Print Control for Mapbox GL

PDF and PNG exports for the Port of Portland

Originally created as a Mapbox (MB) Control, it's now implemented as a link/button feature.

Dependencies:

• Canvas To Blob
• JSPDF
• PDF-JS
• FileSaver
• HTML2Canvas
• Mapbox GL

How To:

• Users pass both the map and a set of options to PrintControl.prototype.initialize(map, printOptions)

    var printOptions = { disclaimer: 'This is my map disclaimer', northArrow: '../path/to/img.svg', defaultTitle: 'My Map' }
  

• Add a bootstrap modal - example found in index.html
• Ensure NavigationControl, ScaleControl, and LayerTree are included
• PrintControl.prototype.initialize(map, options) initializes the export process and displays a modal
  • Dimensions (always in landscape)
    • 8.5 x 11 inches
    • 11 x 17 inches
  • File Type
    • PNG
    • PDF
• PrintControl.prototype.exportMap() fires the modal form input

Notes:

Per the Port's request:

• Dimensions are always in landscape
• Legends are only displayed on the 11 x 17
  • Layer names and icons are derived from the Layer Tree
• Export/Print will only export the appropriate aspect ratio from the center of the map - any large boundaries that don't fit within the appropriate aspect ratio will be cropped and ignored
• DIST folder includes minified src

Development:

• yarn
• gulp to run locally on Port 8000 and livereload
• gulp build to build DIST files (js/css)
