Patent number: 7571433Abstract: The specification describes a program used to optimize journal files such as metafiles used in the Microsoft® Windows® programming environment. The program steps through instructions from the original journal file and selectively emits the instructions to an optimized metafile using several optimization techniques. One such technique is to defer the emission of any state modification instruction until such emission is actually required by a subsequent instruction that is dependent on the state modification instruction. For instance, resource creation and selection instructions are not emitted until the specified resource is actually used. Another technique is to indefinitely defer the emission of any state modification instruction that would merely duplicate the currently existing effect of previously emitted state modification instructions.Type: GrantFiled: February 24, 2005Date of Patent: August 4, 2009Assignee: Microsoft CorporationInventor: Gordon T.

Patent number: 6621493Abstract: A Windows® metafile is compressed by first processing individual records. In some types of records, record type indicators are mapped to values having fewer significant bits than the original record type indicators. In addition, record length indicators are removed in some record types because they are constant values. In record types where the length varies, the record length indicator is divided to reduce its number of significant bits. There are also record types having one or more arguments that rarely change. For records of these types, the arguments are removed. There are other types of records whose arguments are often repeated from previous records of the same type. When this is the case, the arguments are removed. Many metafile arguments specify graphics coordinates in terms of absolute values. These absolute values are converted to relative values. In most cases, this reduces the number of significant bits required by the values.Type: GrantFiled: February 17, 1999Date of Patent: September 16, 2003Assignee: Microsoft CorporationInventor: Gordon T.
