ForColormap 0.9.0

Added

• Development:

  • A ROADMAP.md file.
  • A fpm workflow for testing.
  • A GitHub workflow for the CMake build by @jchristopherson.
  • CMake support by @jchristopherson.

• Documentation:

  • A FORD documentation with a CI workflow, generating https://vmagnin.github.io/forcolormap/
  • example/colormaps_list.f90 is creating the colormaps_list/COLORMAPS_LIST_*.md files using the Colormaps_info class.
    • A colormaps_list/ForColormap.pdf manual listing all the available colormaps.
    • A link toward the page ForColormap Collection Categories was added in the README.md to help users choose a colormap.
  • A gallery/ directory with screenshots of simulations using ForColormap.
  • A README.md file in each subdirectory describing the files inside.
  • A logo directory with SVG files by @alozada.

• New modules:

  • The src/colormaps_info.f90 module contains information about colormaps, that can be printed or written in the terminal or to a .md file. Information can be filtered based on 8 parameters and printed in 4 different ways.
    • example/info.f90
    • COLORMAPS_LIST.md: generated by the module.
  • A src/forcolormap_utils.f90 module with the subroutine test_colormap().
  • A colormap_parameters module.
  • A miscellaneous_colormaps module.

• New routines:

  • A colorbar() type-bound procedure to write a PPM file with the colorbar of a colormap.
  • A reverse() method to reverse a colormap.
    • A reverse boolean option was added to the methods set, create, and load to reverse a colormap.
    • An example/demo_reverse.f90 example.
  • A shift() method to apply a circular shift to a colormap (left is +, right is -).
    • example/modify.f90 demonstrates how you can modify a colormap with methods like shift(), in concrete cases.
  • Methods create_lagrange() and create_bezier() in src/colormap_class.f90 to create a colormap from continuous interpolation of control colors.
    • example/create.f90 demonstrates creating a custom colormap using methods like create_lagrange() and create_bezier().
  • An extract() type-bound procedure to the Colormap type to extract colors from a colormap. The extracted number should be within the range [2, levels].
    • example/extract.f90
  • A private check() method in the Colormap class. It checks the validity of the colormap and its parameters, prints warnings, and fixes problems if necessary.
  • Two private functions: scale_real_real and scale_real_int.

• New colormaps:

  • The "magma", "inferno","plasma", "viridis" matplotlib colormaps in a matplotlib_colormaps module.
  • The discrete colormaps of the Scientific Colour Maps collection, thanks to the scripts/gpl_to_lut.f90 program.
  • A black_body colormap (miscellaneous).

• A gtk-fortran example using ForColormap: https://github.com/vmagnin/gtk-fortran-extra/tree/main/reaction_diffusion

Changed

• In example/demo.f90 and example/demo_reverse.f90, the discrete colormap created from an array is now a colormap designed by @alozada resembling the color changes in red cabbage (containing Anthocyanins) with pH.
• Subroutine test_colormap(): the encoding argument is now optional (binary by default).
• The colormap inverted_rainbow was renamed inv_rainbow.
• Renamed get_current() to get_name().
• src/colormap_class.f90: private statement is now the default.
• For writing PPM files, the project ForImage by @gha3mi is now used as a fpm dependency. The related example must now be launched with fpm run --example example1 and the ForColormap demo by fpm run --example demo.
• Code refactoring.

Removed

• The naive "grey" colormap: you should use "grayC" instead.
• The "inverted_grey" colormap which can now be obtained from "grayC" with the reverse=.true. option.
• scripts/cp_lut_files.sh since its functionality is now included in the scripts/gpl_to_lut.f90 program.
