Multi-image composition and XML or JSON manifest building

Multi-image composition and XML or JSON manifest building To write a PHP script which works with the main Web browsers for interactive selection and arranging of possibly overlappping images on the screen. A manifest would be written to a file in XML or JSON format. It would describe each image in the composition with its attributes and role in the composition. The user should be able to: - name the image composition - specify canvas size in pixels - select images for the composition from the file system or the Web - after an image is on the canvas ability to move, resize and delete it from a composition - add/change a comment about the composition and about each image - add/change tool tip information about each image - default: the fully qualified file name/Web address - specify if the composition's manifest is to be saved in XML or JSON format (see below) - request SAVING the composition. At that time the user would be presented with a list of all the images in the composition along with all their attributes. Each entry would include the associated image's thumbnail. - load a previous composition and be able to do all of the above with it Manifest frmat in XML - conceptually smilar in JSON # indicates comments only for this description <COMPOSITION # at beginning of file NAME=”compositionName” # “compositionName” as defined by user CANVASSIZE=”x,y” # user secified canvas size in pixels \> <IMAGE NAME=”imageName” # as named by user AT=”x,y” # x,y pixel address of bottom left corner on the # composition “canvas”, [LAYER=”layer”] # allows controlled overlay of images via an # image “layer” metaphor. Lowest number layer is # on bottom and highest umber layer on top # DEFAULT = “1”. If 2 or more images are at the # same layer and overlap then the results are # unpredictable SIZE=”imageSize” # x,y image size in pixels as determined by the # program for images loaded from the file system. # User can enter image size for Web based images [SCALE=”scalingFactor”] # image scaling specified by % or as pixels along # the scaled image horizontal dimension. # Aspect ratio is preserved IMAGE=”imageAccessName” # image's fully qualified file name or Web address [TOOL TIP=”toolTipText” # optional descriptive text. XML special characters # are either not accepted or are escaped [NOTE=”note”] # optional note/comment. XML special characters # are either not accepted or are escaped /> </COMPOSITION > # at end of file
