Procedures

ProcedureLocationProcedure TypeDescription
bezier forcolormap Function

Create colormap from continuous Bezier interpolation of control colors
check forcolormap Subroutine

Check validity of the colormap and fix it if necessary
compute_RGB forcolormap Subroutine

Most of the time you will just give z to obtain RGB values:
create forcolormap Subroutine

You can create a custom colormap from a "map" array.
create_bezier forcolormap Subroutine

You can create a custom colormap using Bezier interpolation:
create_lagrange forcolormap Subroutine

You can create a custom colormap using Lagrange interpolation:
cubehelix_colormap miscellaneous_colormaps Subroutine

This subroutine is based on the public domain FORTRAN 77 subroutine published by D.A. Green: Green, D. A., 2011, Bulletin of the Astronomical Society of India, Vol.39, p.289 For more information on the parameters of cubehelix, see his page: https://www.mrao.cam.ac.uk/~dag/CUBEHELIX/
deallocate_Colormaps_info forcolormap_info Subroutine
deallocate_table forcolormap_info Subroutine
error colormap_class.f90 Subroutine
extract forcolormap Subroutine

Extracts colors from the colormap based on specified number of levels (nl)
factorial forcolormap Function

Factorial function used for Bezier interpolation
finalize forcolormap Subroutine

A finalizer procedure for memory cleanup:
findColumnIntersections forcolormap_info Function

Finds intersections between elements of the first column and other columns in the input array.
fire_colormap miscellaneous_colormaps Subroutine
get_levels forcolormap Function
get_levels forcolormap_info Function
get_name forcolormap Function
get_name forcolormap_info Function
get_ncolormaps forcolormap_info Function
get_RGB forcolormap Subroutine

But you can also obtain RGB by giving directly a level number:
get_zmax forcolormap Function
get_zmin forcolormap Function
inv_rainbow_colormap miscellaneous_colormaps Subroutine
lagrange forcolormap Function

Create colormap from Lagrange interpolation of control colors
lagrange_poly forcolormap Function
load forcolormap Subroutine

Load a .txt colormap with RGB integers separated by spaces on each line. Remark: if no path is indicated in filename, the .txt must be present at the root of the fpm project of the user.
print forcolormap Subroutine

Useful for testing and debugging:
rainbow_colormap miscellaneous_colormaps Subroutine
reverse forcolormap Subroutine

Reverse the colormap
scale_real_int forcolormap Function

Scale the input real array to the integer RGB range [a, b]
scale_real_real forcolormap Function

Normalize the input real array to the range [0, 1]
set forcolormap Subroutine
set_all forcolormap_info Subroutine

Set information for all colormaps.
set_info forcolormap_info Subroutine

Set information about the colormap
shift forcolormap Subroutine

Apply a circular shift to the colormap (left is +, right is -)
write forcolormap_info Subroutine

Filter the array of colormaps based on the given criteria and write information about the filtered colormaps
write_info forcolormap_info Subroutine

Print information about the colormap
write_ppm_colorbar forcolormap Subroutine
zebra_colormap miscellaneous_colormaps Subroutine
