These filea sre created:

• when saving the jpg files, there is also a kfb file created for each image
• save a map

Description:

• "KFB files store raw uncompressed (ie huge but high quality) iteration data (the results of the fractal calculations before colouring is applied)." Claude at FF
• "the KFB files are images used as maps to store iteration data. No location, palette, etc" youhn

coloring methods

One can change it :

• Main Menu / Actions/ Set Colors
• keys: Ctrl+C

Available color methods are ( in main.cpp file line 256) :

• Standard = Distance (Linear): Standard iteration band coloring
• Square root: Iterations are squared before colors are appplied
• Cubic root: Cube root is applied before colors
• Logarithm: Logarithm is applied before colors = ColorMethod_Logarithm : "ColorMethod_Logarithm is not DEM at all, it's escape time with non-linear transfer function."
• Stretched: The palette is stretched over min-max iteration values
• Distance: Distance Estimation : "ColorMethod_Distance* have some image processing (looking up iteration values of neighbouring pixels) to generate a pseudo-de colouring. It's not true DEM but looks pretty close sometimes."

Numbers describing methods ( variable m_nColorMethod) are changing between versions

Code:

• file fraktal_sft.cpp
• variable m_nColorMethod
• functions:
  • CFraktalSFT::SetColorMethod
  • void CFraktalSFT::SetColor
  • CFraktalSFT::OpenFile
  • CFraktalSFT::SaveFile
