Package net.sf.ij.jaiio Description

Image I/O library implements core functionality of ij-plugins Image I/O bundle. The library adds to ImageJ support for additional image file formats and their variants. Most important additions include:

• Extended TIFF support
• • Reading of compressed and tiled TIFF files
  • Reading of TIFF images with 1 bit, 8 bit, 16 bit, 32 bit, and float pixel formats from compressed and tiled files. Images are converted to closest corresponding ImageProcessor representation (). Note that related set of JIMI plugins converts all images to 8 bit images (ByteProcessor) regardless of their actual pixel formats and does not support tiled images.
  • Saving as compressed TIFF; supports Packbit, JPEG, and ZIP compression. Saving with LZW compression is not supported for the usual reason of the patent on the algorithm.
  • Saving of binary images in 1 bit compressed TIFF format. Compared to saving as uncompressed 8bit images can get 1:100 or higher compression ratios.
• Correct reading of 16bit PNG images (without conversion to 8 bit)
• Saving in PNG format, includes support for compression.
• Saving in PNM format.

Image I/O plugins can read/write image calibration information from TIFF files. Standard TIFF image calibration tags are supported (X_RESOLUTION, Y_RESOLUTION, RESOLUTION_UNIT).

Additionally Image I/O can read images in BMP, FlashPiX, GIF, JPEG, PNG, and PNM formats; and save images in BMP, and JPEG formats.

Image I/O makes use of Java Advance Imaging (JAI) codecs released by SUN as uncommitted source code for JAI 1.1.1 codecs . The plugin bundle is completely self contained. All used codec classes are included in the bundle and there is no need to install JAI itself to use the bundle.
