Abstract: A composite document is scanned for the existence of fields or placeholders or other information input areas, so that their disposition within the composite document and other properties, are collated. Object placeholders (which might be a rectangle object for example) may then replace fields or placeholders or information input areas within in the document. This is to suitably create “whitespace” for an equivalent appropriate field, control or widget to be rendered in that space such as in a Web presentation. After this, the composite document is rasterised to create one or more pixmap pages. The pixmaps are then sent to a user device via a computer network for display in a program such as a Web browser, along with any properties relating to the fields, placeholders or other information input areas that were detected in the composite document.
