Constructor Detail

AWTGVTGlyphVector

public AWTGVTGlyphVector(java.awt.font.GlyphVector glyphVector,
                         AWTGVTFont font,
                         double scaleFactor,
                         java.text.CharacterIterator ci)

Creates and new AWTGVTGlyphVector from the specified GlyphVector and AWTGVTFont objects.

Parameters:

glyphVector - The glyph vector that this one will be based upon.

font - The font that is creating this glyph vector.

scaleFactor - The scale factor to apply to the glyph vector. IMPORTANT: This is only required because the GlyphVector class doesn't handle font sizes less than 1 correctly. By using the scale factor we can use a GlyphVector created by a larger font and then scale it down to the correct size.

ci - The character string that this glyph vector represents.
