- horizontal System.Boolean
- vertical System.Boolean
- cancellationToken System.Threading.CancellationToken = default
public static ValueTuple<Int32, Int32> GetRotatedSize(OfficeRasterImage source, Double degrees) #Returns:
ValueTuple<Int32, Int32>Plans the exact canvas dimensions produced by a clockwise rotation without allocating pixels.
Parameters
- source OfficeIMO.Drawing.OfficeRasterImage
- degrees System.Double
public static ValueTuple<Int32, Int32> GetSkewedSize(OfficeRasterImage source, Double degreesX, Double degreesY) #Returns:
ValueTuple<Int32, Int32>Plans the exact expanded canvas dimensions produced by a skew without allocating pixels.
Parameters

- degreesX System.Double
- degreesY System.Double
public static OfficeRasterImage MaskEllipse(OfficeRasterImage source, Double x, Double y, Double width, Double height, CancellationToken cancellationToken = default) #Returns:
OfficeRasterImageKeeps pixels inside an antialiased ellipse and clears pixels outside it.
Parameters
- source OfficeIMO.Drawing.OfficeRasterImage
- x System.Double
- y System.Double
- width System.Double
- height System.Double
- cancellationToken System.Threading.CancellationToken = default
public static OfficeRasterImage MaskPolygon(OfficeRasterImage source, IReadOnlyList<OfficePoint> points, CancellationToken cancellationToken = default) #Returns:
OfficeRasterImageKeeps pixels inside an antialiased polygon.
Parameters
- source OfficeIMO.Drawing.OfficeRasterImage
- points System.Collections.Generic.IReadOnlyList{OfficeIMO.Drawing.OfficePoint}
- cancellationToken System.Threading.CancellationToken = default
public static OfficeRasterImage MaskRoundedRectangle(OfficeRasterImage source, Double radius, CancellationToken cancellationToken = default) #Returns:
OfficeRasterImageClears pixels outside the rounded corners of the image canvas.
Parameters

- radius System.Double
- cancellationToken System.Threading.CancellationToken = default
public static OfficeRasterImage Rotate(OfficeRasterImage source, Double degrees, Nullable<OfficeColor> background = null, CancellationToken cancellationToken = default) #Returns:
OfficeRasterImageRotates clockwise and expands the canvas to retain the entire source.
Parameters

- cancellationToken System.Threading.CancellationToken = default
public static OfficeRasterImage Skew(OfficeRasterImage source, Double degreesX, Double degreesY, Nullable<OfficeColor> background = null, CancellationToken cancellationToken = default) #Returns:
OfficeRasterImageSkews each axis by its angle in degrees and expands the canvas to retain all pixels.
Parameters
