PDFToImageConverter

Convert pdf file to image

Download trim.js
Open terminal, Enter

cd AWS-trim-master

In the AWS-trim-master folder create node_modules folder
Now enter following code in terminal

npm install async gm fs mktemp bluebird request docx-pdf-pagecount

The AWS Lambda runtime already has the AWS SDK for JavaScript in Node.js, So we don't need to install AWS SDK.
Select trim.js & node_modules folder and create a zip file.
In AWS, create a lambda function and upload this zip in Function code section, Change the HandlerInfo name to trim.handler.
Entert the Environment values of Client_Identifier, Instance_URL & Result_File_Name.
In the designer section, add trigger S3 bucket to your AWS lambda function.
Now when ever you upload a file to bucket, you can see the new folder with converted images.
Following is an example test event, (update s3 bucket name, key, file size & file etag )
