Detailed Description

Class providing a shared library of Font objects to the system.

The FontManager is used to create, access, and destroy Font objects. The idea is that the FontManager will function as a central repository for Font objects used within the GUI system, and that those Font objects can be accessed, via a unique name, by any interested party within the system.

Member Function Documentation

Font& CEGUI::FontManager::createFreeTypeFont ( const String font_name,
const float  point_size,
const bool  anti_aliased,
const String font_filename,
const String resource_group = "",
const AutoScaledMode  auto_scaled = ASM_Disabled,
const Sizef native_res = Sizef(640.0f, 480.0f),
XMLResourceExistsAction  action = XREA_RETURN 
)

Creates a FreeType type font.

Parameters
font_nameThe name that the font will use within the CEGUI system.
point_sizeSpecifies the point size that the font is to be rendered at.
anti_aliasedSpecifies whether the font should be rendered using anti aliasing.
font_filenameThe filename of an font file that will be used as the source for glyph images for this font.
resource_groupThe resource group identifier to use when loading the font file specified by font_filename.
auto_scaledSpecifies whether the font imagery should be automatically scaled to maintain the same physical size (which is calculated by using the native resolution setting).
native_horz_resThe horizontal native resolution value. This is only significant when auto scaling is enabled.
native_vert_resThe vertical native resolution value. This is only significant when auto scaling is enabled.
actionOne of the XMLResourceExistsAction enumerated values indicating what action should be taken when a Font with the specified name already exists.
Returns
Reference to the newly create Font object.
Font& CEGUI::FontManager::createPixmapFont ( const String font_name,
const String imageset_filename,
const String resource_group = "",
const AutoScaledMode  auto_scaled = ASM_Disabled,
const Sizef native_res = Sizef(640.0f, 480.0f),
XMLResourceExistsAction  action = XREA_RETURN 
)

Creates a Pixmap type font.

Parameters
font_nameThe name that the font will use within the CEGUI system.
imageset_filenameThe filename of an imageset to load that will be used as the source for glyph images for this font. If resource_group is the special value of "*", this parameter may instead refer to the name of an already loaded Imagset.
resource_groupThe resource group identifier to use when loading the imageset file specified by imageset_filename. If this group is set to the special value of "*", then imageset_filename instead will refer to the name of an existing Imageset.
auto_scaledSpecifies whether the font imagery should be automatically scaled to maintain the same physical size (which is calculated by using the native resolution setting).
native_horz_resThe horizontal native resolution value. This is only significant when auto scaling is enabled.
native_vert_resThe vertical native resolution value. This is only significant when auto scaling is enabled.
actionOne of the XMLResourceExistsAction enumerated values indicating what action should be taken when a Font with the specified name already exists.
Returns
Reference to the newly create Font object.
void CEGUI::FontManager::notifyDisplaySizeChanged ( const Sizef size)

Notify the FontManager that display size may have changed.

Parameters
sizeSize object describing the display resolution
void CEGUI::FontManager::writeFontToStream ( const String name,
OutStream out_stream 
) const

Writes a full XML font file for the specified Font to the given OutStream.

Parameters
nameString holding the name of the Font to be written to the stream.
out_streamOutStream (std::ostream based) object where data is to be sent.
