Function getDataRed

include/cinder/Surface.h:189–189

Returns a pointer to the red channel data of the pixel located at \a offset. Result is a uint8_t* for Surface8u and a float* for Surface32f.

	const T*			getData( const ivec2 &offset ) const { return reinterpret_cast<T*>( reinterpret_cast<unsigned char*>( mData + offset.x * getPixelInc() ) + offset.y * mRowBytes ); }
	//! Returns a pointer to the red channel data of the pixel located at \a offset. Result is a uint8_t* for Surface8u and a float* for Surface32f.
	T*					getDataRed( const ivec2 &offset ) { return getData( offset ) + getRedOffset(); }
	const T*			getDataRed( const ivec2 &offset ) const { return getData( offset ) + getRedOffset(); }
	//! Returns a pointer to the green channel data of the pixel located at \a offset. Result is a uint8_t* for Surface8u and a float* for Surface32f.
	T*					getDataGreen( const ivec2 &offset ) { return getData( offset ) + getGreenOffset(); }
