Image Upload Resize

This sample demonstrates how to respond to an EventGridEvent published by a storage account to resize an image and upload a thumbnail as described in the article Automate resizing uploaded images using Event Grid.

Local Setup

Before running this sample locally, you need to add your connection string to the AzureWebJobsStorage value in a file named local.settings.json file. This file is excluded from the git repository, so an example file named local.settings.example.json is provided.

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "<STORAGE_ACCOUNT_CONNECTION_STRING>",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "THUMBNAIL_CONTAINER_NAME": "thumbnails",
    "THUMBNAIL_WIDTH":  "100",
    "datatype": "binary"
  }
}

To use this file, do the following steps:

  1. Replace <STORAGE_ACCOUNT_CONNECTION_STRING> with your storage account connection string
  2. Rename the file from local.settings.example.json to local.settings.json
