Method

PangoGlyphStringextents_range

Declaration [src]

void
pango_glyph_string_extents_range (
  PangoGlyphString* glyphs,
  int start,
  int end,
  PangoFont* font,
  PangoRectangle* ink_rect,
  PangoRectangle* logical_rect
)

Description [src]

Computes the extents of a sub-portion of a glyph string.

The extents are relative to the start of the glyph string range (the origin of their coordinate system is at the start of the range, not at the start of the entire glyph string).

Parameters

start

Type: int

Start index.

end

Type: int

End index (the range is the set of bytes with indices such that start <= index < end).

font

Type: PangoFont

A PangoFont.

The data is owned by the caller of the method.

ink_rect

Type: PangoRectangle

Rectangle used to store the extents of the glyph string range as drawn.

The argument will be set by the function.

The argument can be NULL.

The returned data is owned by the instance.

logical_rect

Type: PangoRectangle

Rectangle used to store the logical extents of the glyph string range.

The argument will be set by the function.

The argument can be NULL.

The returned data is owned by the instance.
