# Geometry Adjustment Filters Translate, scale, and rotate images in 2D and 3D. ## Topics ### Filters [`+ bicubicScaleTransformFilter`](/documentation/CoreImage/CIFilter-swift.class/bicubicScaleTransform()) Produces a high-quality scaled version of an image. [`+ edgePreserveUpsampleFilter`](/documentation/CoreImage/CIFilter-swift.class/edgePreserveUpsample()) Creates a high-quality upscaled image. [`+ keystoneCorrectionCombinedFilter`](/documentation/CoreImage/CIFilter-swift.class/keystoneCorrectionCombined()) Adjusts the image vertically and horizontally to remove distortion. [`+ keystoneCorrectionHorizontalFilter`](/documentation/CoreImage/CIFilter-swift.class/keystoneCorrectionHorizontal()) Horizontally adjusts an image to remove distortion. [`+ keystoneCorrectionVerticalFilter`](/documentation/CoreImage/CIFilter-swift.class/keystoneCorrectionVertical()) Vertically adjusts an image to remove distortion. [`+ lanczosScaleTransformFilter`](/documentation/CoreImage/CIFilter-swift.class/lanczosScaleTransform()) Creates a high-quality, scaled version of a source image. [`+ perspectiveCorrectionFilter`](/documentation/CoreImage/CIFilter-swift.class/perspectiveCorrection()) Transforms an image’s perspective. [`+ perspectiveRotateFilter`](/documentation/CoreImage/CIFilter-swift.class/perspectiveRotate()) Rotates an image in a 3D space. [`+ perspectiveTransformFilter`](/documentation/CoreImage/CIFilter-swift.class/perspectiveTransform()) Alters an image’s geometry to adjust the perspective. [`+ perspectiveTransformWithExtentFilter`](/documentation/CoreImage/CIFilter-swift.class/perspectiveTransformWithExtent()) Alters an image’s geometry to adjust the perspective while applying constraints. [`+ straightenFilter`](/documentation/CoreImage/CIFilter-swift.class/straighten()) Rotates and crops an image. ### Protocols [`CIBicubicScaleTransform`](/documentation/CoreImage/CIBicubicScaleTransform) The properties you use to configure a bicubic scale transform filter.
