- Defined in:
- lib/imageProcessor/ImageProcessorService.rb
#thumbnail(name, imagePath, width, height) ⇒ Object
Creates a thumbnail of the image. 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
