This is a modified version of a submission for a Twitter image encoding challenge found here: https://stackoverflow.com/a/929360

Requirements

• TCLAP (https://github.com/eile/tclap)
• Magic++ (libgraphicsmagick1-dev)

Install

• Clone the repo.
  1. git clone https://github.com/NeuroWinter/NanoBrunch.git
  2. Change directory to the project cd NanoBrunch
• Make the project.
  1. cmake CMakeLists.txt
• If there are problems try and find what dependencies are missing.

Running the project

1. Encode the image.

• ./nanobrunch -e -i {Your input image} -o {OutputFilename}

2. Decode the image.

• ./nanobrunch -d -i {OutputFilename from step one} -o {FinalImageName}.png

Flags:

You can only use one of these at a time.

• -e Encode the input image.
• -d Decode the input image.

Parameters:

• -i Path and filename of the input image.
• -o Path and filename of the output image.
• -x Steps in X.
  • I am not too sure what this does at this point.
• -y Steps in Y.
  • I am not too sure what this does at this point.
• -r Steps in red.
  • I am not too sure what this does at this point.
• -g Steps in green.
  • I am not too sure what this does at this point.
• -b Steps in blue.
  • I am not too sure what this does at this point.
• -k Blocks in X.
  • if you increase this number there will be more sections of the image on the X axis that are split up into fractal representations of that block.
• -l Blocks in Y.
  • if you increase this number there will be more sections of the image on the Y axis that are split up into fractal representations of that block.
• -a Weight for colour A.
  • A higher weight here will make the final image more blocky.
• -c Weight for colour B.
  • A higher weight here will make the final image more 'fractaly'.
• -t Iterations for decoding.
  • This doesn't do too much.
• -z Zoom level.
  • This is a great setting to play with. Both encoding and decoding uses this to find fractals.
• -s Output resolution.
  • Force the output resolution to a set size.
• --clr Colour space.
  • Supported Colour types are: CMY, CYMK, GRAY, HCL, HCLp, HSB, HSI, HSL, HSV, HWB, HWB, LAB, LCH, LCHAB, LCHUV, LOG, LMS, LUV, OHTA, RGB, SCRGB, SRGB, XYY, XYZ, YCB, YCC, YDB, YIQ, YPB, YUV.
