RotateImage (Exp)

Rotate an image by an individual rotation angle in degrees.
Can use available TwinCAT Job Tasks for executing parallel code regions.

Syntax

Definition:

HRESULT RotateImage(
    HRESULT                        hrPrev,
    ITcVnImage*                    ipSrcImage,
    ITcVnImage*&                   ipDestImage,
    double                         fAngleDeg,
    bool                           bAdjustDestSize,
    ETcVnInterpolationType         eInterpolationType = IT_BILINEAR,
    ETcVnBorderInterpolationMethod eBorderInterpolation = BIM_CONSTANT,
    TcVnVector4_LREAL&             aBorderValue = {0, 0, 0, 0}
)

Parameters

Name

Type

Default

Description

hrPrev

HRESULT

 

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipSrcImage

ITcVnImage*

 

Source image

ipDestImage

ITcVnImage*&

 

Destination image (An appropriate image will be created if required.)

fAngleDeg

double

 

Rotation angle in degree (positive: counter-clockwise, negative: clockwise)

bAdjustDestSize

bool

 

If true, ipDestImage size is adjusted so that the whole rotated ipSrcImage is contained. Otherwise, ipDestImage size is set to ipSrcImage size.

eInterpolationType

ETcVnInterpolationType

IT_BILINEAR

Interpolation method

eBorderInterpolation

ETcVnBorderInterpolationMethod

BIM_CONSTANT

Border interpolation method (ISOLATED not supported)

aBorderValue

TcVnVector4_LREAL&

{0, 0, 0, 0}

Border value, if CONSTANT is used
