Pdf export in Angular Gantt component

PDF export allows exporting Gantt data to PDF document. You need to use the pdfExport method for exporting. To enable PDF export in the Gantt, set the allowPdfExport to true.

To export data to PDF document, inject the PdfExport module in Gantt.

Note: Currently, we do not have support for exporting manually scheduled tasks.

Exporting Gantt data as a blob object

In Gantt, you can export the Gantt chart data as a blob object, which allows you to preview or modify the data before exporting it.

To export the Gantt chart data as a blob object, follow these steps:

step 1: pdfExport fourth argument set as true.

step 2: Then , pdfExpComplete return as blob object.
