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
.

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.

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.

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.

Note: The exporting of the map as base64 string is not supported in the PDF export.
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.
