# Chapter 15. Geometric Objects

Partial Table-of-Contents

- 15.1 Text
- 15.2 Clipping
- 15.3 Path Operations

  The routines listed here create geometric Objects such as ribbons, tubes, glyphs, backgrounds, and geometric text. They are implemented by creating Field or Group Objects that can then be rendered.

  For detailed descriptions of these routines, see Appendix C. "Data Explorer Library Routines".

  ## 15.1 Text

  Data Explorer supports two varieties of text: geometric and annotation. Geometric text is implemented by stroke and area fonts that can be arbitrarily rotated and scaled before rendering. Annotation text is geometric text that has been transformed so that it always faces the screen. It is supported by a combination of a text routine listed below and the Screen Object described in Chapter 16. "Rendering".

  `Object DXGetFont()` | Returns a Group containing the specified font. See DXGetFont.
  `Object DXGeometricText()` | Produces an Object consisting of the given String. See DXGeometricText.
