You can delete annotations from a PDF file using Aspose.PDF for Node.js via C++. In case you want to delete annotations from a PDF, you can use AsposePdfDeleteAnnotations function. Please check the following code snippet in order to delete annotations from a PDF file in Node.js environment.
CommonJS:
- Call
require
and importasposepdfnodejs
module asAsposePdf
variable. - Specify the name of the PDF file from which the annotation will be removed.
- Call
AsposePdf
as Promise and perform the operation for removing annotations. Receive the object if successful. - Call the function AsposePdfDeleteAnnotations.
- Delete annotations. Thus, if ‘json.errorCode’ is 0, the result of the operation is saved in “ResultPdfDeleteAnnotations.pdf”. If the json.errorCode parameter is not 0 and, accordingly, an error appears in your file, the error information will be contained in ‘json.errorText’.
const AsposePdf = require('asposepdfnodejs');
const pdf_file = 'Aspose.pdf';
AsposePdf().then(AsposePdfModule => {
/*Delete annotations from a PDF-file and save the "ResultPdfDeleteAnnotations.pdf"*/
const json = AsposePdfModule.AsposePdfDeleteAnnotations(pdf_file, "ResultPdfDeleteAnnotations.pdf");
console.log("AsposePdfDeleteAnnotations => %O", json.errorCode == 0 ? json.fileNameResult : json.errorText);
});
ECMAScript/ES6:
- Import the
asposepdfnodejs
module. - Specify the name of the PDF file from which the annotation will be removed.
- Initialize the AsposePdf module. Receive the object if successful.
- Call the function AsposePdfDeleteAnnotations.
- Delete annotations. Thus, if ‘json.errorCode’ is 0, the result of the operation is saved in “ResultPdfDeleteAnnotations.pdf”. If the json.errorCode parameter is not 0 and, accordingly, an error appears in your file, the error information will be contained in ‘json.errorText’.
import AsposePdf from 'asposepdfnodejs';
const AsposePdfModule = await AsposePdf();
const pdf_file = 'Aspose.pdf';
/*Delete annotations from a PDF-file and save the "ResultPdfDeleteAnnotations.pdf"*/
const json = AsposePdfModule.AsposePdfDeleteAnnotations(pdf_file, "ResultPdfDeleteAnnotations.pdf");
console.log("AsposePdfDeleteAnnotations => %O", json.errorCode == 0 ? json.fileNameResult : json.errorText);
