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.
How Aspose.Total Helps for CGM to OTP Conversion
Aspose.Total for Android via Java is a comprehensive suite of APIs that enables developers to easily integrate CGM to OTP conversion feature into their Android applications. The suite includes two APIs, Aspose.PDF for Android via Java and Aspose.Slides for Android via Java, which can be used to export CGM to PPTX and then convert PPTX to OTP, respectively.
The Aspose.PDF for Android via Java API provides a set of classes and methods that allow developers to easily create, read, modify, and convert PDF documents. It also supports the export of CGM to PPTX format. The Aspose.Slides for Android via Java API provides a set of classes and methods that allow developers to create, read, modify, and convert presentations. It also supports the conversion of PPTX to OTP format.
By using these two APIs, developers can easily integrate CGM to OTP conversion feature into their Android applications. The APIs are easy to use and provide a wide range of features that make it easy to create, read, modify, and convert documents and presentations. Furthermore, the APIs are highly reliable and provide excellent performance.
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 via Java
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"));

What is CGM File Format?
A Computer Graphics Metafile (CGM) is a file format for 2D vector graphics, raster graphics, and text, and is defined by ISO/IEC 8632. CGM files may contain 2D vector graphics, raster graphics, and text. All aspects of the graphics can be stored, including color palettes, line widths, fonts, and text size and location. CGM files usually have a .cgm filename extension, but they may also use .cgi, .cgmz, or .cgz.CGM is a platform-independent file format, meaning that it can be used on any type of computer, regardless of the operating system. CGM files are often used for vector graphics because they can be scaled without losing quality. CGM files are also used for technical drawings, such as engineering diagrams, because they can be accurately printed at any size.CGM files can be created by a wide variety of software programs, including vector graphics editors, CAD programs, and word processors. Many programs that can export to CGM format also support importing CGM files.
What is OTP File Format?
The OpenDocument Standard Format (ODF) serves as an XML-based file format for representing various electronic documents, including spreadsheets, charts, presentations, and word processing documents. The format is standardized by the Organization for the Advancement of Structured Information Standards (OASIS) and was initially adopted by ISO/IEC JTC1 SC34 in 2005. One of the key advantages of ODF is that it is an open format, meaning it is not restricted by copyright or patent limitations.
ODF is built upon the XML schema derived from the OpenOffice.org office suite and employs the Zip compression algorithm. Its design objective is to be platform-independent, enabling support across a wide range of applications and operating systems.
The ODF specification defines three main document types: text documents, spreadsheets, and presentations. Each document type corresponds to a specific XML schema. These schemas are designed to be extensible, allowing for the addition of application-specific features.
ODF documents have the capability to be encrypted and signed using the XML Encryption and XML Signature standards. This provides security and integrity options for sensitive or important documents.
Numerous office applications support the OpenDocument Format, including Apache OpenOffice, LibreOffice, IBM Lotus Symphony, and even Microsoft Office. This broad support ensures compatibility and facilitates the exchange and collaboration of documents across different software platforms.
