Detailed Description

Decimation is used to decrease the image size.

This method reduces resolution by selecting (i.e., skipping) pixels at regular intervals along, columns (x), rows (y) or both. It is computationally efficient but may introduce aliasing.

Note

Processes the entire image, ignoring any specified image region. As with binning, the alpha channel of the input image (if present) is also ignored during decimation. It is always set to the maximum possible pixel value.

Warning

Decimation permanently reduces image resolution. The original resolution cannot be recovered after decimation is applied.

Defaults

• x = 1
• y = 1
• peak::pipeline::detail::DownsamplingMode::Decimation

Constructor & Destructor Documentation

DecimationFeature()

DecimationFeature ( detail::DownsamplingModule & module )

inlineexplicit

Creates a DecimationFeature for an existing downsampling module.

Parameters

module

Reference to the underlying detail::DownsamplingModule.

Member Function Documentation

GetRange()

peak::common::IntervalU GetRange ( ) const

inline

Gets the valid range for the decimation factors x and y.

The returned interval specifies the minimum and maximum values that can be passed to SetX or SetY.

Returns

An IntervalU representing the valid decimation factor range.

Since

ids_peak_icv 1.0

Definition at line 201 of file peak_icv_decimation_feature.hpp.

GetX()

uint32_t GetX ( ) const

inline

Gets the current number of columns used for decimation.

Returns

The current number of columns used for decimation. The decimation algorithm uses one column, skips the next x - 1 columns, and repeats this process.

Since

ids_peak_icv 1.0

Definition at line 191 of file peak_icv_decimation_feature.hpp.

GetY()

uint32_t GetY ( ) const

inline

Gets the current number of rows used for decimation.

Returns

The current number of rows used for decimation. The decimation algorithm uses one row, skips the next y - 1 rows, and repeats this process.

Since

ids_peak_icv 1.0

Definition at line 196 of file peak_icv_decimation_feature.hpp.

IsEnabled()

bool IsEnabled ( ) const

inlineoverridevirtual

Indicates whether the feature is currently enabled.

Returns

true if enabled; otherwise, false.

Since

ids_peak_icv 1.0

Implements IFeature.

Definition at line 151 of file peak_icv_decimation_feature.hpp.

ResetToDefault()

void ResetToDefault ( )

inlineoverridevirtual

Resets all settings to the default values.

Note

The enabled state does not change when calling this function.

Since

ids_peak_icv 1.0

Implements IFeature.

Definition at line 156 of file peak_icv_decimation_feature.hpp.

SetEnabled()

void SetEnabled ( bool enabled )

inlineoverridevirtual

Enables or disables the feature.

Parameters

enabled

Set to true to enable the feature, or false to disable it.

Since

ids_peak_icv 1.0

Implements IFeature.

Definition at line 146 of file peak_icv_decimation_feature.hpp.

SetX()

void SetX ( uint32_t x )

inline

Sets the number of columns used for decimation.

Parameters

x	The number of columns used for decimation. The decimation algorithm uses one column, skips the next x - 1 columns, and repeats this process. Valid values are within the range returned by GetRange.

Exceptions

OutOfRangeException

If x is outside the valid range.

Definition at line 161 of file peak_icv_decimation_feature.hpp.

SetY()

void SetY ( uint32_t y )

inline

Sets the number of rows used for decimation.

Parameters

y	The number of rows used for decimation. The decimation algorithm uses one row, skips the next y - 1 rows, and repeats this process. Valid values are within the range returned by GetRange.

Exceptions

OutOfRangeException

If y is outside the valid range.
