Scalebar - afast/map_print GitHub Wiki

Place a scale bar on your map to provide a general idea of distances.

Currently we only support a "bar" scale bar with the following options:

• unit Can be meters, km, miles or feet
• position: {x: 40, y: 40} Where on the png/pdf to place the scalebar
• size: {width: 200, height: 40} Size in pixels for the scale bar.
• padding: {top: 0, right: 0, bottom: 0, left: 0} this allows to separate the border from the scale bar itself
• bar_height how tall to draw the bar
• background_color Color to use for the scale bar background, ImageMagick is used to anything it accepts including 'transparent', or hex.
• background_opacity if you want the background color to include some transparency.
• text_style styling options:
  • fill_color background color
  • color the text color.
  • font the font to use, make sure it is installed on your system.
  • pointsize the size of the text.
  • gravity Where on the box to align the text.
