## 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

void Ogre::Font::createTextureFromFont | ( | void |  | ) | `[protected]`

Internal method for loading from ttf.

virtual void Ogre::Font::loadImpl | ( |  | ) | `[protected, virtual]`

Internal implementation of the meat of the 'load' action, only called if this resource is not being loaded from a ManualResourceLoader.

Implements Ogre::Resource.

virtual void Ogre::Font::unloadImpl | ( |  | ) | `[protected, virtual]`

Internal implementation of the 'unload' action; called regardless of whether this resource is being loaded from a ManualResourceLoader.

Implements Ogre::Resource.

size_t Ogre::Font::calculateSize | ( | void |  | ) | const`[protected, virtual]`

Calculate the size of a resource; this will only be called after 'load'.

Implements Ogre::Resource.

Definition at line 162 of file OgreFont.h.

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

Sets the type of font.

Must be set before loading.

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

Gets the type of font.

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

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

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

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.

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

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.

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.

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

Returns the teture 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

Definition at line 231 of file OgreFont.h.

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

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)

Definition at line 252 of file OgreFont.h.

References Ogre::TRect< T >::left.

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

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

Definition at line 273 of file OgreFont.h.

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

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.

Definition at line 290 of file OgreFont.h.

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;.

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

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.

Definition at line 312 of file OgreFont.h.

void Ogre::Font::clearCodePointRanges | ( |  | ) |

Clear the list of code point ranges.

Definition at line 319 of file OgreFont.h.

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

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

Definition at line 326 of file OgreFont.h.

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

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

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

Definition at line 334 of file OgreFont.h.

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

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

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

Definition at line 342 of file OgreFont.h.

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

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.

Definition at line 357 of file OgreFont.h.

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

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

Definition at line 365 of file OgreFont.h.

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.

virtual void Ogre::Resource::preLoadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions before the load process, but after the resource has been marked as 'loading'.

Note:
  Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Definition at line 149 of file OgreResource.h.

virtual void Ogre::Resource::postLoadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions after the load process, but before the resource has been marked as fully loaded.

Note:
  Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Reimplemented in Ogre::Mesh.

Definition at line 156 of file OgreResource.h.

virtual void Ogre::Resource::preUnloadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions before the unload process.

Note:
  Mutex will have already been acquired by the unloading thread.

Definition at line 161 of file OgreResource.h.

virtual void Ogre::Resource::postUnloadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions after the unload process, but before the resource has been marked as fully unloaded.

Note:
  Mutex will have already been acquired by the unloading thread.

Definition at line 166 of file OgreResource.h.

virtual void Ogre::Resource::queueFireBackgroundLoadingComplete | ( | void |  | ) | `[protected, virtual, inherited]`

Queue the firing of background loading complete event.

virtual void Ogre::Resource::load | ( | bool | backgroundThread = `false` | ) | `[virtual, inherited]`

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.

virtual void Ogre::Resource::reload | ( | void |  | ) | `[virtual, inherited]`

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.

bool Ogre::Resource::isReloadable | ( | void |  | ) | const`[inherited]`

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 228 of file OgreResource.h.

bool Ogre::Resource::isManuallyLoaded | ( | void |  | ) | const`[inherited]`

Is this resource manually loaded?

Definition at line 235 of file OgreResource.h.

virtual void Ogre::Resource::unload | ( | void |  | ) | `[virtual, inherited]`

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

size_t Ogre::Resource::getSize | ( | void |  | ) | const`[inherited]`

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 247 of file OgreResource.h.

virtual void Ogre::Resource::touch | ( | void |  | ) | `[virtual, inherited]`

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

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

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

const String& Ogre::Resource::getName | ( | void |  | ) | const`[inherited]`

Gets resource name.

Reimplemented in Ogre::SkeletonInstance.

Definition at line 258 of file OgreResource.h.

ResourceHandle Ogre::Resource::getHandle | ( | void |  | ) | const`[inherited]`

Reimplemented in Ogre::SkeletonInstance.

Definition at line 263 of file OgreResource.h.

bool Ogre::Resource::isLoaded | ( | void |  | ) | const`[inherited]`

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 270 of file OgreResource.h.

LoadingState Ogre::Resource::isLoading | ( |  | ) | const`[inherited]`

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

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 279 of file OgreResource.h.

LoadingState Ogre::Resource::getLoadingState | ( |  | ) | const`[inherited]`

Returns the current loading state.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 286 of file OgreResource.h.

bool Ogre::Resource::isBackgroundLoaded | ( | void |  | ) | const`[inherited]`

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.

Definition at line 303 of file OgreResource.h.

void Ogre::Resource::setBackgroundLoaded | ( | bool | bl | ) | `[inherited]`

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.

Definition at line 313 of file OgreResource.h.

void Ogre::Resource::escalateLoading | ( |  | ) | `[inherited]`

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.

void Ogre::Resource::addListener | ( | Listener * | lis | ) | `[inherited]`

Register a listener on this resource.

See also:
  Resource::Listener

void Ogre::Resource::removeListener | ( | Listener * | lis | ) | `[inherited]`

Remove a listener on this resource.

See also:
  Resource::Listener

const String& Ogre::Resource::getGroup | ( | void |  | ) | `[inherited]`

Gets the group which this resource is a member of.

Reimplemented in Ogre::SkeletonInstance.

Definition at line 337 of file OgreResource.h.

void Ogre::Resource::changeGroupOwnership | ( | const String & | newGroup | ) | `[inherited]`

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

ResourceManager* Ogre::Resource::getCreator | ( | void |  | ) | `[inherited]`

Gets the manager which created this resource.

Definition at line 349 of file OgreResource.h.

const String& Ogre::Resource::getOrigin | ( | void |  | ) | const`[inherited]`

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.

Definition at line 356 of file OgreResource.h.

void Ogre::Resource::_notifyOrigin | ( | const String & | origin | ) | `[inherited]`

Notify this resource of it's origin.

Definition at line 358 of file OgreResource.h.

virtual void Ogre::Resource::_fireBackgroundLoadingComplete | ( | void |  | ) | `[virtual, inherited]`

Firing of background 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.

bool Ogre::StringInterface::createParamDictionary | ( | const String & | className | ) | `[protected, inherited]`

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:
  This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

  | className | the name of the class using the dictionary

Returns:
  true if a new dictionary was created, false if it was already there

Definition at line 176 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | `[inherited]`

const ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | const`[inherited]`

Definition at line 213 of file OgreStringInterface.h.

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.

virtual bool Ogre::StringInterface::setParameter | ( | const String & | name,
|  | const String & | value |
| ) |  |  | `[virtual, 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:

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

virtual void Ogre::StringInterface::setParameterList | ( | const NameValuePairList & | paramList | ) | `[virtual, 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

virtual String Ogre::StringInterface::getParameter | ( | const String & | name | ) | const`[virtual, inherited]`

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

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const`[virtual, inherited]`

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.

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) | `[static, inherited]`

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.
