Detailed Description

Class representing a font in the system.

Remarks: This class is simply a way of getting a font texture into the OGRE system and to easily retrieve the texture coordinates required to accurately render them. Fonts can either be loaded from precreated textures, or the texture can be generated using a truetype font. You can either create the texture manually in code, or you can use a .fontdef script to define it (probably more practical since you can reuse the definition more easily)

Note: This class extends both Resource and ManualResourceLoader since it is both a resource in it's own right, but it also provides the manual load implementation for the Texture it creates.

Member Function Documentation

◆ setType()

void Ogre::Font::setType ( FontType ftype )

Sets the type of font.

Must be set before loading.

◆ getType()

FontType Ogre::Font::getType ( void ) const

Gets the type of font.

◆ setSource()

void Ogre::Font::setSource ( const String & source )

Sets the source of the font.

Remarks: If you have created a font of type FT_IMAGE, this method tells the Font which image to use as the source for the characters. So the parameter should be the name of an appropriate image file. Note that when using an image as a font source, you will also need to tell the font where each character is located using setGlyphTexCoords (for each character).

: If you have created a font of type FT_TRUETYPE, this method tells the Font which .ttf file to use to generate the text. You will also need to call setTrueTypeSize and setTrueTypeResolution, and call addCodePointRange as many times as required to define the range of glyphs you want to be available.

Parameters

source An image file or a truetype font, depending on the type of this font

◆ getSource()

const String& Ogre::Font::getSource ( void ) const

Gets the source this font (either an image or a truetype font).

◆ setCharacterSpacer()

void Ogre::Font::setCharacterSpacer ( uint charSpacer )

Sets the spacing to allocate for font characters to overlap each other.

Parameters

charSpacer The size of the character spacer, in points. Increasing it allows for more stretched-out fonts; decreasing it reduces memory and processing time. The default is "5".

◆ getCharacterSpacer()

uint Ogre::Font::getCharacterSpacer ( void ) const

Gets the spacing to allocate for font characters to overlap each other.

Remarks: Returns the size of the character spacer, in points. A higher value allows for more stretched-out fonts. A low value reduces memory and processing time. The default is "5".

◆ setTrueTypeSize()

void Ogre::Font::setTrueTypeSize ( Real ttfSize )

Sets the size of a truetype font (only required for FT_TRUETYPE).

Parameters

ttfSize The size of the font in points. Note that the size of the font does not affect how big it is on the screen, just how large it is in the texture and thus how detailed it is.

◆ setTrueTypeResolution()

void Ogre::Font::setTrueTypeResolution ( uint ttfResolution )

Gets the resolution (dpi) of the font used to generate the texture (only required for FT_TRUETYPE).

Parameters

ttfResolution The resolution in dpi

◆ getTrueTypeSize()

Real Ogre::Font::getTrueTypeSize ( void ) const

Gets the point size of the font used to generate the texture.

Remarks: Only applicable for FT_TRUETYPE Font objects. Note that the size of the font does not affect how big it is on the screen, just how large it is in the texture and thus how detailed it is.

◆ getTrueTypeResolution()

uint Ogre::Font::getTrueTypeResolution ( void ) const

Gets the resolution (dpi) of the font used to generate the texture.

Remarks: Only applicable for FT_TRUETYPE Font objects.

◆ getTrueTypeMaxBearingY()

int Ogre::Font::getTrueTypeMaxBearingY ( ) const

Gets the maximum baseline distance of all glyphs used in the texture.

Remarks: Only applicable for FT_TRUETYPE Font objects. The baseline is the vertical origin of horizontal based glyphs. The bearingY attribute is the distance from the baseline (origin) to the top of the glyph's bounding box.

Note: This value is only available after the font has been loaded.

◆ getGlyphTexCoords()

const UVRect& Ogre::Font::getGlyphTexCoords ( CodePoint id ) const

inline

Returns the texture coordinates of the associated glyph.

Remarks: Parameter is a short to allow both ASCII and wide chars.

Parameters

id	The code point (unicode)

Returns: A rectangle with the UV coordinates, or null UVs if the code point was not present

◆ setGlyphTexCoords()

void Ogre::Font::setGlyphTexCoords	(	CodePoint	id,
		Real	u1,
		Real	v1,
		Real	u2,
		Real	v2,
		Real	textureAspect
	)

inline

Sets the texture coordinates of a glyph.

Remarks: You only need to call this if you're setting up a font loaded from a texture manually.

Note: Also sets the aspect ratio (width / height) of this character. textureAspect is the width/height of the texture (may be non-square)

◆ getGlyphAspectRatio()

Real Ogre::Font::getGlyphAspectRatio ( CodePoint id ) const

inline

Gets the aspect ratio (width / height) of this character.

◆ setGlyphAspectRatio()

void Ogre::Font::setGlyphAspectRatio	(	CodePoint	id,
		Real	ratio
	)

inline

Sets the aspect ratio (width / height) of this character.

Remarks: You only need to call this if you're setting up a font loaded from a texture manually.

◆ getGlyphInfo()

const GlyphInfo& Ogre::Font::getGlyphInfo ( CodePoint id ) const

Gets the information available for a glyph corresponding to a given code point, or throws an exception if it doesn't exist;.

◆ addCodePointRange()

void Ogre::Font::addCodePointRange ( const CodePointRange & range )

inline

Adds a range of code points to the list of code point ranges to generate glyphs for, if this is a truetype based font.

Remarks: In order to save texture space, only the glyphs which are actually needed by the application are generated into the texture. Before this object is loaded you must call this method as many times as necessary to define the code point range that you need.

◆ clearCodePointRanges()

void Ogre::Font::clearCodePointRanges ( )

inline

Clear the list of code point ranges.

◆ getCodePointRangeList()

const CodePointRangeList& Ogre::Font::getCodePointRangeList ( ) const

inline

Get a const reference to the list of code point ranges to be used to generate glyphs from a truetype font.

◆ getMaterial() [1/2]

const MaterialPtr& Ogre::Font::getMaterial ( ) const

inline

Gets the material generated for this font, as a weak reference.

Remarks: This will only be valid after the Font has been loaded.

◆ getMaterial() [2/2]

const MaterialPtr& Ogre::Font::getMaterial ( )

inline

Gets the material generated for this font, as a weak reference.

Remarks: This will only be valid after the Font has been loaded.

◆ setAntialiasColour()

void Ogre::Font::setAntialiasColour ( bool enabled )

inline

Sets whether or not the colour of this font is antialiased as it is generated from a true type font.

Remarks: This is valid only for a FT_TRUETYPE font. If you are planning on using alpha blending to draw your font, then it is a good idea to set this to false (which is the default), otherwise the darkening of the font will combine with the fading out of the alpha around the edges and make your font look thinner than it should. However, if you intend to blend your font using a colour blending mode (add or modulate for example) then it's a good idea to set this to true, in order to soften your font edges.

◆ getAntialiasColour()

bool Ogre::Font::getAntialiasColour ( void ) const

inline

Gets whether or not the colour of this font is antialiased as it is generated from a true type font.

◆ loadResource()

void Ogre::Font::loadResource ( Resource * resource )

virtual

Implementation of ManualResourceLoader::loadResource, called when the Texture that this font creates needs to (re)load.

Implements Ogre::ManualResourceLoader.

◆ prepare()

virtual void Ogre::Resource::prepare ( bool backgroundThread = false )

virtualinherited

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters

backgroundThread Whether this is occurring in a background thread

◆ load()

virtual void Ogre::Resource::load ( bool backgroundThread = false )

virtualinherited

Loads the resource, if it is not already.

Remarks: If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Parameters

backgroundThread Indicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ reload()

virtual void Ogre::Resource::reload ( LoadingFlags flags = LF_DEFAULT )

virtualinherited

Reloads the resource, if it is already loaded.

Remarks: Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::Mesh, and Ogre::UnifiedHighLevelGpuProgram.

◆ isReloadable()

virtual bool Ogre::Resource::isReloadable ( void ) const

inlinevirtualinherited

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ isManuallyLoaded()

virtual bool Ogre::Resource::isManuallyLoaded ( void ) const

inlinevirtualinherited

Is this resource manually loaded?

◆ setManuallyLoaded()

virtual void Ogre::Resource::setManuallyLoaded ( bool isManual )

inlinevirtualinherited

Set "Is this resource manually loaded?".

Deprecated:: do not use

◆ unload()

virtual void Ogre::Resource::unload ( void )

virtualinherited

Unloads the resource; this is not permanent, the resource can be reloaded later if required.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ getSize()

virtual size_t Ogre::Resource::getSize ( void ) const

inlinevirtualinherited

Retrieves info about the size of the resource.

Reimplemented in Ogre::CgProgram, and Ogre::UnifiedHighLevelGpuProgram.

◆ touch()

virtual void Ogre::Resource::touch ( void )

virtualinherited

'Touches' the resource to indicate it has been used.

Reimplemented in Ogre::Material, Ogre::CgProgram, and Ogre::UnifiedHighLevelGpuProgram.

Referenced by Ogre::Material::touch().

◆ getName()

virtual const String& Ogre::Resource::getName ( void ) const

inlinevirtualinherited

Gets resource name.

Reimplemented in Ogre::SkeletonInstance.

Referenced by Ogre::GpuProgramUsage::getProgramName(), and OgreBites::TrayManager::resourceLoadStarted().

◆ getHandle()

virtual ResourceHandle Ogre::Resource::getHandle ( void ) const

inlinevirtualinherited

Reimplemented in Ogre::SkeletonInstance.

◆ isPrepared()

virtual bool Ogre::Resource::isPrepared ( void ) const

inlinevirtualinherited

Returns true if the Resource has been prepared, false otherwise.

References Ogre::AtomicScalar< T >::load().

◆ isLoaded()

virtual bool Ogre::Resource::isLoaded ( void ) const

inlinevirtualinherited

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

References Ogre::AtomicScalar< T >::load().

◆ setToLoaded()

virtual void Ogre::Resource::setToLoaded ( void )

inlinevirtualinherited

Change the Resource loading state to loaded.

Deprecated:: do not use

References Ogre::AtomicScalar< T >::store().

◆ isLoading()

virtual bool Ogre::Resource::isLoading ( ) const

inlinevirtualinherited

Returns whether the resource is currently in the process of background loading.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

References Ogre::AtomicScalar< T >::load().

◆ getLoadingState()

virtual LoadingState Ogre::Resource::getLoadingState ( ) const

inlinevirtualinherited

Returns the current loading state.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

References Ogre::AtomicScalar< T >::load().

◆ isBackgroundLoaded()

virtual bool Ogre::Resource::isBackgroundLoaded ( void ) const

inlinevirtualinherited

Returns whether this Resource has been earmarked for background loading.

Remarks: This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ setBackgroundLoaded()

virtual void Ogre::Resource::setBackgroundLoaded ( bool bl )

inlinevirtualinherited

Tells the resource whether it is background loaded or not.

See also: Resource::isBackgroundLoaded. Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ escalateLoading()

virtual void Ogre::Resource::escalateLoading ( )

virtualinherited

Escalates the loading of a background loaded resource.

Remarks: If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ addListener()

virtual void Ogre::Resource::addListener ( Listener * lis )

virtualinherited

Register a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ removeListener()

virtual void Ogre::Resource::removeListener ( Listener * lis )

virtualinherited

Remove a listener on this resource.

See also: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ getGroup()

virtual const String& Ogre::Resource::getGroup ( void ) const

inlinevirtualinherited

Gets the group which this resource is a member of.

Reimplemented in Ogre::SkeletonInstance.

◆ changeGroupOwnership()

virtual void Ogre::Resource::changeGroupOwnership ( const String & newGroup )

virtualinherited

Change the resource group ownership of a Resource.

Remarks: This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters

newGroup Name of the new group

◆ getCreator()

ResourceManager* Ogre::Resource::getCreator ( void )

inlineinherited

Gets the manager which created this resource.

◆ getOrigin()

const String& Ogre::Resource::getOrigin ( void ) const

inlineinherited

Get the origin of this resource, e.g.

a script file name.

Remarks: This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

◆ _notifyOrigin()

void Ogre::Resource::_notifyOrigin ( const String & origin )

inlineinherited

Notify this resource of it's origin.

◆ getStateCount()

virtual size_t Ogre::Resource::getStateCount ( ) const

inlinevirtualinherited

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

◆ _dirtyState()

virtual void Ogre::Resource::_dirtyState ( )

virtualinherited

Manually mark the state of this resource as having been changed.

Remarks: You only need to call this from outside if you explicitly want derived objects to think this object has changed.

See also: getStateCount.

◆ _fireLoadingComplete()

void Ogre::Resource::_fireLoadingComplete ( bool wasBackgroundLoaded )

inherited

Firing of loading complete event.

Remarks: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

wasBackgroundLoaded Whether this was a background loaded event

◆ _firePreparingComplete()

void Ogre::Resource::_firePreparingComplete ( bool wasBackgroundLoaded )

inherited

Firing of preparing complete event.

Remarks: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

wasBackgroundLoaded Whether this was a background loaded event

◆ _fireUnloadingComplete()

void Ogre::Resource::_fireUnloadingComplete ( void )

inherited

Firing of unloading complete event.

Remarks: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

◆ getParamDictionary() [1/2]

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void )

inlineinherited

Retrieves the parameter dictionary for this class.

Remarks: Only valid to call this after createParamDictionary.

Returns: Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

◆ getParamDictionary() [2/2]

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) const

inlineinherited

◆ getParameters()

const ParameterList& Ogre::StringInterface::getParameters ( void ) const

inherited

Retrieves a list of parameters valid for this object.

Returns: A reference to a static list of ParameterDef objects.

◆ setParameter()

bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)

inherited

Generic parameter setting method.

Remarks: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

name	The name of the parameter to set
value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

◆ setParameterList()

void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList )

inherited

Generic multiple parameter setting method.

Remarks: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

paramList Name/value pair list

◆ getParameter()

String Ogre::StringInterface::getParameter ( const String & name ) const

inlineinherited

Generic parameter retrieval method.

Remarks: Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters

name	The name of the parameter to get

Returns: String value of parameter, blank if not found

References Ogre::ParamCommand::doGet().

◆ copyParametersTo()

void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const

inlineinherited

Method for copying this object's parameters to another object.

Remarks: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters

dest	Pointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )

staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

◆ prepareResource()

virtual void Ogre::ManualResourceLoader::prepareResource ( Resource * resource )

inlinevirtualinherited

Called when a resource wishes to load.

Note that this could get called in a background thread even in just a semithreaded ogre (OGRE_THREAD_SUPPORT==2). Thus, you must not access the rendersystem from this callback. Do that stuff in loadResource.

Parameters

resource The resource which wishes to load
