Function getDataBlue

include/cinder/Surface.h:195–195

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

	const T*			getDataGreen( const ivec2 &offset ) const { return getData( offset ) + getGreenOffset(); }
	//! Returns a pointer to the blue channel data of the pixel located at \a offset. Result is a uint8_t* for Surface8u and a float* for Surface32f.
	T*					getDataBlue( const ivec2 &offset ) { return getData( offset ) + getBlueOffset(); }
	const T*			getDataBlue( const ivec2 &offset ) const { return getData( offset ) + getBlueOffset(); }
	//! Returns a pointer to the alpha channel data of the pixel located at \a offset. Result is a uint8_t* for Surface8u and a float* for Surface32f. Undefined for Surfaces without an alpha channel.
	T*					getDataAlpha( const ivec2 &offset ) { return getData( offset ) + getAlphaOffset(); }
