18. A method for optimizing a source document comprising a plurality of pages of content, the method comprising: obtaining a source document, wherein the source document comprises markup information for a plurality of pages of content; creating an optimized document corresponding to the source document; and for each page in the source document: creating a page record for the page, each page record comprising the reflowable content for that page, wherein the page record comprises references to drawing representations of contours and vertices of textual content in the source document; for each set of values in the page record: selectively filtering the set of values to minimize the storage requirement for the set of values, wherein at least some of the values comprise references to drawing representations of the contours and vertices of textual content in the source document; wherein selectively filtering the set of values to minimize the storage requirement for the set of values comprises: establishing a base value for the set of values and adjusting the values in the set to be offsets from the base value; and from the base value, further adjusting each value in the set as a relative offset of its previous value in the set of values; compressing the page record using a compression technique; and storing the compressed page record in the optimized document.
