Convert CGM to OTP on Android via Java
Transform CGM to OTP within your Android Applications without using Microsoft® PowerPoint or Adobe® Acrobat Reader
Why to Convert
The CGM (Computer Graphics Metafile) format is a vector-based graphics format that is used to store and exchange graphics data. It is widely used in the engineering and technical fields, and is also used in the printing industry. However, the OTP (OpenType Font) format is a more modern and widely used format for storing and exchanging text and graphics data. Therefore, it is often necessary to convert CGM to OTP in order to make the data more accessible and easier to use.

Android API to Export CGM to OTP
- 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 OTP format using
save
method and set
Otpas 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 Otp format
presentation.save("output.otp", SaveFormat.Otp);
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 OTP File in Android Applications
After converting CGM to OTP, 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 OTP file
Presentation presentation = new Presentation("output.otp");
// 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"));
