限制和 API 差异

公共 API 差异

以下列表（带有示例代码段）显示了 Aspose.Slides for Java 和通过 Java 的 Aspose.Slides for Node.js APIs 之间的一些差异。

导入库（软件包比较）

Aspose.Slides for Java

import com.aspose.slides.*;

Aspose.Slides for Node.js via Java

var aspose = aspose || {};
aspose.slides = require("aspose.slides.via.java");

实例化新的演示文稿

Aspose.Slides for Java

Presentation pres = new Presentation();

Aspose.Slides for Node.js via Java

var pres = new aspose.slides.Presentation();

流文件和常量

Aspose.Slides for Java

InputStream inputstream = new FileInputStream("Pres1.pptx");
Presentation pres = new Presentation(inputstream);
pres.save("result.pptx", SaveFormat.Pptx);

Aspose.Slides for Node.js via Java

var aspose = aspose || {};

aspose.slides = require("aspose.slides.via.java");

var fs = require("fs");
var readStream = fs.createReadStream("presentation.pptx");
aspose.slides.Presentation.createPresentationFromStream(readStream, function(err, pres) {
   if (err) {
      console.log("打开演示文稿错误");
      return;
   }
   pres.save("result.pptx", aspose.slides.SaveFormat.Pptx));
   console.log('已保存到文件');
});

与 Aspose.Slides for Java API 相比，通过 Java API 的 Aspose.Slides for Node.js 的其他限制

1. 不支持从 Array、ArrayList、ResultSet 等导入/导出数据。
2. 不支持打印。
