Detailed Description

Texture class that is created by DirectfbRenderer objects.

Member Function Documentation

IDirectFBSurface* CEGUI::DirectfbTexture::getFBTexture ( void  ) const

inline

Return a pointer to the internal Directfb surface object.

Returns

Pointer to the Directfb surface object currently being used by this Texture object

virtual ushort CEGUI::DirectfbTexture::getHeight ( void  ) const

inlinevirtual

Returns the current pixel height of the texture.

Returns

ushort value that is the current height of the texture in pixels

Implements CEGUI::Texture.

virtual ushort CEGUI::DirectfbTexture::getWidth ( void  ) const

inlinevirtual

Returns the current pixel width of the texture.

Returns

ushort value that is the current width of the texture in pixels

Implements CEGUI::Texture.

void CEGUI::DirectfbTexture::loadFromFile ( const String &  filename, const String &  resourceGroup  )

virtual

Loads the specified image file into the texture. The texture is resized as required to hold the image.

Parameters

filename	The filename of the image file that is to be loaded into the texture
resourceGroup	Resource group identifier passed to the resource provider.

Returns

Nothing.

Implements CEGUI::Texture.

void CEGUI::DirectfbTexture::loadFromMemory ( const void *  buffPtr, uint  buffWidth, uint  buffHeight, Texture::PixelFormat  pixFormat  )

virtual

Loads (copies) an image in memory into the texture. The texture is resized as required to hold the image.

Parameters

buffPtr	Pointer to the buffer containing the image data
buffWidth	Width of the buffer (in pixels as specified by pixelFormat )
buffHeight	Height of the buffer (in pixels as specified by pixelFormat )
pixelFormat	PixelFormat value describing the format contained in buffPtr

Returns

Nothing.

Implements CEGUI::Texture.

void CEGUI::DirectfbTexture::setFBTextureSize

(

uint

size

)

set the size of the internal texture.

Parameters

size	pixel size of the new internal texture. This will be rounded up to a power of 2.

Returns

Nothing.
