Image Preparation

The Image Preparation group allows to perform basic operation before the image is displayed.

  • Background/DarkField image: subtract background or dark field image from a file or from an image source
  • Normalization/BrightField image: apply normalization or bright field image correction from a file or from an image source, i.e. (image - DF) / (BF - DF)
  • Mask image: mask plotted image with respect to a file.
    Convention of zero mask pixels can be set in the configuration,  by default none-zero masks pixel to zero.
  • Mask values above: mask image pixels which have intensity above the given value
  • Transformation: all 8 possible. Whether axes are changing with transformations or not can be set in the configuration.

Background image and mask image can be loaded from the file formats supported by fabio or a NeXus file.
