Parameters

IPDefectX1

The x-coordinate of the starting point of the scratch to be removed.

This value must be greater than or equal to 0.

IPDefectY1

The y-coordinate of the starting point of the scratch to be removed.

This value must be greater than or equal to 0.

IPDefectX2

The x-coordinate of the ending point of the scratch to be removed.

This value must be greater than or equal to 0.

IPDefectY2

The y-coordinate of the ending point of the scratch to be removed.

This value must be greater than or equal to 0.

IPDefectLineWidth

The width of the scratch in pixels.

This value must be greater than or equal to 1.

IPDefectThreshold

An integer value which controls how bright a pixel must be before it is considered a scratch.

Valid range is between -255 and 255.

The default value is 0.

IPDefectFilterAdjustment

An integer value which controls where the filter boundary begins relative to the scratch for smoothing to occur.

Valid range is between -6 and 2.

The default value is 0.

IPDefectSmoothingAdjustment

An integer value which controls how much smoothing is applied to the pixels in the scratch.

Valid range is -5 and 100.

The default value is 0.

IPDefectType

Value	Description
DefectTypeDark	A dark defect is to be removed.
DefectTypeLight	A light defect is to be removed.

An enumDefectType enumeration used in determining what type of scratch to process.

Remarks

Prior to calling RemoveScratches, an Area must be set, using the Area method.

If the starting and ending points of the scratch are identical, an IX_Error_InvalidScratchLinePoints error is returned.
