Detailed Description

The ImageProcessor translates an RGB-image to RGB-values for the leds.

The processing is performed in two steps. First the average color per led-region is computed. Second a color-tranform is applied based on a gamma-correction.

Constructor & Destructor Documentation

ImageProcessor()

ImageProcessor::ImageProcessor	(	const LedString &	ledString,
		Hyperion *	hyperion
	)

Constructs an image-processor for translating an image to led-color values based on the given led-string specification.

Parameters

[in]	ledString	LedString data
[in]	hyperion	Hyperion instance pointer

Member Function Documentation

getScanParameters()

bool ImageProcessor::getScanParameters	(	size_t	led,
		double &	hscanBegin,
		double &	hscanEnd,
		double &	vscanBegin,
		double &	vscanEnd
	)		const

Get the hscan and vscan parameters for a single led.

Parameters

[in]	led	Index of the led
[out]	hscanBegin	begin of the hscan
[out]	hscanEnd	end of the hscan
[out]	vscanBegin	begin of the hscan
[out]	vscanEnd	end of the hscan

Returns

true if the parameters could be retrieved

process() [1/2]

template<typename Pixel_T >

std::vector<ColorRgb> ImageProcessor::process ( const Image< Pixel_T > &  image )

inline

Processes the image to a list of led colors.

This will update the size of the buffer-image if required and call the image-to-leds mapping to determine the mean color per led.

Parameters

[in]

image

The image to translate to led values

Returns

The color value per led

process() [2/2]

template<typename Pixel_T >

void ImageProcessor::process ( const Image< Pixel_T > &  image, std::vector< ColorRgb > &  ledColors  )

inline

Determines the led colors of the image in the buffer.

Parameters

[in]	image	The image to translate to led values
[out]	ledColors	The color value per led

setHardLedMappingType()

void ImageProcessor::setHardLedMappingType

(

int

mapType

)

Set the Hyperion::update() requestes led mapping type.

This type is used in favour of type set with setLedMappingType. If you don't want to force a mapType set this to -1 (user choice will be set)

Parameters

mapType

The new mapping type

setLedMappingType

void ImageProcessor::setLedMappingType ( int  mapType )

slot

Set the user requested led mapping.

The type set with setHardLedMappingType() will be used in favour to respect comp specific settings

Parameters

mapType

The new mapping type

setSize() [1/2]

void ImageProcessor::setSize	(	const unsigned	width,
		const unsigned	height
	)

Specifies the width and height of 'incomming' images.

This will resize the buffer-image to match the given size. NB All earlier obtained references will be invalid.

Parameters

[in]	width	The new width of the buffer-image
[in]	height	The new height of the buffer-image

setSize() [2/2]

template<typename Pixel_T >

void ImageProcessor::setSize ( const Image< Pixel_T > &  image )

inline

Specifies the width and height of 'incomming' images.

This will resize the buffer-image to match the given size. NB All earlier obtained references will be invalid.

Parameters

[in]

image

The dimensions taken from image
