CPixelView< PIXEL_TYPE > Class Template Reference

Detailed Description

template<class PIXEL_TYPE>
class CPixelView< PIXEL_TYPE >

Represents a set of LED objects.

Provides the [] array operator, and works like a normal array in that case. This should be kept in sync with the set of functions provided by the other Pixel Data Types (CRGB/CHSV) as well as functions in colorutils.h.

Template Parameters

PIXEL_TYPE

the type of LED data referenced in the class, e.g. CRGB.

Note

A pixel set is a window into another set of LED data, it is not its own set of LED data.

Apply the PIXEL_TYPE |= operator to every pixel in this set with every pixel in the passed in set.

With CRGB, this brings up each channel to the higher of the two values

operator|=() [2/3]

template<class PIXEL_TYPE >

CPixelView & CPixelView< PIXEL_TYPE >::operator|= ( const PIXEL_TYPE & rhs )

inline

Apply the PIXEL_TYPE |= operator to every pixel in this set with the given PIXEL_TYPE value.

With CRGB, this brings up each channel to the higher of the two values

operator|=() [3/3]

template<class PIXEL_TYPE >

CPixelView & CPixelView< PIXEL_TYPE >::operator|= ( uint8_t d )

inline

Apply the PIXEL_TYPE |= operator to every pixel in this set.

With CRGB, this brings up each channel to the higher of the two values

reversed()

template<class PIXEL_TYPE >

bool CPixelView< PIXEL_TYPE >::reversed ( )

inline

Whether or not this set goes backwards.

Returns

whether or not the set is backwards

Definition at line 96 of file pixelset.h.

size()

template<class PIXEL_TYPE >

int CPixelView< PIXEL_TYPE >::size ( )

inline

Get the size of this set.

Returns

the size of the set, in number of LEDs

Definition at line 92 of file pixelset.h.

subFromRGB()

template<class PIXEL_TYPE >

CPixelView & CPixelView< PIXEL_TYPE >::subFromRGB ( uint8_t inc )

inline

Subtract the passed in value from all channels for all of the pixels in this set.

Definition at line 161 of file pixelset.h.

Member Data Documentation

dir

template<class PIXEL_TYPE >

const int8_t CPixelView< PIXEL_TYPE >::dir

direction of the LED data, either 1 or -1. Determines how the pointer is incremented.

Definition at line 67 of file pixelset.h.

end_pos

template<class PIXEL_TYPE >

PIXEL_TYPE* const CPixelView< PIXEL_TYPE >::end_pos

pointer to the end position of the LED data

Definition at line 71 of file pixelset.h.

leds

template<class PIXEL_TYPE >

PIXEL_TYPE* const CPixelView< PIXEL_TYPE >::leds

pointer to the LED data

Definition at line 70 of file pixelset.h.

len

template<class PIXEL_TYPE >

const int CPixelView< PIXEL_TYPE >::len

length of the LED data, in PIXEL_TYPE units.

More accurately, it's the distance from the start of the CPixelView::leds array to the end of the set (CPixelView::end_pos)

Definition at line 68 of file pixelset.h.
