CIImageMBS class

// take a picture and scale it
Var pic As Picture = LogoMBS(500)
Var image As CIImageMBS = CIImageMBS.imageWithPicture(pic)

Var filter As New CIFilterLanczosScaleTransformMBS

Const targetWidth = 600.0
Const targetHeight = 400.0

Var scale As Double = targetHeight / image.Extent.Height
Var aspect As Double = targetWidth / (image.Extent.Width * scale)

filter.inputImage = image
filter.inputScale = scale
filter.inputAspectRatio = aspect

Var result As Picture = filter.outputImage.RenderPicture
