  • HarFA 5.0 full version is sciware. We would like to publish experimental results obtained by HarFA or any scientific information concerning Box Counting or fractal analysis of images in the e-journal form on our webpages. So the term 'sciware' means that full version of HarFA 5.0 can be obtained after sending and accepting your contribution to this e-journal. If you prefer another way of HarFA purchasing please write to us.

    Information for Contributors
    Send manuscript together with filled questionary to the authors of HarFA. We require 5000 chars (including spaces) or two pages A4 including graphics at least. Further information for contributors are included in the questionary. Example of contribution can be downloaded here.

    We require 5000 chars (including spaces) or two pages A4 including graphics at least. We prefer Microsoft Word documents (*.doc) or Rich Text Format (*.rtf) files. In exceptional cases Post Script Files (*.ps) or Encapsulted Post Script Files (*.eps) are acceptable too. All manuscripts submitted are subject to peer review. Editors reserve right to perform layout changes, which are necessary to keep contributions in the uniform format. Author's laws remain untouched by publishing contribution in our e-journal. Author of contribution can further publish it anywhere he wants. Manuscript Preparation Length: at least 5000 chars (including spaces) or two pages A4 including graphics Layout demands: margins 25mm above and below, 25mm on the left and right Text: 12pt Times New Roman font on A4, single spacing

    Version 4.9 released on October 2002

  • JPEG support ! Since built 4.9.3. But be careful - JPEG graphic format is not advisable for analysis because of compression. Compression patterns can distort results of analysis.
  • Data export ! Since built 4.9.3. You can export all chart data in the following file formats: data (XLS (excel), HTML, XML, TEXT), picture (metafile, bitmap), and native (TeeChart native).
  • Resizable FFT area (32, 64, 128, 256, 512, 1024, 2048 pixels)
  • Range thresholding - enables thresholding between two border values, Min and Max
  • Redesigned GUI
  • Newer version of TFastDIB unit (by Gordon Alex Cowie) implemented
  • Version 4.0 released on October 2001

  • much more faster (some operations cca 10 000x).
  • the precision of method has been significantly increased by the random mesh placement operation (see Literature --> The Box-Counting: Critical Study).
  • classical Box-Counting (as reffered in literature (B+BW squares)) has been implemented.
  • slope analysis improved by Single Slope Analysis and OverAll Slope Analysis tool - a kind of multifractal analysis.
  • enables loading and saving TIFF files.
  • enables loading and viewing images larger then 640x480 pixels.
  • range analysis has been improved too (spectra loading).
  • better chart manipulations (pop-up menus to customize the amount of displayed information)
