Defect Report concerning IS 8632:1992 Computer Graphics: Metafile for the storage and transfer of picture description information (CGM) Part 4, Clear text encoding.

Qualifier (e.g. error, omission, clarification required): Clarification.

References in document (e.g. page, clause, figure and/or table numbers):

p 47 , clause 6.6, Interpolated Interior

Nature of defect (complete, concise explanation of the perceived problem):

In the encoding of Interpolated Interior there are a number of errors.

(1) The 2 lines starting "<<V:X>" are separated with a "|" (OR), and they need to be

enclosed with one more <...> so that the two lines become a single production < 1st |

2nd >.

Fix: on the "{parallel}" line, prepend "<", and on the next line put ">" just after the "(2)". So the two lines become:

<<<V:X><SEP><V:Y>>(1) {parallel}

| <<V:X><SEP><V:Y>>(2)> {elliptical,triangular}

(2) The parameter "number of stages" is missing.

Fix: after the line with "{elliptical,triangular}" add "<SEP><I:NBROFSTAGES>".

(3) Replace :<<SEP><K:REFCOLRLIST>>(m) with <<<SEP><K:REFCOLRLIST>>(m+1) {parallel,elliptical} | <<SEP><K:REFCOLRLIST>>(3)> {triangular}

Make changes indicated above.

Editor's response (any material proposed for processing as a technical corrigendum to, an amendment to, or a commentary on the International Standard or DIS final text is attached separately to this completed report):

Amend the standard as proposed above.
