getNumGlyphs

textNodeGetNumGlyphs :: (HasCallStack, MonadIO m, IsRenderNode a) => a -> m Word32 Source #

No description available in the introspection data.

getOffset

textNodeGetOffset Source #

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)
=> a	`node`: a text `RenderNode`
-> m Point	Returns: a point with the horizontal and vertical offsets

Retrieves the offset applied to the text.

new

textNodeNew Source #

Arguments

:: (HasCallStack, MonadIO m, IsFont a)
=> a	`font`: the `Font` containing the glyphs
-> GlyphString	`glyphs`: the `GlyphString` to render
-> RGBA	`color`: the foreground color to render with
-> Point	`offset`: offset of the baseline
-> m (Maybe TextNode)	Returns: a new `RenderNode`

Creates a render node that renders the given glyphs, Note that color may not be used if the font contains color glyphs.

peekColor

textNodePeekColor Source #

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)
=> a	`node`: a text `RenderNode`
-> m RGBA	Returns: the text color

Retrieves the color used by the text node.

peekFont

Arguments

:: (HasCallStack, MonadIO m, IsRenderNode a)
=> a	`node`: The `RenderNode`
-> m Font	Returns: the font

Returns the font used by the text node.

peekGlyphs

textNodePeekGlyphs Source #

Arguments

:: (HasCallStack, MonadIO m, IsTextNode a)
=> a	`node`: a text `RenderNode`
-> m [GlyphInfo]	Returns: the glyph information

Retrieves the glyph information in the node.
