Retrieves the color used by the text node.

getFont

textNodeGetFont

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)

=> a

node: The GskRenderNode

-> m Font

Returns: the font

Returns the font used by the text node.

getGlyphs

textNodeGetGlyphs

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)

=> a

node: a text GskRenderNode

Returns: the glyph information

Retrieves the glyph information in the node.

getNumGlyphs

textNodeGetNumGlyphs

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)

=> a

node: a text GskRenderNode

-> m Word32

Returns: the number of glyphs

Retrieves the number of glyphs in the text node.

getOffset

textNodeGetOffset

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)

=> a

node: a text GskRenderNode

-> m Point

Returns: a point with the horizontal and vertical offsets

Retrieves the offset applied to the text.

hasColorGlyphs

textNodeHasColorGlyphs

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)

=> a

node: a text GskRenderNode

-> m Bool

Returns: True if the text node has color glyphs

Checks whether the text node has color glyphs.

new

textNodeNew

Arguments

:: (HasCallStack, MonadIO m, IsFont a)

=> a

font: the PangoFont containing the glyphs

-> GlyphString

glyphs: the PangoGlyphString to render

-> RGBA

color: the foreground color to render with

-> Point

offset: offset of the baseline

-> m (Maybe TextNode)

Returns: a new GskRenderNode

Creates a render node that renders the given glyphs.

Note that color may not be used if the font contains color glyphs.
