Merge PS documents to PDF

Steps to merge PostScript files with JavaScript

1. Create file reader ‘const file_reader = new FileReader();’ and read file ‘file_reader.readAsArrayBuffer(e.target.files[0]);’
2. Load needed files by using AsposePagePrepare .
3. After the loading of the last file, call AsposePSMergeToPdf and pass the array of file names, the result file name, and SuppressError boolean values to it.
4. The result JSON contains the file name in fileNameResult. If the SuppressErrors value was true, as it is by default, it is possible to see what errors were thrown during the merge of EPS to PDF.
5. You can download files by using the DownloadFile function: ‘DownloadFile(json.fileNameResult, ‘image/pdf’);’

var fPs2Pdf = function (e) {
 	 const file_reader = new FileReader();
 	 file_reader.onload = (event) => {
 	 function readFile(index) {
 	 	 if (index >= e.target.files.length) {
 	 	 	 const fileNames = Array.from(e.target.files).map((x) => x.name).toString();
 	 	 	 const json = PSMergeToPdf(fileNames, 'ResultMerge.pdf', true);
 	 	 	 if (json.errorCode == 0) {
 	 	 	 	 DownloadFile(json.fileNameResult, 'image/pdf');
 	 	 	 }
 	 	 	 else
 	 	 	 	 document.getElementById('output').textContent = json.errorText;
 	 	 	 return;
 	 	 }
 	 	 const file = e.target.files[index];
 	 	 file_reader.onload = function (event) {
 	 	 	 AsposePagePrepare(event.target.result, file.name);
 	 	 	 readFile(index + 1);
 	 	 }
 	 	 file_reader.readAsArrayBuffer(file);
 	 }
 	 readFile(0);
 }

Merge Encapsulated PostScript files with JavaScript

To merge EPS to PDF you will need to take the same steps as for PS to PDF merging. To learn a more detailed code example, go to Aspose.Page Documentation .
