, our image management solution, allows you to dynamically and transparently restrict the maximum size (Content-Length
) of your images by applying a progressive degradation in their quality.
To achieve this, we use our TCDN-i3-transform
header, specifying the desired operation type, which in this case is max_length.
Unlike other operations, such as , this operation requires a mandatory parameter: the maximum size that the resulting image will have. This parameter has the format <size>[<unit>]
, where if no unit is specified, it is implicitly assumed to be in bytes. The accepted values for <unit>
are b
(bytes), k
(kilobytes), and m
(megabytes). For example, a valid value could be 640k.
The exact syntax for this operation is as follows: max_length:<size>[<unit>].
Unlike the operation, this operation is not restricted to a specific image format.
For instance, if you wanted all the images in your domain mi-dominio.es
under the URL /estaticos/imagenes
to be served with a maximum size of 1 MiB, you would simply deploy a configuration similar to the following from the :
