RGtk2 (version 2.20.31)

cairoGlyphExtents: cairoGlyphExtents

Description

Gets the extents for a list of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by cairoShowGlyphs). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by cairoShowGlyphs.

Usage

cairoGlyphExtents(cr, glyphs)

Arguments

cr
glyphs
[CairoGlyph] a list of CairoGlyph objects

Value

A list containing the following elements:
extents
[CairoTextExtents] a CairoTextExtents object into which the results will be stored

Details

Note that whitespace glyphs do not contribute to the size of the rectangle (extents.width and extents.height).
