Adding Watermark to PDF In Lightning Web Component

Lightning Web

To add a watermark to a PDF in a Lightning Web Component (LWC), follow these steps:

1. Choose a PDF manipulation library like pdf-lib.

2. Install the library using npm.

3. Create a new Lightning Web Component.

4. Use Apex to retrieve the PDF content based on record ID.

5. In the LWC, use JavaScript to manipulate the PDF content using the chosen library. Add a watermark, specifying text, font, color, and position.

6. Save the modified PDF content, either by sending it back to the server or displaying it in the UI. Handle errors, loading indicators, and user feedback appropriately. Consider security and performance implications of processing PDFs on the client or server side.

This approach leverages JavaScript and a third-party library for PDF manipulation, as Salesforce doesn’t natively support PDF generation or manipulation in Lightning components. Ensure to check the library’s documentation and licensing to meet your requirements.

Shekhar is a one stop shop for all your needs in terms of Salesforce. He is an excellent mentor, coaches you with real time industry requirements, guides you for certification examination, job search and how to create an impact during interviews. He helped me immensely while writing a code for an assignment that I had to submit during my selection process at one of the BIG 4's.He never spoon feeds but knows how to put you in the pool so that you start swimming independently. His vast knowledge in Salesforce , promptness and his passion to guide makes you approach him without any hesitation. I would definitely recommend Shekhar for any help in Salesforce!!

Thank you, Shekhar, for all your support and guidance. Your mentorship has been so appreciative. And your training was the best training I've personally ever experience. Your training provided me with such clarity and understanding of Salesforce features that I have had so much difficulty understanding. Keep up the good work

Shekhar sir, I am getting good understanding in apex class , triggers because you have given some nice examples while explaining the concepts Its improving my understanding levels Thanks

I had to take time out to appreciate and thank you for 2 reasons. 1) For being an awesome trainer. It is a challenge to attend class at 10; 30 pm when the mind is sleeping. But you put in the effort to explain concepts which becomes so simple to de-code :). I stay glued in. Thumbs up for that. 2)For being an excellent Leader. When the Boss says GO The leader says Let's go!! Again for going that extra mile to hand hold newcomers and letting go when required.

Hi Shekhar, I really wanted to say thanks to you. When I came to Salesforce from SAP SD , many of my friends said that you made a wrong decision in your career. and also they said without programming background it's going to be really hard for you to get a job in SF. At that time I thought is it so???? weather i made the wrong decision and I thought let's do only Admin in SF. But after joining ur class I was so happy and got the confidence I made aright decision in my career and I can be developer also. really thanks a lot.

I am very happy with the teaching process. Thank you! Due to my work commitments, it’s very difficult for me to attend every session but I go through all the videos. It’s enriching.
