Overview

The ImageProcessor service is an Image utility service on the Cloud. Developers can upload files on the cloud and perform various Image Manipulation operations on the Uploaded Images e.g. resize, scale, thumbnail, crop etc. It is especially useful for Mobile Apps when they dont want to store Images locally and dont want to perform processor intensive operations. It is also useful for web applications who want to perform complex Image Operations

#thumbnail_stream(name, imagePath, width, height) ⇒ Object

Creates a thumbnail of the image via Stream. There is a difference between thumbnail and resize The thumbnail operation is optimized for speed, it removes information of the image which is not necessary for a thumbnail e.g header information. Returns the original image url and converted image url. Images are stored on the cloud and can be accessed through the urls Resizing is done based on the width and height provided

Parameters:

  • name —

    • Name of the image file for which thumbnail has to be created

  • inputStream —

    • InputStream of the local file whose thumbnail has to be created

  • width —

    • Width of the image for thumbnail

  • height —

    • Height of the image for thumbnail

Returns:

  • Image object containing urls for the original and converted images

Raises:

  • App42Exception
