!> This example demonstrates creating a custom colormap using methods like
!> create_lagrange() and create_bezier().
program create
    use forcolormap, only: Colormap, wp
    implicit none

    type(Colormap) :: custom_cmap
    integer :: colors(3,3)

    ! Define control colors for the colormap.
    colors(1,:) = [255, 0, 0] ! Red
    colors(2,:) = [0, 255, 0] ! Green
    colors(3,:) = [0, 0, 255] ! Blue

    ! Create a custom colormap using Lagrange interpolation.
    call custom_cmap%create_lagrange('custom_lagrange',  0.0_wp, 2.0_wp, colors, 1024)
    call custom_cmap%colorbar('custom_colorbar_lagrange')
    print *, "See the custom_colorbar_lagrange.ppm colorbar"

    ! Create a custom colormap using Bezier interpolation.
    call custom_cmap%create_bezier('custom_bezier',  0.0_wp, 2.0_wp, colors, 1024)
    call custom_cmap%colorbar('custom_colorbar_bezier')
    print *, "See the custom_colorbar_bezier.ppm colorbar"

end program create
