| context_get_resolution | Gets the resolution for the context. See context_set_resolution()
|
| context_set_font_options | Sets the font options used when rendering text with this context.
These options override any options that update_context()
derives from the target surface.
|
| context_set_resolution | Sets the resolution for the context. This is a scale factor between
points specified in a PangoFontDescription and Cairo units. The
default value is 96, meaning that a 10 point font will be 13
units high. (10 * 96. / 72. = 13.3).
|
| create_context | Creates a context object set up to match the current transformation
and target surface of the Cairo context. This context can then be
used to create a layout using pango::Layout::new().
|
| create_layout | Creates a layout object set up to match the current transformation
and target surface of the Cairo context. This layout can then be
used for text measurement with functions like
Layout::size() or drawing with functions like
show_layout(). If you change the transformation
or target surface for cr, you need to call update_layout()
|
| error_underline_path | Add a squiggly line to the current path in the specified cairo context that
approximately covers the given rectangle in the style of an underline used
to indicate a spelling error. (The width of the underline is rounded to an
integer number of up/down segments and the resulting rectangle is centered
in the original rectangle)
|
| glyph_string_path | Adds the glyphs in glyphs to the current path in the specified
cairo context. The origin of the glyphs (the left edge of the baseline)
will be at the current point of the cairo context.
|
| layout_line_path | Adds the text in pango::LayoutLine to the current path in the
specified cairo context. The origin of the glyphs (the left edge
of the line) will be at the current point of the cairo context.
|
| layout_path | Adds the text in a pango::Layout to the current path in the
specified cairo context. The top-left corner of the pango::Layout
will be at the current point of the cairo context.
|
| show_error_underline | Draw a squiggly line in the specified cairo context that approximately
covers the given rectangle in the style of an underline used to indicate a
spelling error. (The width of the underline is rounded to an integer
number of up/down segments and the resulting rectangle is centered in the
original rectangle)
|
| show_glyph_item | Draws the glyphs in glyph_item in the specified cairo context,
embedding the text associated with the glyphs in the output if the
output format supports it (PDF for example), otherwise it acts
similar to show_glyph_string().
|
| show_glyph_string | Draws the glyphs in glyphs in the specified cairo context.
The origin of the glyphs (the left edge of the baseline) will
be drawn at the current point of the cairo context.
|
| show_layout | Draws a pango::Layout in the specified cairo context.
The top-left corner of the pango::Layout will be drawn
at the current point of the cairo context.
|
| show_layout_line | Draws a pango::LayoutLine in the specified cairo context.
The origin of the glyphs (the left edge of the line) will
be drawn at the current point of the cairo context.
|
| update_context | Updates a pango::Context previously created for use with Cairo to
match the current transformation and target surface of a Cairo
context. If any layouts have been created for the context,
it’s necessary to call Layout::context_changed() on those
layouts.
|
| update_layout | Updates the private pango::Context of a pango::Layout created with
create_layout() to match the current transformation
and target surface of a Cairo context.
