Abstract
A method of creating a file describing a digital image comprises the steps of defining a zoomable area in the image, a zoomable area being defined by its characteristics of location in the image and for which additional data are available, writing the characteristics in a file, and writing in the file a management function for navigation in the image.
Claims39
A method comprising the steps of:
- defining at least one zoomable area in a digital image, a zoomable area being defined by characteristics of location of the area in the image and for which additional data defining the image at a greater quality or resolution are available;
- writing the characteristics of the at least one zoomable area in a first file;
- and
- writing in the first file instructions in a language executable by a client terminal computer, said instructions being adapted to cause the client terminal computer to perform a management function for navigation in the image when executed by the client terminal computer.

A reading method implemented in a client terminal computer, comprising the steps of:
- reading characteristics of at least one zoomable area in a first file, a zoomable area being defined by characteristics of location of said area in a digital image and for which additional data defining the image at a greater quality or resolution are available;
- receiving a navigation instruction for the display of an area of the digital image;
- reading instructions in a language executable by the client terminal computer, in the first file;
- and
- executing said instructions thereby performing a management function for navigation in the image.

A device comprising:
- a defining device configured to define at least one zoomable area in a digital image, a zoomable area being defined by characteristics of location of the area in the image and for which additional data defining the image at a greater quality or resolution are available;
- a characteristic writing device configured to write the characteristics of the at least one zoomable area in a first file;
- and
- a management-function writing device configured to write in the first file instructions in a language executable by a client terminal computer, said instructions being adapted to cause the client terminal computer to perform a management function for navigation in the image when executed by the client terminal computer.
