Abstract: Method of cropping digital images and ordering of the cropped digital images advantageously uses the Print Wizard application of a computer operating system. The method modifies the Print Wizard application to include a cropping tool application written in a client sided scripted language which modifies the Print Wizard application to provide a user controlled cropping tool for imulating the cropping of digital images. The operating system can receive the cropping application by downloading of the cropping application from a photographic print server when the personal computer initiates contact with the print server. It is also possible that the Print Wizard has previously been modified by having the cropping application as part of the Print Wizard application initially or having previously been modified. The modified Print Wizard application allows modification by simulating a form of cropping and deriving cropping instructions associated with particular digital images.

Abstract: The present method renders scan lines of an image to an output device in a memory efficient manner and in a manner suitable for a client server application using an Internet or Intranet type network. The image is defined by a number of order objects, each of which is independently stored. The procedure determines on a scan line basis the objects which influence the particular scan line and accumulates the rendering effect of the objects necessary for returning the scan line. Returned scan lines are transmitted over a network to a client computer and the procedure is repeated. Objects are only partially rendered as required to pass on the necessary information as input for the next object. This approach maintains the independence of the objects, allows interaction of objects, allows output to high resolution output devices in a memory efficient manner, and allows each object to be reproduced at the best resolution and in an efficient manner for a large scale network application.
