This tutorial is part of the ID06 memo

Measure sample length from multiple radiographs

In Fit2d

  • Go into the main menu, select Macros / Log Files
  • Select Run Macro and choose the file with the macro (details below)
  • Go out of the macro menu and select Image Processing (General)
  • Select Geometric
  • Select Rebin, with maximum value for x-rebin number, 1 for y-rebin number, 1 for start x, maximum value for end x, and 1 for start y.

Macro for reconstructing the full image

The following file can be saved in a macro, save it as id06Mosaic.mac, for instance.

Parameters to change absolutely:

  • Name and location of the first image: V:\photo\RWD_017\RWD_017_0630.edf
  • Name and location of the last image: V:\photo\RWD_017\RWD_017_0643.edf
  • Name of file to save composite image: V:\photo\RWD_017\RWD_017_0630_0643.tif
  • Vertical translation between images, in pixels: 328, for instance

How to calculate the translation between images

  • If you take 14 images over 4 mm, there is a 4000/13=307.5 microns translation between each image
  • You should divide by the pixel size, 1.0399 microns per pixel,
  • If you have 10 images over 4 mm: translation is 4000/(9*1.0399) = 427.4 pixels

Parameters you can change, if you want

  • Bottom pixel for cropping,
  • Left pixel for cropping,
  • Right pixel for cropping.
