HI Priyanka,

Tweak the below code as per your requirement to display the same as PDF.

The below code displays the attachment using a visual force page. 
Use the below controller and Visual force page  :


Apex Class

Public Class displayImageExtension {

    String recId;
    
    public displayImageExtension(ApexPages.StandardController controller) {
        recId = controller.getId();    
    }
    
    public String getFileId() {
        String fileId = '';
        List<Attachment> attachedFiles = [select Id from Attachment where parentId =:recId order By LastModifiedDate DESC limit 1];
        if( attachedFiles != null && attachedFiles.size() > 0 ) {
            fileId = attachedFiles[0].Id;
        }
        return fileId;    
    }
}

 

 

Visual Force Page

 

<apex:page standardController="Account" extensions="AccountImageController">
<apex:form >
<apex:image url="/servlet/servlet.FileDownload?file={!FileId}"/>
</apex:form>
</apex:page>

 

Please let me know If you need any help regarding the same .
Hope this helps.

Mark this as solved if the reply was helpful.

Thanks,
Nagendra
