IIPImage]

IIPImage is an advanced high-performance feature-rich imaging 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 both 8 and 16 bit depths, CIELAB colorimetric images and scientific imagery such as multispectral images.

Examples

Pulling specific width images from pyramids

  • iipimage-server-url?FIF=/Full/Pyramid/Path&SDS=0,90&CNT=1.0&WID=PIXELWIDTH&QLT=75&CVT=jpeg
  • Please note in the examples given below the &.jpg suffix at the end of some of the address within the MediaWiki syntax is not needed by IIPImage, it is just required to ensure that MediaWiki treats it like a normal external image.
  • Also the maximum image width or height that can be used here can be limited on the server using the MAX_CVT server variable, see website for more details.
