Lambda code:
import boto3
import os
from PIL import Image
from io import BytesIO
s3 = boto3.client('s3')
ses = boto3.client('ses', region_name='us-east-1')
def resize_image(image_data):
image = Image.open(BytesIO(image_data))
image = image.resize((512, 512))
buffer = BytesIO()
image.save(buffer, format="png")
return buffer.getvalue()
def lambda_handler(event, context):
bucket_name = event['Records'][0]['s3']['bucket']['name']
object_key = event['Records'][0]['s3']['object']['key']
Download the image from S3
response = s3.get_object(Bucket=bucket_name, Key=object_key)
image_data = response['Body'].read()
Resize the image
resized_image = resize_image(image_data)
Upload the resized image back to S3
resized_key = f"resized/{object_key}"
s3.put_object(Bucket=bucket_name, Key=resized_key, Body=resized_image, ContentType=response['ContentType'])
Send an email notification
email_response = ses.send_email(
Source='[e-mail]',
Destination={'ToAddresses': ['[e-mail]']},
Message={
'Subject': {'Data': 'Image Processed'},
'Body': {'Text': {'Data': f'Your image has been resized and is available at s3://{bucket_name}/{resized_key}'}}
}
)
return {
'statusCode': 200,
'body': f'Resized image saved to s3://{bucket_name}/{resized_key} and email notification sent.'
}
