!> 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
