mappyfile-colors 0.3.0

Installation

pip install mappyfile-colors

Note installing the mappyfile-colors plugin will automatically install the following dependencies:

• mappyfile

• webcolors

Online Demo

• Go to the online mappyfile demo at http://mappyfile.geographika.net/

• Select the “Rainbow colors” map

• Open “Settings”, the mappyfile-colors Plugin Settings section allows conversion to RGB and HEX, and to include color names as comments in the Mapfile output

• Click the Format button

Usage

To use the colors plugin, import it to a script, and then pass in a custom ColorsTransformer. Two additional parameters can also be passed to the mappyfile.loads function:

• include_color_names - set to True to add color names as comments (default is False)

• conversion_type - a parameter to convert colors within a Mapfile, either import ConversionType or use an integer value to set the conversion:

  NO_CONVERSION = 0
  TO_RGB = 1
  TO_HEX = 2

A sample script to convert RGB to HEX colors, and include the color names is shown below.

from mappyfile.plugins import mappyfile_colors
from mappyfile_colors import ColorsTransformer, ConversionType

s = """
CLASS
    STYLE
        COLOR 184 134 11
        OUTLINECOLOR 0 0 255
        WIDTH 3
    END
END
"""

d = mappyfile.loads(s, include_color_names=True, include_comments=True, transformerClass=ColorsTransformer, conversion_type=ConversionType.TO_HEX)
print(mappyfile.dumps(d))

This will output the following:

CLASS
    STYLE
        COLOR "#b8860b" # darkgoldenrod
        OUTLINECOLOR "#0000ff" # blue
        WIDTH 3
    END
END
