template-body file://buckets-cloudformation.yml Next, we'll create the stack: aws cloudformation create-stack \ Remember: replace my-lambda-function-code and my-images with unique bucket names. 1) Creating the AWS S3 Bucketsįirst, we'll create a CloudFormation stack for the S3 buckets we need: Otherwise, let's create our skeletal Lambda function. between -resize and -size, and - between -repage and -page If I want to convert some png files to a pdf file, and change the size of images (as number of pixels, or as some standard page size such as A4), which options shall I use (It seems like -page a4 works as it intends to, while -repage a4 doesn't make any change. Extracts DCT features from either uint8, uint16 or double arrays. If you already have an AWS Lambda function, you can skip forward to "part 2". Resize to specific dimensions and keep aspect ratio. The size of the blocks, in which the image is decomposed.
