Unwrap Method
Syntax
CWIMAQVision.Unwrap SourceImage, DestImage, Annulus [, BaselineOrientation = cwimaqBaselineOrientationInside] [, InterpolationMethod = cwimaqInterpolateBiLinear]
Return Type
On success, this method returns 0. On failure, this method returns a negative number.
Purpose
Unwraps a circular strip from an image into a rectangular strip.
Remarks
Use this method with U8, I16, SGL, and RGB32 images.
Parameters
SourceImage As CWIMAQImage
The input image.
DestImage As CWIMAQImage
The resulting image.
Annulus As CWIMAQAnnulus
Defines the circular strip.
BaselineOrientation As Variant
[Optional] A CWIMAQBaselineOrientations constant that specifies the orientation of the image data within the circular strip.
This parameter has a default value of cwimaqBaselineOrientationInside.
InterpolationMethod As Variant
[Optional] A CWIMAQInterpolateMethods constant that specifies the interpolation algorithm used in the unwrapping process.
This parameter has a default value of cwimaqInterpolateBiLinear.
