Feature Type

Symbology Instruction

Comments

Points

CS(SOUNDG02,
DEPTH_ATTRIBUTE,
FEATURE_CODE)

(S-52 only)

This code is a call to a conditional symbology procedure, used only for drawing soundings type point features.

Note: DEPTH_ATTRIBUTE and FEATURE_CODE are parameters of the SOUNDG02 procedure.

SOUNDG02: the conditional symbology procedure used to display depth values for point objects. As a procedure call, this parameter is a literal value which must be included in the instruction as SOUNDG02.

DEPTH_ATTRIBUTE: the sounding feature attribute from which the sounding value is retrieved (for example, VALSOU).

FEATURE_CODE: the feature code used (for example, SGSL).

SY(FEATURE_CODE)

(paper charts only)

This code is used for drawing a symbol using the specified feature code in the ih_master.txt file.

If the feature code does not exist in the master file or in invalid for symbols, a ? character is used instead.

SY(FEATURE_CODE, ORIENT)

(paper charts only)

This code is similar to the above, except that it can assign an angular distance measured from true north (north azimuth). This can be the value of the attribute (typically ORIENT) or an explicit number.

Points (cont’d)

TE, TX (STRING, HJUST,
VJUST,SPACE,CHARS,
XOFFS,YOFFS,COLOUR,
DISPLAY)

(S-52 only)

The TE code is used for numeric only text, such as soundings.

The TX code is used for alphanumeric text.

STRING: text string

HJUST: horizontal justification
1 - centre
2 - right
3 - left (default))

VJUST: vertical justification
1 - bottom (default)
2 - centre
3 - top

SPACE: character spacing
1 - fit (characters are expanded or compressed to
fit the current field width)
2 - standard (CHARS attribute typeface and
spacing is used) (default)
3 - standard with word wrap (CHARS attribute
typeface and spacing is used, text longer than
8 characters is split to fit onto separate lines).

CHARS: character specification
- defines style (font), weight, width (straight,
italic), and text character size.
- Style: 1 - a plain, sans serif font (recommended)
- Weight: 4 - light, 5 - medium (default), 6 - bold
- Width: 1 - upright (non-italic, recommended); for
ENC $CHARS attributes, set value to 2)
- Body Size: 10 - uppercase character height
(measured in pica points; 10 pica (default)
= 3.51mm; this is the minimum size).

XOFFS: X-offset of the pivot point, measured in the units used for Body Size (see CHARS).
0 (default value): undefined
+ (value greater than zero): right offset
- (value less than zero): left offset
Note: offset = value * Body Size

YOFFS: Y-offset of the pivot point, measured in the units used for Body Size (see CHARS)
0 (default value): undefined
+ (value greater than zero): downward offset
- (value less than zero): upward offset
Note: offset = value * Body Size

COLOUR: 5-character colour token.

DISPLAY: text grouping, if any, for the selection.

Lines

LC(FEATURE_CODE)

(paper charts only)

This code draws a complex line using the feature code specified in the ih_master file.

Line ends are drawn as retangular or rounded, according to the feature code in ih_master.txt. If the feature code does not specify a line-end style, rectangular is used as the default.

If the $capsy (cap style) attribute for the line feature is set, this value overrides the feature code settings in ih_master.txt.

If the feature code does not exist in the master file or in invalid for symbols, a ? character is used instead.

The LC code is the preferred code for line drawing.

LS(SOLD, 1, COLOUR_TOKEN)

(paper charts only)

This code draws a line. The first parameter can be SOLD (solid), DOTT (dotted line), or DASH (dashed line).

The second parameter is the width of the line (in pixels).

The third parameter is the colour token.

If the $capsy (cap style) attribute for the line feature is set, this value overrides the settings in line lookup table.

The default line end is rectangular.

LC(FEATURE_CODE)

(S-52 only)

This code draws a line using a feature code specified in LIN (.lin) file in symshow folder.

If the $capsy (cap style) attribute for the line feature is set, this value overrides the feature code settings.

LS(SOLD, 1, COLOUR_TOKEN)

(S-52 only)

This code draws a line. The first parameter can be SOLD (solid), DOTT (dotted line), or DASH (dashed line).

The second parameter is the width of the line (in pixels).

The third parameter is the colour token.

The default line end is rounded.

SY(FEATURE_CODE, ORIENT)

(S-52 only)

This code is used for drawing a symbol in the middle of a line.

This is the same code as used for point symbolization. See the Points section for more information.

Areas

AC(COLOUR_TOKEN)

(S-52 and paper charts)

This code specifies the colour token name from ih_colour.xml.

AC(COLOUR_TOKEN,
TRANSPARENCY_VALUE)

(S-52 and paper charts)

The second parameter is used to define transparency (1=25%, 2=50%, 3=75%).

This feature is not yet supported: only solid colours are drawn.

AH(COLOUR_TOKEN,STYLE,
THICKNESS,SPACING)

(paper charts only)

The STYLE parameter sets the hatch pattern:

• BackDiagonal

• Cross

• DiagonalCross

• ForwardDiagonal

• Horizontal

• Vertical

The default value is ForwardDiagonal. All hatch style values are case sensitive

The third parameter sets the thickness of the hatch lines. The default value is 0.01 mm.

The fourth parameter sets the spacing between the hatch lines. The default value is 1.0 mm.

AP(FEATURE_CODE)

(paper charts only)

The pattern fill name used to reference pattern fill definitions (not yet supported).

LC(FEATURE_CODE)

(paper charts only)

For definitions, see the Lines type section.

LS(SOLD,1,COLOUR_TOKEN)

(paper charts only)

For definitions, see the Lines type section.

SY(FEATURE_CODE, ORIENT)

(paper charts only)

For definitions, see the Points type section.

TB(FILL_COLOUR,
OUTLINE_COLOUR,
OUTLINE_WIDTH,
MARGIN_RIGHT_MM,
MARGIN_LEFT_MM,
MARGIN_TOP_MM,
MARGIN_BOTTOM_MM)

(paper charts only)

Draw a text box around the text feature.

FILL_COLOUR: background colour
OUTLINE_COLOUR: border colour
MARGIN_RIGHT_MM: distance of the right-hand side of the margin in millimetres.
MARGIN_LEFT_MM: distance of the left-hand side of the margin in millimetres.
MARGIN_TOP_MM: distance of the top-side edge of the margin in millimetres.
MARGIN_BOTTOM_MM: distance of the right-side edge of the margin in millimetres.

TH(COLOUR,WIDTH_MM)

(paper charts only)

Draw a halo around each character of the text feature.

The first parameter is the colour token.

The second parameter is the width of the halo line around each text character. The halos are drawn underneath the characters of the text.

TS(SYMBOL_NAME,SIZE_MM,OFFSETS_X_MM,
OFFSETS_Y_MM,ANGLE)

(paper charts only)

Draw a symbol behind the text feature.

SYMBOL_NAME: name of the symbol drawn with the text.

SIZE_MM: size of the symbol in millimetres.

OFFSETS_X_MM: left/right offset for the symbol.

OFFSETS_Y_MM: downward/upward offset for the symbol.

ANGLE: the angle at which the symbol is drawn with respect to the text.
