Remarks

A TrueTypeMarkerSymbol is used to display features with TrueType font characters. Any font installed on the Spatial Server machine may be used for the character. Note that if multiple machines are used as Spatial Servers, all must have the font installed.

To specify the character to use for the symbol, set the Font and the Character properties. The Font property describes which font on the system to use. The Character property specifies which character within the font to use for the symbol.

Tip: Use the Windows Character Map utility to explore and find the appropriate font and character. If the font displays standard Latin-style characters (i.e., a standard A-Z alphabet), you can simply use the character to define the Character value (see the Character property for examples). If the characters are symbols or a non-Latin alphabet, you will need to obtain its numeric value (decimal or hexadecimal), or find the Latin character equivalent. Click on the character you want to use to display the hexadecimal value in the status bar of Character Map. You can either use this value directly, or compare the position with a Latin-type character set to find the equivalent Latin character. See the Character property for example of converting this value to a usable value.

For ArcMap Server image services, valid only for acetate layers. ArcMap Server ignores several of the properties of this class. For details, see the topic for TRUETYPEMARKERSYMBOL in the ArcIMS Help, at ArcXML Guide - Symbol elements - TRUETYPEMARKERSYMBOL. The ArcIMS Help is also available online at ESRI).
