Signing Image Processing

Signing Image Processing

Signing Image Processing requests is an efficient way to ensure that no unwanted image operation can be executed. Every request needs a valid token in order to be delivered. Secure Token and Image Processing is a powerful setup to transform and deliver images in a secure way. If watermark images are signed correctly, the original base image cannot be accessed anymore. Further, we've extended the existing Secure Token feature with the option to add an IP address.

Canonicalization Explained

Canonicalization can be defined as, "A process for converting data that has more than one possible representation into one standard and approved format." What that means is that every resource on a given website should have a single URL (Uniform Resource Locator) rather than multiple URLs hosting identical content. When websites have more than one URL, they rank lower in search engines and their content may not be as accessible or as popular as it otherwise could be.

Image Processing Supports Focal Point Crop

We've extended our Image Processing service with a new focal point crop feature! It adds to our exisiting crop operation by allowing an image crop and an optional zoom at certain coordinates of the image. The coordinates can be absolute or relative to the image dimensions. An extra debug parameter displays the coordinates on the image in order to find the right position for the crop. Any image processing operation can be used in combination with focal point crop.

In fact, the need for an effective compressing tool may have even grown.

Responsive image techniques, such as the srcset, sizes, and media HTML attributes, allow different scaled images to be delivered based on the size and resolution of the accessing device.
