Convert CGM to PNG in Java & J2SE Applications

Convert Password Protected CGM to PNG

Accurately load and convert documents that are protected with a password within your Java based applications. The file format conversion API also supports rendering remote documents from different sources including S3, Blob, FTP, Stream, URL or a local disk.

Create new instance of Converter class and pass source document path
Instantiate the proper ConvertOptions class e.g. (PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions etc.)
Call convert method of Converter class instance and pass filename for the converted document

Source Document Information Extraction

The documents information extraction feature not only allows getting the basic information about the source document file but it also supports extracting some valuable file-format specific information such as project start and end dates of a Microsoft Project file, any printing restrictions on a PDF document, list of folders enclosed in an Outlook data file etc.

Convert popular document file formats on different operating systems such as Windows, Linux or macOS while using development environments such as NetBeans, IntelliJ IDEA and Eclipse.

Convert Specific Word Pages to PDF in Java

Java document conversion API allows you to choose selected pages from the source document and accurately convert to the supported document format. The code example below shows how to convert the 1st and 4th pages of a Word document to the resultant PDF file.

Create a new instance of Converter class and load input (Word) document
Instantiate the proper ConvertOptions class e.g. (PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions etc)
Set setPages property of the ConvertOptions instance and mention specific page number to be converted
Call convert method of Converter class instance and pass filename (PDF) for the converted document

Caching Converted Document Results

In some cases, the converted document size is bigger and it takes time to be converted. The document conversion library offers the caching feature to efficiently manage such situations and speed up the repetitive conversion process. Enable the ICache interface to work with custom cache implementation using the extension point and control the cache conversion, as you prefer.

The conversion result is saved to the local drive by default but any type of cache storage can be supported by implementing the appropriate interfaces such as Amazon S3, Dropbox, Google Drive, Windows Azure, Reddis or any other.

What is CGM file format?

CGM (Computer Graphics Metafile) is a vector-based graphics file format that was developed by the International Standards Organization (ISO) in 1982. It is used for storing and exchanging 2D vector graphics, text, and bitmaps. CGM files are widely used in many industries such as engineering, mechanics, architecture and 3D modeling. CGM files typically have the file extension .cgm or .cg and can be opened and edited with a number of software programs such as Adobe Illustrator and CorelDraw. CGM files are considered to be superior to other standard graphics formats such as JPG, GIF and BMP because they are more efficient, allowing for better image quality and smaller file sizes. Additionally, CGM files can be used across different computer platforms and operate properly on multiple operating systems such as Windows and Mac OS. Overall, CGM files are a reliable and efficient way of storing and exchanging vector graphics, text, and bitmaps. They are widely used all over the world, and can be found in many different industries.

What is PNG file format?

PNG, short for Portable Network Graphics, stands as a raster graphics file format renowned for its lossless data compression and its suitability for displaying images on the web. It has gained significant popularity among graphic designers and photographers who seek to store and showcase high-quality images. One of the distinctive features of PNG files is their support for transparency, setting them apart from JPEG files that cannot contain transparent areas.

The PNG file format provides several advantages that contribute to its appeal. Firstly, it supports 16-bit color, enabling the preservation of more accurate colors during image editing processes. This feature proves valuable for professionals working with intricate color details. Additionally, PNG supports gamma correction, ensuring that images display correctly across various systems. This capability helps to maintain consistent visual quality across different devices and platforms.

Furthermore, PNG employs lossless data compression, allowing for efficient reduction of file size without compromising image quality. This compression technique facilitates faster download times and improved web page loading performance. The smaller file sizes make PNG files more convenient to store, transfer, and share, making them an ideal choice for web-based applications.

PNG files have gained widespread support across major web browsers and operating systems, further contributing to their popularity. This compatibility ensures that PNG images can be reliably viewed and displayed across different platforms and devices, enhancing accessibility and user experience. Moreover, PNG is widely supported by various image editing and drawing software programs, including industry-standard applications like Adobe Photoshop. This compatibility allows professionals to work seamlessly with PNG files, leveraging advanced editing capabilities to achieve their desired outcomes.
