By converting CGM to PPT, Android application developers can easily integrate CGM to PPT conversion feature inside their applications.
How Aspose.Total Helps for CGM to PPT Conversion
Aspose.Total for Android via Java is a comprehensive package of APIs that helps Android application developers to easily integrate CGM to PPT conversion feature inside their applications. It includes two APIs, Aspose.PDF for Android via Java and Aspose.Slides for Android via Java. By using Aspose.PDF for Android via Java, developers can export CGM to PPTX. After that, by using Aspose.Slides for Android via Java, developers can convert PPTX to PPT. Both APIs come under Aspose.Total for Android via Java package. The process of integrating CGM to PPT conversion feature inside Android applications is quite simple and can be done in two steps.
Android API to Export CGM to PPT
- Open CGM file using Document class
- Convert CGM to PPTX by using save method
- Load PPTX document by using Presentation class
- Save the document to PPT format using
save
method and set
Ppt
as SaveFormat
Get Started with Java File Format APIs
You can easily use Aspose.Total for Android via Java directly from Maven and install Aspose.PDF for Android via Java and Aspose.Slides for Android via Java in your applications.
Alternatively, you can get a ZIP file from downloads .
// load CGM file with an instance of Document class
Document document = new Document("template.cgm");
// save CGM as PPTX format
document.save("PptxOutput.pptx", SaveFormat.Pptx);
// instantiate a Presentation object that represents a PPTX file
Presentation presentation = new Presentation("PptxOutput.pptx");
// save the presentation as Ppt format
presentation.save("output.ppt", SaveFormat.Ppt);
Open Password Protected CGM File in Android Apps
While loading CGM file format, your document might be password protected. Aspose.PDF for Android via Java allows you open encrypted documents as well. In order to open the encrypted file, you can initialize new instance of the Document class and pass filename and password as arguments.
// open CGM document
Document doc = new Document("input.cgm", "Your@Password");
// save CGM as PPTX format
document.save("PptxOutput.pptx", SaveFormat.Pptx);
Create Thumbnail Image of PPT File in Android Applications
After converting CGM to PPT, you can also create thumbnail images of your output document. By using rich in feature Aspose.Slides for Android via Java you can generate thumbnail images of the slides by creating and instance of the Presentation class. After that, you can obtain the reference of any desired slide by using its ID or index and get the thumbnail image of the referenced slide on a specified scale.
// instantiate a Presentation object that represents a PPT file
Presentation presentation = new Presentation("output.ppt");
// access the first slide
ISlide sld = pres.getSlides().get_Item(0);
// create a full scale image
BufferedImage image = sld.getThumbnail(1f, 1f);
// save the image to disk in PNG format
ImageIO.write(image, "PNG", new java.io.File("Thumbnail_out.png"));
