Detailed Description

DeepPixel is a helper class for accessing DeepPlanes. It represents all the data at a particular x/y position in a DeepPlane. It does not contain its own copy of the data, and remains valid for only as long as the DeepPlane it is associated with exists.

Member Enumeration Documentation

enum DD::Image::DeepPixel::Ordering

which ordering the pixel data is in.

Enumerator:

eZAscending	unordered - the samples are in no particular depth order
eZDescending	z ascending - the samples with lowest Z are first

Member Function Documentation

static Ordering DD::Image::DeepPixel::SwapOrdering

(

Ordering

ordering

)

[inline, static]

Swap the pixel ordering to the other way around. Unordered remains unordered, but Z-ascending and Z-descending swap.

const ChannelMap& DD::Image::DeepPixel::channels

(

)

const [inline]

Get the channels that this DeepPixel contains

Referenced by DD::Image::DeepOutputPlane::addPixel(), and DD::Image::DeepSample::DeepSample().

size_t DD::Image::DeepPixel::getSampleCount

(

)

const [inline]

Get the number of samples

const float* DD::Image::DeepPixel::data

(

)

const [inline]

Get the pointer to the data

Referenced by DD::Image::DeepOutputPlane::addPixel().

size_t DD::Image::DeepPixel::getDataCount

(

)

const [inline]

Get the total number of data elements

Referenced by DD::Image::DeepOutputPlane::addPixel().

const float* DD::Image::DeepPixel::getUnorderedSample

(

size_t

sampNo

)

const [inline]

Get a pointer to the pixel data for a particular sample number. Data will be the channels present in channels(), ordered by numeric channel id. Samples are in whatever order they happen to be in the pixel.

Referenced by DD::Image::DeepSample::DeepSample().

const float& DD::Image::DeepPixel::getUnorderedSample	(	size_t	sampNo,
		DD::Image::Channel	channel
	)		const [inline]

Get a particular sample and channel. Samples are in whatever order they happen to be in the pixel.

const float & DD::Image::DeepPixel::getOrderedSample	(	size_t	depthIdx,
		DD::Image::Channel	channel
	)		const

Get a particle sample (by depth) and channel. Samples will be ordered so that if depthIdx == 0, it will fetch the sample with the lowest Z.
