IIPImage is an advanced high-performance feature-rich image server system for web-based streamed viewing and zooming of ultra high-resolution images. It is designed to be fast and bandwidth-efficient with low processor and memory requirements. The system can comfortably handle gigapixel size images as well as advanced image features such as 8, 16 and 32 bits per channel, CIELAB colorimetric images and scientific imagery such as multispectral images and digital elevation maps.

Streaming is tile-based, making it possible to view, navigate and zoom in real-time around gigapixel size images that would be impossible to download and manipulate on the local machine. It also makes the system very scalable as the number of image tile downloads will remain the same regardless of the size of the source image.

Source images can be in either TIFF or JPEG2000 format. Whole images or regions within images can also be rapidly and dynamically resized and exported by the server from a single source image without the need to store multiple files in various sizes.

  • Fast lightweight Fast CGI server module that can be embedded in most web servers (Apache, IIS, Lighttpd, Nginx etc) or used standalone
  • Several clients available – HTML5, flash, java applet etc
  • Instant dynamic generation of JPEG overviews or details at any resolution
  • Allows easy viewing of extremely large images (terabyte size) with no significant memory requirements
  • One single image source file, not thousands of small separate files
  • Standard TIFF-based image format that can be created, read and manipulated by most image processing tools (Photoshop, ImageMagick, GIMP, VIPS etc)
  • JPEG2000 support
  • 8, 16 or 32 bits per channel image handling
  • Greyscale, sRGB and CIE L*a*b* colour spaces
  • Multispectral imaging
  • Image blending
  • Multi-protocol with support for the IIP, IIIF, Zoomify and DeepZoom protocols
  • Dynamic watermarking
  • Support for Memcached, a distributed memory object caching system
  • Secure image distribution: only JPEG-compressed views of the image are sent to the client. The full-resolution image does not need to be accessible
  • Panoramic 3D object image sequences
