Line primitives -geometric degeneracies

References:

9.5.4.3

Geometric degeneracies are: Permitted Yes; Prohibited No;

If permitted, graphical meaning of the degeneracy: A line primitive element, whose entire locus is a single point, denotes a graphical dot which is a filled circle, with diameter equal to the current line width and colour equal to the current line colour.

Other: None.

T.14.3

Same as Model Profile: Yes

Filled area primitives -

geometric degeneracies

References:

9.5.4.4

Geometric degeneracies are: Permitted Yes; Prohibited No;

If permitted, graphical meaning of the degeneracy: A filled-area primitive element, whose entire locus is either a single point or a line has the following meaning:

- If the locus of a filled-area primitive is a single point, then the meaning is a dot (which is a filled circle).

- If the locus of a filled-area primitive is a non-degenerate line segment, then the meaning is a line.

The dot or line is displayed with the fill colour if EDGE VISIBILITY is 'off', unless INTERIOR STYLE is 'empty', in which case it is not rendered. If EDGE VISIBILITY is 'on', the interior treatment is the dot or line displayed in the fill colour, and then a dot or line superimposed with the current edge attributes.

Other: None.

T.14.4

Same as Model Profile: No

Graphical text strings

References:

9.5.4.5

Minimum string length (bytes): 0

Maximum string length (bytes): 254

Any restrictions on the use of ISO/IEC 2022 switching controls?

The C0 character NUL (code value) is permitted and has no effect. String parameters of graphical text shall contain no control character (7/8 bit codes: 1-31 and 128-159). ISO/IEC 2022 switching is not allowed in graphical text. A valid WebCGM metafile may use for graphical text only the character encodings (CGM "character sets"): the collection of four character encodings which comprise ISO Latin1 and Symbol (see CHARACTER SET LIST); Unicode UTF-8; and UTF-16.

Other: None.

Note. According to the Binary Encoding of CGM:1999, strings of multi-byte Unicode text are "big-endian", like the rest of the binary metafile.

Minimum string length (bytes): 0.

Maximum string length (bytes): 254.

Any restrictions on the use of ISO/IEC 2022 switching controls? C0 control codes (except NUL and ISO/IEC 2022 switching) are prohibited.

Any character set used in the metafile which is accessed by ISO/IEC 2022 switching techniques shall be in the Character Set List (defined in this profile).

Other: None.

T.14.5

Same as Model Profile: No

Non-graphical text strings

References:

9.5.4.6

Maximum string length (bytes):

for type SF: 254

for type SF within type D: 1024

Format effectors and ESC: Permitted Yes; Prohibited No;

Note: according to CGM:1999, the format effectors are NUL, CR, LF, BS, HT, VT, and FF.

Other C0 control codes (except NUL and ISO/IEC 2022 switching) are prohibited.

Any limits on the set of acceptable character encodings (CGM "character sets")? The permitted character encodings (CGM "character sets") for non-graphical text are ISO Latin 1 (LHS & RHS), and UNICODE UTF-8, and Unicode UTF-16. Only one of these three shall be used throughout any particular WebCGM metafile instance. According to the CGM standard, the default SF character encoding ("set"), at the beginning of the 'metafile id' parameter of the BEGIN METAFILE element is ISO Latin 1. If the metafile is to use UTF-8 for SF parameters, then the following 4-octet ISO 2022 sequence shall occur as the first 4 octets of the 'metafile id' parameter:

ESC 2/5 2/15 4/9

If the metafile is to use UTF-16 for SF parameters, then the following 4-octet ISO 2022 sequence shall occur as the first 4 octets of the 'metafile id' parameter:

ESC 2/5 2/15 4/12

Otherwise, the use of ISO 2022 switching is prohibited in non-graphical text string.

NOTE: Section 6.3.4.5 of CGM:1999 allows the switching to UTF-8 (variable length multi-byte), and allows the use of 8-bit access to the ISO Latin 1 set.

Any restrictions on the use of ISO/IEC 2022 switching controls?

Any character encodings (CGM "character sets") used in the metafile which is accessed by ISO/IEC 2022 switching techniques shall be in the character set list (defined in this profile).

Other: See 3.1.1 for additional restrictions to the character repertoire for those WebCGM non-graphical strings which may be part of the WebCGM IRI fragment.

Note. According to the Binary Encoding of CGM:1999, strings of multi-byte Unicode text are "big-endian", like the rest of the binary metafile.

Maximum string length (bytes):

for type SF: 254.

for type SF within type D: 1024.

Format effectors and ESC: Permitted Yes; Prohibited No;

Other C0 control codes (except NUL and ISO/IEC 2022 switching) are prohibited.

Any limits on the set of acceptable character sets? The permitted character sets are ISO 8859-1 LHS No.1 and ISO 8859-1 RHS No.1.

Any restrictions on the use of ISO/IEC 2022 switching controls?

Any character set used in the metafile which is accessed by ISO/IEC 2022 switching techniques shall be in the character set list (defined in this profile).

Element is: Required No; Permitted Yes; Prohibited No;

This element is required for all metafiles containing graphical text.

Note. The terminology "character set", used in the original ISO CGM:1987 specification and preserved through CGM:1999, is considered inaccurate by contemporary standards. The current correct terminology is character encoding, defined in the [CHARMOD] standard.

Maximum limit for the number of character sets in the character set list: 6.

Allowable character sets:

"94-character G-set", 4/2 (ISO 8859-1 LH);

"96-character G-set", 4/1 (ISO 8859-1 RH);

"94-character G-set", 2/10 3/10 (Symbol LH);
