skipper-s3-resizer v1.0.2

skipper-s3-resizer

This is extended skipper-s3-resizer based on - Original skipper-s3-resize

New features

Adds optional configurations:

• prefix - S3 object prefix (Default: '')
• filename - Custom function for naming files to be uploaded (Default: <uuid>.<ext>).
• stretch - Whether to stretch or cover image (Default: false).

Changed resizing technique:

• If width and height are not specified, image will be uploaded in original size
• If only one dimension is specified, downscale (keeps aspect-ratio)
• If both dimensions are specified
  • And stretch == true, downscale (breaking aspect-ratio)
  • And stretch == false, downscale (cover)

Based on SailsJS Skipper S3 adapter for receiving upstreams with a twist: Images will be resized before uploading using GraphicMagick.
