Text Strings

igds_type: igds_text

Text string features correspond to IGDS element type 17. Normally, text strings are grouped together into a single complex element within MicroStation by text nodes. However, such text groups are handled in FME by the igds_multi_text type and not by this type, which is used only for single, free standing text strings. Text string features are point features, and only have a single coordinate.

Note that the V8 reader is capable of reading texts in Unicode (UTF-16) in Windows only.

Tip Some applications may use the graphic group field to logically group related text elements together.

Text strings have the following attributes:

Attribute Name	Notes	Contents
igds_original_justification		This attribute contains the original justification of the element when it was placed in the Design file. Once placed, all text elements are stored in the Design file using lower left corner (code 2) justification. Therefore, all text elements returned by the reader have an igds_justification of 2. The IDGS reader returns the original justification code in this attribute. The IGDS writer stores the value of this attribute in the justification bits of the placed text element, but it does NOT use its contents to determine placement of the text. Range: 0..12
igds_text_string	Reader only	The text string to be output. Text strings longer than 255 characters cannot be stored in a Design file and will be broken into multiple separate text elements. Range: Any string Default: No Default
igds_font	Reader only	The IGDS font number for the text string. Values from 0..511 are RSC fonts, while values from 512..1023 are SHX font, and values above 1023 are True Type fonts. Range: 0 Default: 25
igds_rotation	Reader only	The rotation of the text string. The rotation is measured in degrees counterclockwise up from horizontal. Range: -360.0..360.0 Default: 0
igds_justification		The justification code for the text string. See the Text Nodes section for documentation on the mapping of numbers to alignments. Note that if this is specified, the IGDS writer will compute the lower left corner of the text as best it can and use that when the element is written to the Design file. Text elements in a Design file are always stored using a lower left corner. The igds_original_justification may still be used in addition to this value, to override the justification bits of the placed text element. Range: 0..2,6..8, and 12..14 Default: 2
igds_text_size		The text size of the text, measured in ground units. This is stored as the height of the text element. Range: Any real number > 0 Default: 20
igds_text_width_multiplier		The text width of the text. The text width is measured in ground units. If this is not supplied, then igds_text_size is used. Range: Any real number > 0 Default: value of igds_text_size
igds_text_num_lines		If this is specified and is greater than 1, it will cause the text string to be broken into the number of lines specified, and output as that number of text elements stacked vertically. If this is not supplied, then igds_text_size is used. Range: Any integer > 0 Default: 1
igds_text_horizontal_flip		Indicates whether or not the text should be flipped horizontally when it is displayed. This is represented in a Design file by storing the text width as a negative number if the text should be flipped. (Not included in Version 8 DGN files.) Range: Yes\|No Default: No
igds_text_vertical_flip		Indicates whether or not the text should be flipped vertically when it is displayed. This is represented in a Design file by storing the text height as a negative number if the text should be flipped. (Not included in Version 8 DGN files.) Range: Yes\|No Default: No
igds_insertion_x igds_insertion_y igds_insertion_z	Reader only	The x, y, and z location of the original insertion point for the text, before the justification was applied. Range: Any real number > 0
igds_lower_x igds_lower_y igds_upper_x igds_upper_y	Reader only	The lower left and upper right x and y coordinates of the bounding box of the text. For text members of split text node elements, these bounds represent only those of the text member, while the more generic igds_xlow, etc. attributes represent the bounds of the overall text node element. Range: Any real number > 0
igds_textstyle_id		The ID of the textstyle being used. When writing, this ID may associate an existing text style definition in the seed file with this text element. If a matching ID is found, then that text style information is applied to this text element as the default style. Any text style specification for this text element on the feature as igds_textstyle_* attributes will take precedence over the matched default text style information. Default: None
igds_textstyle_bold		A flag indicating that the text should have a bold style. This takes precedence over the bold flag integrated into the igds_textstyle_exflags attribute. Default: None
igds_textstyle_char_spacing		Textstyle character spacing between characters. When writing, this is not used if an existing text style is found that has either inter-character spacing, fixed-width spacing, or AutoCAD-related spacing flags already set. Default: None
igds_textstyle_slant		This is the angle in degrees that the text slants, clockwise for horizontal, left-to-right text, as specified by the text style. This is a property which is part of the specification of italics. An angle of 30 degrees is usually used to apply an italic style. This takes precedence over the slanted flag integrated into the igds_textstyle_txflags attribute. Range: -180.0..180.0 Default: None
igds_textstyle_underline		A flag indicating that the text should have an underline style. This takes precedence over the underlined flag integrated into the igds_textstyle_txflags attribute. Default: None
igds_textstyle_underline_spacing		Textstyle underline spacing Default: None
igds_textstyle_underline_color		Textstyle underline color Default: None
igds_textstyle_underline_style		Textstyle underline style Default: None
igds_textstyle_underline_weight		Textstyle underline weight Default: None
igds_textstyle_overline		A flag indicating that the text should have an overline style. This takes precedence over the overlined flag integrated into the igds_textstyle_exflags attribute. Default: None
igds_textstyle_overline_spacing		Textstyle overline spacing Default: None
igds_textstyle_overline_color		Textstyle overline color Default: None
igds_textstyle_overline_style		Textstyle overline style Default: None
igds_textstyle_overline_weight		Textstyle overline weight Default: None
igds_textstyle_line_offset.x igds_textstyle_line_offset.y		Coordinates of textstyle line offset Default: None
igds_textstyle_codepage		Textstyle codepage. Specified as the integer portion of a Microsoft Windows code page, i.e., 1252 for Latin I. Default: None
igds_textstyle_bg_color		Textstyle background color Default: None
igds_textstyle_bg_style		Textstyle background style Default: None
igds_textstyle_bg_weight		Textstyle background weight Default: None
igds_textstyle_bg_border.x igds_textstyle_bg_border.y		Coordinates of textstyle background border Default: None
igds_textstyle_bg_fill_color		Textstyle background fill color Default: None
igds_textstyle_color		Textstyle color Default: None
igds_textstyle_font		Textstyle font Default: None
igds_textstyle_tnode_word_ wrap_len		Textstyle word wrap length Default: None
igds_textstyle_overrides_style1 igds_textstyle_overrides_style2		Textstyle override style flag Default: None
igds_textstyle_txflags		Textstyle flags. A reasonable setting to enable text style on write is 512. The bits of this integer value indicate the different text style properties to be applied to this text element. In general, these properties are specified by the other igds_textstyle_* attributes. If those attributes are set when writing a text element, the associated bits of this flag will automatically be set. For interpretation when reading, the following values are the base values for flags, which are added together to create the integer value of this attribute. inter-character spacing = 1 fixed-width spacing = 2 underlined = 4 slanted = 8 vertical= 16 right to left = 32 reversed multi-line = 64 kerning = 128 offset = 256 codepage = 512 shx big font = 1024 background color = 2048 subscript = 4096 superscript = 8192 extended text = 16384 text style = 32768 Range: Valid unsigned 16-bit integer Default: None
igds_textstyle_exflags		Textstyle extended flags are like igds_textstyle_txflags, but apply to extended textstyle properties. This attribute will be set from text styles during reading, and will be used to create text styles when writing. The bits of this integer value indicate the different text style properties to be applied to this text element. A limited number of these properties are specified by the other igds_textstyle_* attributes. If those attributes are set when writing a text element, the associated bits of this flag will automatically be set. For interpretation when reading, the following are some of the base values for flags, which are added together with other bits to create the integer value of this attribute. overlined = 1 bold = 65536 underline style = 131072 overline style = 262144 style overrides = 524288 word wrap text node = 1048576 color = 4194304 Range: Valid unsigned 32-bit integer Default: None

Note When a text string feature is reprojected, its rotation and text size are also automatically adjusted to be correct in the new coordinate system.

Note When writing textstyles, make sure that all the textstyles are added to the seed file being used.
