Detailed Description

This property describes the way the axes must be interpreted (IMAGE, VOLUME, SEQUENCE...) and also the composition of the image by providing :

  • its interpretation (GRAYSCALE, RGB, ...)
  • the presence of a alpha channel
  • the bit depth where data is stored
  • the range of value of the data (It is actually the min and max values that are stored in the image)

Constructor & Destructor Documentation

◆ ImageInfoProperty() [1/4]

iolink::ImageInfoProperty::ImageInfoProperty ( ImageType  axesInterpretation,
ImageInterpretation  interpretation,
bool  hasAlpha,
size_t  bitDepth,
const Vector2d valueRange 
)

Constructor.

Parameters
axesInterpretationAxes interpretation for the image
interpretationThe image interpretation
hasAlphaIndicate if an Alpha channel is present
bitDepthBit count effectively used to store each component of the pixel
valueRangeRange of value of the component

◆ ImageInfoProperty() [2/4]

iolink::ImageInfoProperty::ImageInfoProperty ( ImageType  axesInterpretation,
ImageInterpretation  interpretation,
bool  hasAlpha,
DataType  dataType 
)
explicit

Short constructor using the given data type standard properties to initialize with default values.

Parameters
axesInterpretationAxes interpretation for the image
interpretationThe image interpretation
hasAlphaIndicate if an Alpha channel is present
dataTypeDataType to use as reference to initialize member data.

◆ ImageInfoProperty() [3/4]

iolink::ImageInfoProperty::ImageInfoProperty ( DataType  dataType)
explicit

Shorter constructor using the given data type standard properties to initialize.

BitDepth and value range is initialized thanks to dataType. hasAlpha property is set to False. Other properties are set to UNKNOWN.

Parameters
dataTypeDataType to use as reference to initialize member data.

◆ ImageInfoProperty() [4/4]

iolink::ImageInfoProperty::ImageInfoProperty ( ImageType  axesInterpretation,
DataType  dataType 
)

Shorter constructor using the given Image Type and Data type standard properties hasAlpha property is set to False.

Image interpretation is set to UNKNOWN.

Parameters
axesInterpretationAxes interpretation for the image
dataTypeDataType to use as reference to initialize member data.

Member Function Documentation

◆ axesInterpretation()

ImageType iolink::ImageInfoProperty::axesInterpretation ( ) const

Return an ImageType describing the interpretation of the axes of the image.

For example a classical image ImageType will have the ImageDimension::COLUMN and ImageDimension::ROW set. A sequence of 2D images will have ImageDimension::SEQUENCE in addition.

◆ bitDepth()

size_t iolink::ImageInfoProperty::bitDepth ( ) const

The bit depth of pixel components.

For example, data can be stored on 16 bits, but only 12 of those are used, so the image view will have a data type of UINT16, but its real bit depth will be 12.

◆ channelCount()

static size_t iolink::ImageInfoProperty::channelCount ( ImageInterpretation  interpretation)
static

Method which gives you the number of channels for one pixel in a specific ImageInterpretation.

Parameters
interpretationImageInterpretation for which we want to know the channel count
Returns
the channel count corresponding to the given ImageInterpretation

◆ setAxesInterpretation()

void iolink::ImageInfoProperty::setAxesInterpretation ( ImageType  type)

Set the image's axes interpretation.

Parameters
typeType of Image to set
