Public Member Functions
virtual void SDK_CALLTYPE	Dump () const =0 throw ()
	Dumps given object.
virtual IGL2DCanvasSP SDK_CALLTYPE	GetParent () const =0 throw ()
	Returns parent canvas object.
virtual SDKSize SDK_CALLTYPE	GetSize () const =0 throw ()
	Returns texture dimensions.
virtual GL2DTextureFormat SDK_CALLTYPE	GetFormat () const =0 throw ()
	Returns texture format.
virtual GL2DNativeTextureFormat SDK_CALLTYPE	GetNativeFormat () const =0 throw ()
	Returns native (internal) texture format.
virtual bool SDK_CALLTYPE	IsPremultipliedColors () const =0 throw ()
	Returns pre-multiplied/non pre-multiplied colors flag.
virtual SDKUInt32 SDK_CALLTYPE	GetMemSize () const =0 throw ()
	Returns texture memory size.
virtual SDKInt32 SDK_CALLTYPE	GetID () const =0 throw ()
	Returns texture OpenGL ID.
virtual SDKResult SDK_CALLTYPE	GetBits (void *const data) const =0 throw ()
	Returns texture bits Bottom-left corner pixel color is a first byte, strides goes from bottom to top NOTE: Not all of textures support bits extraction due of it's format. Mostly it's about OpenGL ES2 and formats like BGRA/RGB/RGB16. At least for RGBA texture GetBits operation is always supported See IGL2DCaps::IsCanvasOperationSupported method VERY SLOW METHOD, USE FOR DEBUG PURPOSE ONLY!!!
virtual SDKResult SDK_CALLTYPE	Clone (IGL2DTextureSP &cloned_tex)=0 throw ()
	Clones given texture NOTE: Not all of textures can be cloned due of it's format. Mostly it's about OpenGL ES2 and formats like BGRA/RGB/RGB16. At least for RGBA texture cloning operation is always supported See IGL2DCaps::IsCanvasOperationSupported method.
virtual SDKResult SDK_CALLTYPE	CopyTo (const SDKRect2D &src_tex_rect, const SDKPointI2D &dst_pos, const IGL2DTextureSP &dst_tex)=0 throw ()
	Copies requested part of given texture to destination texture src_tex_rect - Describes rectangle of source (given) texture to copy (0, 0) - bottom left corner of given texture dst_pos - Destination position of bottom left corner of source texture in destination texture, (0,0) - bottom left corner of dest. tex. dst_tex - Destination texture, should have proper size to be able to fit source texture rectangle See IGL2DCaps::IsCanvasOperationSupported method.
SDKResult SDK_CALLTYPE	CopyTo (const SDKPointI2D &dst_pos, const IGL2DTextureSP &dst_tex)
	Copies whole source texture to destination texture.
virtual SDKResult SDK_CALLTYPE	SaveTexture (const SDKAny &file_path, const GL2DImageFormat &format) const =0 throw ()
	Saves given texture in requested format See IGL2DCanvasUtils::SaveTexture.
