## Abstract

Image transformation for use in a hybrid distribution architecture with improved performance characteristics is provided herein. The hybrid distribution architecture provides content to clients via a dual source system using a central cloud service and a Content Distribution Network, which uses the cloud service as its source. A client that requests a new rendition of an image provided by a chosen source of the hybrid distribution architecture will have that request handled by the source, and the source may maintain that rendition for future provision. By allowing the client to choose the source and letting that source handle the request, rather than requiring a central service hand the request, the amount of data needed to be transmitted is reduced and the speed of provision of content, modified or not, is improved for the client.

color channel filters;
shadow effects;
pixilation effects;
blur effects;
overlays; and
artistic effects.

### Claim 7 (depends on 1)

The method of claim 1, wherein the image transformation service is configured to remove from the original image at least one transformation selected from the group consisting of:
a hue filters;
saturation filters;
luminosity filters;
color channel filters;
shadow effects;
pixilation effects;
blur effects;
overlays; and
artistic effects.

### Claim 8 (depends on 1)

The method of claim 1, wherein the image transformation service is configured to:
adjust a transparency of the original image;
soften the original image;
sharpen the original image;
adjust a brightness of the original image;
adjust a contrast of the original image;
resize the original image;
crop the original image;
provide a border to the original image;
color swapping the original image;
tilt a perspective of the original image;
change a compression rate of the original image; or
change a file format of the original image.

### Claim 9 (depends on 1)

The method of claim 1, wherein the request for the transformed image includes multiple transformations to apply to the original image.

### Claim 10 (depends on 9)

The method of claim 9, further comprising:
in response to determining that the CDN does not store the transformed image, determining whether the CDN stores an intermediary transformed image, wherein the intermediary transformed image is based on the original image and includes one or more of the multiple transformations;
in response to determining that the CDN stores the intermediary transformed image:
transmitting the intermediary transformed image and the request from the CDN to the image transformation service according to the redirect response;
receiving, at the CDN from the image transformation service, the transformed image based on the intermediary transformed image according to the request; and
transmitting the transformed image from the CDN to the client device.

### Claim 11

A system for providing clients with image transformations when using a hybrid distribution architecture, comprising:
a cloud service, hosting an original image; and
a content distribution network (CDN) in communication with the cloud service, a client device, and an image transformation service, wherein the CDN is configured to:
provide content assets, including the original image, in conjunction with the cloud service, wherein the CDN uses the cloud service as a source from which to cache and tier the content assets;
cache the content assets for provision to the client device without requiring authentication of a client;
receive from the client device a request for an image transformation of the original image;
