Print and Export in React Maps component

14 Apr 2021 / 5 minutes to read

Print

To use the print functionality, we should inject the Print module into services and set the allowPrint property to true. The rendered map can be printed directly from the browser by calling the method print.

Export

Image Export

To use the image export functionality, we should inject the ImageExport module into services and set the allowImageExport property to true. The rendered map can be exported as an image using the export method. The method requires two parameters: image type and file name. The map can be exported as an image in the following formats.

JPEG
PNG
SVG

We can get the image file as base64 string for the JPEG and PNG formats. The rendered map can be exported to image as a base64 string using the export method. There are four parameters required: image type, file name, orientation of the exported PDF document which must be set as null for image export and finally allowDownload which should be set as false to return base64 string.

PDF Export

To use the PDF export functionality, we should inject the PdfExport module into services and set the allowPdfExport property to true. The rendered map can be exported as PDF using the export method. The export method requires three parameters: file type, file name and orientation of the PDF document. The orientation setting is optional and “0” indicates portrait and “1” indicates landscape.

Export the tile maps

The rendered map with providers such as OSM, Bing and Google static maps can be exported using the export method. It supports the following export formats.

JPEG
PNG
PDF
