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.

◆ CodePoint

◆ CodePointRange

A range of code points, inclusive on both ends.

◆ UVRect

Member Enumeration Documentation

◆ LoadingFlags

Enum that allow to choose subset of unloaded/reloaded resources and to adjust reloading behavior.

Enumerator
LF_DEFAULT 

Only reloadable resources are processed, reload restores initial state.

LF_INCLUDE_NON_RELOADABLE 

Process non-reloadable resources too.

LF_ONLY_UNREFERENCED 

Process only resources which are not referenced by any other object. Usefull to reduce resource consumption.

LF_ONLY_UNREFERENCED_INCLUDE_NON_RELOADABLE 

Combination of LF_ONLY_UNREFERENCED and LF_INCLUDE_NON_RELOADABLE.

LF_PRESERVE_STATE 

Preserve some states during reloading, for example stencil shadows prepareness for Meshes.

LF_MARKED_FOR_RELOAD 

Resources are marked for reload on unloading, and only marked ones are processed on reloading.

◆ LoadingState

Enum identifying the loading state of the resource.

Enumerator
LOADSTATE_UNLOADED 

Not loaded.

LOADSTATE_LOADING 

Loading is in progress.

LOADSTATE_LOADED 

Fully loaded.

LOADSTATE_UNLOADING 

Currently unloading.

LOADSTATE_PREPARED 

Fully prepared.

LOADSTATE_PREPARING 

Preparing is in progress.

LOADSTATE_UNLOADED_MARKED_FOR_RELOAD 

Unloaded and marked for reload.

◆ Reason

Enumerator
Unknown 
FromStorageToSysRam 

OnStorage -> OnSystemRam.

FromSysRamToStorage 

OnSystemRam -> OnStorage.

GainedResidency 

OnStorage -> Resident OnSystemRam -> Resident See ReadyForRendering.

LostResidency 

Resident -> OnStorage Resident -> OnSystemRam.

PoolTextureSlotChanged 
ResidentToSysRamSync 

Only called while TextureGpu is still Resident, and strategy is AlwaysKeepSystemRamCopy.

This listener happens when something was done to the TextureGpu that modifies its contents in the GPU, and were thus forced to sync those values back to SystemRam. This listener calls tells that sync is over.

MetadataCacheOutOfDate 

The Metadata cache was out of date and we had to do a ping-pong.

Expect this to be followed by at least LostResidency and GainedResidency calls

This is very important, because if you were expecting certain sequence of calls (e.g. you were expecting a LostResidency soon to arrive), expect that to be changed.

See TextureGpuManager for details about the metadata cache.

ExceptionThrown 

Called when the worker thread caught an exception.

This exception has already been logged, and the texture resumed loading normally with a white 2x2 RGBA8 fallback.

This listener will get called from the main thread.

The texture may still have pending residency transitions (e.g. it may still be loading the 2x2 fallback)

Cast Exception e = reinterpret_cast<Exception>( extraData ); to know more info

FsaaSettingAlteredByApi 

Requested FSAA (MSAA / CSAA / EQAA / etc) is not supported by the API, and thus the setting had to be downgraded.

Note this may happen on device lost, and a new GPU became in use; thus it's possible for a TextureGpu to initially support certain FSAA but later change.

ReadyForRendering 

This Reason is called when TextureGpu::notifyDataIsReady is called.

This normally means worker thread is done loading texture from file and uploading it to GPU; and can now be used for rendering. It does NOT mean that Ogre has finished issueing rendering commands to a RenderTexture and is now ready to be presented to the monitor.

Member Function Documentation

◆ _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()

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

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
wasBackgroundLoadedWhether this was a background loaded event

◆ _firePreparingComplete()

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

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
wasBackgroundLoadedWhether this was a background loaded event

◆ _fireUnloadingComplete()

virtual void Ogre::Resource::_fireUnloadingComplete ( )
virtualinherited

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.

◆ _notifyOrigin()

virtual void Ogre::Resource::_notifyOrigin ( const String origin)
inlinevirtualinherited

Notify this resource of it's origin.

◆ 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.

◆ addListener()

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

Register a listener on this resource.

See also
Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ 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
newGroupName of the new group

◆ 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.

◆ clearCodePointRanges()

void Ogre::Font::clearCodePointRanges ( )
inline

Clear the list of code point ranges.

◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface dest) const
inlinevirtualinherited

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

References Ogre::StringInterface::setParameter().

◆ 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.

◆ getAntialiasColour()

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

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

◆ getCharacterSpacer()

uint Ogre::Font::getCharacterSpacer ( ) 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".

inlineinherited

◆ getParameter()

virtual String Ogre::StringInterface::getParameter ( const String name) const
inlinevirtualinherited

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
nameThe name of the parameter to get
Returns

References Ogre::ParamCommand::doGet().

◆ getParameters()

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

◆ getSize()

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

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ getSource()

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

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

◆ 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.

◆ 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.

◆ getTrueTypeResolution()

uint Ogre::Font::getTrueTypeResolution ( ) const

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

Remarks
Only applicable for FT_TRUETYPE Font objects.

◆ getTrueTypeSize()

Real Ogre::Font::getTrueTypeSize ( ) 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.

◆ getType()

FontType Ogre::Font::getType ( ) const

Gets the type of font.

◆ isBackgroundLoaded()

virtual bool Ogre::Resource::isBackgroundLoaded ( ) 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.

◆ isLoaded()

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

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

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

◆ 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 >::get().

◆ isManuallyLoaded()

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

Is this resource manually loaded?

◆ isPrepared()

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

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

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

◆ isReloadable()

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

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ 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
backgroundThreadIndicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

◆ markForReload()

bool Ogre::Resource::markForReload ( )
inlineinherited

◆ notifyTextureChanged()

void Ogre::Font::notifyTextureChanged ( TextureGpu texture,
TextureGpuListener::Reason  reason,
void *  extraData 
)
virtual

Called when a TextureGpu changed in a way that affects how it is displayed:

  1. TextureGpu::notifyDataIsReady got called (texture is ready to be displayed)
  2. Texture changed residency status.
  3. Texture is being deleted. It won't be a valid pointer after this call.

Implements Ogre::TextureGpuListener.

◆ 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
backgroundThreadWhether this is occurring in a background thread

◆ 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::UnifiedHighLevelGpuProgram, and Ogre::v1::Mesh.

◆ removeListener()

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

Remove a listener on this resource.

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.

◆ setBackgroundLoaded()

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

Tells the resource whether it is background loaded or not.

Remarks
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.

◆ setCharacterSpacer()

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

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

Parameters
charSpacerThe 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".

◆ 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.

◆ 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)

◆ setManuallyLoaded()

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

Set "Is this resource manually loaded?".

◆ setParameter()

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

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
nameThe name of the parameter to set
valueString 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)

◆ setParameterList()

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList paramList)
virtualinherited

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
paramListName/value pair list

◆ 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
sourceAn image file or a truetype font, depending on the type of this font

◆ setToLoaded()

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

Change the Resource loading state to loaded.

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

◆ 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
ttfResolutionThe resolution in dpi

◆ setTrueTypeSize()

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

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

Parameters
ttfSizeThe 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.

◆ setType()

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

Sets the type of font.

Must be set before loading.

◆ shouldStayLoaded()

virtual bool Ogre::TextureGpuListener::shouldStayLoaded ( TextureGpu texture)
inlinevirtualinherited

Return true if this TextureGpu should likely stay loaded or else graphical changes could occur.

Return false if it is certainly safe to unload.

Reimplemented in Ogre::VctLighting, and Ogre::OGRE_HLMS_TEXTURE_BASE_CLASS.

◆ touch()

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

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

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

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

◆ unload()

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

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.
