How to Compress WMF Files Using Java

Preparing images for publication involves both creative and technical aspects, including file compression. While high-resolution images are crucial for print or outdoor advertising, they might reduce web performance due to their large file size. The appropriate image compression technique varies depending on the purpose and publishing platform. Large files can slow down loading times, particularly on mobile connections, leading to a poor user experience. Users might abandon a site that takes too long to load and seek a faster alternative. Conversely, excessive image compression can result in blurriness and pixelation, degrading the viewing experience. The right choice of compression algorithms and ratios is essential to strike a balance between file size and image quality. In order to compress WMF files, we’ll use Aspose.Imaging for Java API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Java platform. You can download its latest version directly from Maven and install it within your Maven-based project by adding the following configurations to the pom.xml.

Steps to Compress WMF via Java

You need the aspose-imaging-version-jdk16.jar to try the following workflow in your own environment.

  • Load WMF files with Image.load method
  • Compress images;
  • Save compressed image to disc in the supported by Aspose.Imaging format

System Requirements

Aspose.Imaging for Java is supported on all major operating systems. Just make sure that you have the following prerequisites.

  • JDK 1.6 or higher is installed.

  • About Aspose.Imaging for Java API

    Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.

    WMF What is WMF File Format

    Files with WMF extension represent Microsoft Windows Metafile (WMF) for storing vector as well as bitmap-format images data. To be more accurate, WMF belongs to the vector file format category of Graphics file formats that is device independent. Windows Graphical Device Interface (GDI) uses the functions stored in a WMF file to display an image on the screen. A more enhanced version of WMF, known as Enhanced Meta Files (EMF), was published later that makes the format more feature rich. Practically, WMF are similar to SVG.
