Export the document as pdf in client-side

Use pdf export component in application level to export the document as pdf using exportasimage API. Here, all pages will be converted to image and inserted as pdf pages(works like print as PDF). There is one limitation we can’t search the text because we are exporting the pdf as image.

Note: You can install the pdf export packages from this link.

Export document as pdf in server-side using Syncfusion DocIO

With the help of Synfusion DocIO, you can export the document as Pdf in server-side. Here, you can search the text.

The following way illustrates how to convert the document as Pdf:

  • Using serialize API, convert the document as Sfdt and send it to server-side.

The following example code illustrates how to convert the document to sfdt and pass it to server-side.

<button id='export' v-on:click="onClick">Export</button>
  <ejs-documenteditorcontainer ref='container' :serviceUrl='serviceUrl' height="590px" id='container' :enableToolbar='true'></ejs-documenteditorcontainer>
</div>
</template>
<script>
  import Vue from 'vue';
  import { DocumentEditorContainerPlugin, DocumentEditorContainerComponent,Toolbar} from '@syncfusion/ej2-vue-documenteditor';

  Vue.use(DocumentEditorContainerPlugin);

  export default {
data() {
  return { serviceUrl:'https://ej2services.syncfusion.com/production/web-services/api/documenteditor/'
  };
},
provide: {
  //Inject require modules.
  DocumentEditorContainer: [Toolbar]
},
methods: {
 onClick:function() {
let obj = this;
let http = new XMLHttpRequest();
// Replace your running web service Url here
http.open('POST', 'http://localhost:62869/api/documenteditor/ExportPdf');
http.setRequestHeader('Content-Type', 'application/json;charset=UTF-8');
http.responseType = 'json';
//Serialize document content as SFDT.
let sfdt = { content: obj.$refs.container.ej2Instances.documentEditor.serialize() };
//Send the sfdt content to server side.
http.send(JSON.stringify(sfdt));
}
}
  };
</script>
  • Using Save API in server-side, you can convert the sfdt to stream.
  • Finally, convert the stream to Pdf using Syncfusion.DocIORenderer.Net.Core library.

The following example code illustrates how to process the sfdt in server-side.

[AcceptVerbs("Post")]
[HttpPost]
[EnableCors("AllowAllOrigins")]
[Route("ExportPdf")]
public void ExportPdf([FromBody]SaveParameter data)
{
// Converts the sfdt to stream
Stream document = WordDocument.Save(data.content, FormatType.Docx);
Syncfusion.DocIO.DLS.WordDocument doc = new Syncfusion.DocIO.DLS.WordDocument(document, Syncfusion.DocIO.FormatType.Docx);
//Instantiation of DocIORenderer for Word to PDF conversion
DocIORenderer render = new DocIORenderer();
//Converts Word document into PDF document
PdfDocument pdfDocument = render.ConvertToPDF(doc);
// Saves the document to server machine file system, you can customize here to save into databases or file servers based on requirement.
FileStream fileStream = new FileStream("sample.pdf", FileMode.OpenOrCreate, FileAccess.ReadWrite);
//Saves the PDF file
pdfDocument.Save(fileStream);
pdfDocument.Close();
fileStream.Close();
document.Close();
}
