◆ CreateGfxDependentBitmap()

CGUIBitmapPlane * CGfxWrapOGLES2::CreateGfxDependentBitmap	(	GUIBitmapPlaneID_t	uiNewBitmapID,
		const CGUIObject &	rkParentObject,
		const eC_Value &	vWidth,
		const eC_Value &	vHeight
	)

protectedvirtual

Method which will be called by CreateBitmap to instantiate a new Bitmap-Object. This Method needs to be implemented by every derived GfxWrapper. If a GfxWrapper does not support Bitmap-Handling, he may create an CGUIBaseBitmap

See also: Bitmap planes

Parameters

uiNewBitmapID	ID of the new BitmapPlane
rkParentObject	reference to the GUIObject which will be the parent of the bitmap
vWidth	width of the new bitmap
vHeight	height of the new bitmap

Returns: pointer to the new created BitmapObject

Reimplemented from CGfxWrapGL.

◆ CreateInstance()

static eC_Bool CGfxWrapOGLES2::CreateInstance ( CGfxEnv * pkGfxEnv )

static

Singleton for creating a GfxWrapOGLES object and change the pointer in base class to this graphic wrap.

Parameters

pkGfxEnv environment to use

Returns: True if an instance was created by this call, otherwise False.

◆ ReadTextureData()

virtual void CGfxWrapOGLES2::ReadTextureData	(	const eC_UInt &	uiTexID,
		const eC_UInt &	uiXPos,
		const eC_UInt &	uiYPos,
		const eC_UInt &	uiWidth,
		const eC_UInt &	uiHeight,
		void *	pkData
	)

virtual

Read data from texture

Parameters

uiTexID
uiXPos
uiYPos
uiWidth
uiHeight
pkData

Implements CGfxWrapGL.
