Detailed Description

Texture implementation for the Direct3D9Renderer.

Member Function Documentation

void CEGUI::Direct3D9Texture::blitFromMemory	(	const void *	sourceData,
		const Rectf &	area
	)

virtual

Performs an area memory blit to the texture.

Parameters

sourceData	input data, the size must match area described by the given Rect
area	area where the blit will happen

Note: The pixel format must match current Texture's pixel format!

Implements CEGUI::Texture.

void CEGUI::Direct3D9Texture::blitToMemory ( void * targetData )

virtual

Performs a complete blit from the texture surface to memory.

Parameters

targetData the buffer where the target is stored

Note: You have to (correctly) preallocate the target buffer!

Implements CEGUI::Texture.

LPDIRECT3DTEXTURE9 CEGUI::Direct3D9Texture::getDirect3D9Texture ( ) const

Return the internal D3D9 texture used by this Texture object.

Returns: Pointer to the D3D9 texture interface that this object is using.

const String& CEGUI::Direct3D9Texture::getName ( ) const

virtual

Returns the name given to the texture when it was created.

Returns: Reference to a String object that holds the name of the texture.

Implements CEGUI::Texture.

const Sizef& CEGUI::Direct3D9Texture::getOriginalDataSize ( ) const

virtual

Returns the original pixel size of the data loaded into the texture.

Returns: reference to a Size object that describes the original size, in pixels, of the data loaded into the texture.

Implements CEGUI::Texture.

const Sizef& CEGUI::Direct3D9Texture::getSize ( ) const

virtual

Returns the current pixel size of the texture.

Returns: Reference to a Size object that describes the size of the texture in pixels.

Implements CEGUI::Texture.

const Vector2f& CEGUI::Direct3D9Texture::getTexelScaling ( ) const

virtual

Returns pixel to texel scale values that should be used for converting pixel values to texture co-ords.

Returns: Reference to a Vector2 object that describes the scaling values required to accurately map pixel positions to texture co-ordinates.

Implements CEGUI::Texture.

bool CEGUI::Direct3D9Texture::isPixelFormatSupported ( const PixelFormat fmt ) const

virtual

Return whether the specified pixel format is supported by the system for the CEGUI::Texture implementation.

The result of this call will vary according to the implementaion API
and the capabilities of the hardware.

Note: Whether the CEGUI system as a whole will make use of support for any given pixel format will depend upon that format being recognised and supported by both the renderer module implementation and the ImageCodec module that is used to load texture data.

Parameters

fmt	One of the PixelFormat enumerated values specifying the pixel format that is to be tested.

Returns

true if the specified PixelFormat is supported.
false if the specified PixelFormat is not supported.

Implements CEGUI::Texture.

void CEGUI::Direct3D9Texture::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 to be passed to the resource provider when loading the image file.

Returns: Nothing.

Implements CEGUI::Texture.

void CEGUI::Direct3D9Texture::loadFromMemory	(	const void *	buffer,
		const Sizef &	buffer_size,
		PixelFormat	pixel_format
	)

virtual

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

Parameters

buffer	Pointer to the buffer containing the image data.
buffer_size	Size of the buffer (in pixels as specified by pixelFormat)
pixel_format	PixelFormat value describing the format contained in buffPtr.

Returns: Nothing.

Implements CEGUI::Texture.

void CEGUI::Direct3D9Texture::setOriginalDataSize ( const Sizef & sz )

Sets what the texture should consider as the original data size.

Note: This also causes the texel scaling values to be updated.
