lines of code. In this article, we list some basic examples for working with Visio VSDX files using Aspose.Diagram for Node.js API.

使用 Node.js 从头开始创建 Visio VSDX

 var aspose = aspose || {};

aspose.diagram = require("aspose.diagram");

var diagram = new aspose.diagram.Diagram();

diagram.save("output.vsdx", aspose.diagram.SaveFileFormat.VSDX);

Export Page of Visio VSDX File to PNG Format

 var aspose = aspose || {};

aspose.diagram = require("aspose.diagram");

diagram = new aspose.diagram.Diagram("template.vsdx");

// Save diagram as PNG

options = new aspose.diagram.ImageSaveOptions(aspose.diagram.SaveFileFormat.PNG);

// Save one page only, by page index

options.setPageIndex(0);

// Save resultant Image file

diagram.save("output.png", options);
