String array $format [, string $orientation = self::ORIENTATION_PORTRAIT ] ): array Returns a normalized format by a page format name or by an array. Parameters $format: string array The format as an array with 2 values or a pre-defined format constant $orientation: string The orientation Return Values Array where the keys '0' and 'width' are the width and keys '1' and 'height' are the height. Exceptions Throws Page Boundaries A PDF page may define up to five separate boundaries that all define a boundary for a specific medium or region on that medium. Such boundaries are needed to distinguish between an intermediate medium and a finished medium. The boundaries are defined as class constants in the SetaPDF-Core component.

String $name): boolean Checks if a name is a valid page boundary name. Parameters $name: string The boundary name Return Values A boolean value whether the name is valid or not. The boundary boxes of a page are accessable via a SetaPDF_Core_Document_Page instance.

Compare or Check for a Specific Format To check an existing page or rectangle against a predefined format (like A4 or Letter) looks like an easy job but becomes tricky when you notice that different PDF creators use different values for the same formats. Some round up or down in their convertion from e.g. Mm to points or simply round to full integers while others round the values to two digits. We integrated a simple helper method that allows you to compare formats by using a difference threshold. String array $format, array $rect [, int float $threshold = 1 ] ): boolean string Checks if a rectangle is approximately the same size as a given format. Parameters $format: string array The format as an array or as one of the defined page formats $rect: array The rectangle or the page that needs to be compared $threshold: int float The allowed difference between the rectangle and the format Return Values false or a string containing the matched orientation.

By Professor Pat McKeown Cranfield Precision Engineering, UK Member of Joint Organising Committee IPES6/UME2 PROGRESS IN PRECISION ENGINEERING Metal working companies in tool making, prototype manu­ facture and subcontract machining often use the label 'precision engineering' to indicate that they are accustomed to working to finer tolerances than is normally expected in series production. But what we are concerned with in this and our preceding international conferences is much wider and deeper than this. Precision engineering is a grouping of multidis­ ciplinary scientific and engineering skills and techniques, firmly based on dimensional metrology, by which a wide range of new advanced technology products is made possible.

In the last 5 - 10 years we have witnessed dramatic progress in precision engineering, particularly by the rapid development of its important sub-sets, micro-engineering and nanotechnology.

I t is a part icular pleasure for me and my colleagues on the Organising Committee to welcome you to Braunschweig on the occasion of this the first joint international meeting in high precision manufacturing/precision engineering to be held in Germany. Our aim is to bring together the world's leading precision engineering practitioners from areas of application as diverse as optics for astronomy, micro and nano machining process research, design and development of ul tra preclslon machine tools and metrology equipment, advanced materials, bio­ medical research and new sensor/transducer systems.
