CorrectCalibratedImage Method

Syntax

CWIMAQVision.CorrectCalibratedImage SourceImage, DestImage [, Regions] [, ReplaceValue = 0.0] [, InterpolateMethod = cwimaqInterpolateZeroOrder ]

Return Type

Long

On success, this method returns 0. On failure, this method returns a negative number.

Purpose

Corrects a calibrated image by applying a calibration to create a spatially correct image.

Remarks

Use this method with image types U8, I16, SGL, RGB32, and HSL32.

Parameters

SourceImage As CWIMAQImage

The calibrated image to correct.

DestImage As CWIMAQImage

The corrected image.

Regions As Variant

[Optional] A CWIMAQRegions object representing the portion of the image the method corrects. If you do not supply this parameter, the method corrects the entire image.

ReplaceValue As Variant

[Optional] The pixel replace value for pixel points that cannot be corrected.

This parameter has a default value of 0.0.

InterpolateMethod As Variant

[Optional] A CWIMAQInterpolateMethods constant specifying the method of interpolation. Valid interpolation methods for correction are cwimaqInterpolateZeroOrder and cwimaqInterpolateBiLinear.

This parameter has a default value of cwimaqInterpolateZeroOrder .

Example

Dim i As New CWIMAQImage
Dim simpleCalibrationOptions As New CWIMAQSimpleCalibrationOptions

' Calibrate the image in Viewer1
simpleCalibrationOptions.CalibrationAxisInfo.Angle = 45
simpleCalibrationOptions.GridDescriptor.XStep = 10
simpleCalibrationOptions.GridDescriptor.YStep = 10
simpleCalibrationOptions.GridDescriptor.Unit = cwimaqCalUnitMeter
