GI.CoglPango.Functions

Methods

ensureGlyphCacheForLayout

ensureGlyphCacheForLayout

Arguments

:: (HasCallStack, MonadIO m, IsLayout a)

=> a

layout: A Layout

-> m ()

This updates any internal glyph cache textures as necessary to be able to render the given layout.

This api should be used to avoid mid-scene modifications of glyph-cache textures which can lead to undefined rendering results.

Since: 1.0

fontMapClearGlyphCache

fontMapClearGlyphCache

Arguments

:: (HasCallStack, MonadIO m, IsFontMap a)

=> a

fontMap: a CoglPangoFontMap

-> m ()

Clears the glyph cache for fontMap.

Since: 1.0

fontMapCreateContext

fontMapCreateContext

Arguments

:: (HasCallStack, MonadIO m, IsFontMap a)

=> a

fontMap: a CoglPangoFontMap

-> m Context

Returns: the newly created context: free with objectUnref.

Create a Context for the given fontMap.

fontMapGetRenderer

fontMapGetRenderer

Arguments

:: (HasCallStack, MonadIO m, IsFontMap a)

=> a

fontMap: a CoglPangoFontMap

-> m Renderer

Returns: a Renderer

Retrieves the Renderer for the passed fontMap.

Since: 1.0

fontMapGetUseMipmapping

fontMapGetUseMipmapping

Arguments

:: (HasCallStack, MonadIO m, IsFontMap a)

=> a

fontMap: a CoglPangoFontMap

-> m Int32

Returns: True if mipmapping is used, False otherwise.

Retrieves whether the Renderer used by fontMap will use mipmapping when rendering the glyphs.

Since: 1.0

fontMapNew

fontMapNew

Arguments

:: (HasCallStack, MonadIO m)

=> m FontMap

Returns: the newly created FontMap

Creates a new font map.

Since: 1.14

fontMapSetResolution

fontMapSetResolution

Arguments

:: (HasCallStack, MonadIO m, IsFontMap a)

=> a

fontMap: a CoglPangoFontMap

-> Double

dpi: The resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.)

-> m ()

Sets the resolution for the fontMap. This is a scale factor between points specified in a FontDescription and Cogl units. The default value is 96, meaning that a 10 point font will be 13 units high. (10 * 96. / 72. = 13.3).

Since: 1.14

fontMapSetUseMipmapping

fontMapSetUseMipmapping

Arguments

:: (HasCallStack, MonadIO m, IsFontMap a)

=> a

fontMap: a CoglPangoFontMap

-> Int32

value: True to enable the use of mipmapping

-> m ()

Sets whether the renderer for the passed font map should use mipmapping when rendering a Layout.

Since: 1.0

renderLayout

renderLayout

Arguments

:: (HasCallStack, MonadIO m, IsLayout a)

=> a

layout: a Layout

-> Int32

x: X coordinate to render the layout at

-> Int32

y: Y coordinate to render the layout at

-> Color

color: color to use when rendering the layout

-> Int32

-> m ()

Deprecated: (Since version 1.16)Use cogl_pango_show_layout() instead

Draws a solidly coloured layout on the given framebuffer at (x, y) within the framebuffer's current model-view coordinate space.

Since: 1.0

renderLayoutLine

renderLayoutLine

Arguments

:: (HasCallStack, MonadIO m)

=> LayoutLine

line: a LayoutLine

-> Int32

x: X coordinate to render the line at

-> Int32

y: Y coordinate to render the line at

-> Color

color: color to use when rendering the line

-> m ()

Deprecated: (Since version 1.16)Use cogl_pango_show_layout() instead

Renders line at the given coordinates using the given color.

Since: 1.0

renderLayoutSubpixel

renderLayoutSubpixel

Arguments

:: (HasCallStack, MonadIO m, IsLayout a)

=> a

layout: a Layout

-> Int32

x: X coordinate (in Pango units) to render the layout at

-> Int32

y: Y coordinate (in Pango units) to render the layout at

-> Color

color: color to use when rendering the layout

-> Int32

-> m ()

Deprecated: (Since version 1.16)Use cogl_pango_show_layout() instead

Draws a solidly coloured layout on the given framebuffer at (x, y) within the framebuffer's current model-view coordinate space.
