Parameters

sourceImage

Pointer to the source image/ROI.

sourceImagePivotX

Pivot point abscissa in the source image.

sourceImagePivotY

Pivot point ordinate in the source image.

destinationImagePivotX

Pivot point abscissa in the destination image.

destinationImagePivotY

Pivot point ordinate in the destination image.

scaleX

Scale factor for the abscissas. Its value must be different than 0.0.

scaleY

Scale factor for the ordinates. Its value must be different than 0.0.

rotation

Anti-clockwise rotation angle, using the current angle unit.

destinationImage

Pointer to the destination image/ROI. May not be the same as the source image.

interpolationBits

Number of bits of accuracy for interpolation. Allowed values are 0 (no interpolation, nearest neighbor), 4 (linear interpolation) or 8 (cubic interpolation).

region

Region to apply the function on.

Remarks

For resampling, the nearest neighbor rule or bilinear interpolation with 4 or 8 bits of accuracy is used.
The pivot point is a given point in the source image which is mapped to a given point in the destination image. Rotation and scaling are done around the pivot point. The pivot point reference coordinates are based on the 'Pixel Coordinate System', meaning that the origin (0, 0) is the center of the top left pixel of the image.
Out-of-image-bounds pixels are black.
When using a region, only the pixels contained in this region will be taken into account.
