ImageGear.Core Assembly / ImageGear.Processing Namespace / ImGearProcessing Class / Rotate Method / Rotate(ImGearPage,Double,ImGearRotationModes,ImGearPixel,ImGearInterpolations) Method
Image to rotate.
Rotation angle in degrees.
Rotation mode (clip or expand).
Background color to fill the out of picture area; null (Nothing in VB NET) results in black background.
Interpolation to use for rotation.

       ImGearRotationModes mode,
       ImGearPixel^ background,
       ImGearInterpolations interpolation
    ) 

    Parameters

    page
    Image to rotate.
    angle
    Rotation angle in degrees.
    mode
    Rotation mode (clip or expand).
    background
    Background color to fill the out of picture area; null (Nothing in VB NET) results in black background.
    interpolation
    Interpolation to use for rotation.
    Remarks
    This method processes all channels of the image as well as image's ROI, if it exists.

    Background should be in the same color space as the Page, including Alpha and Extra channels. Background must have the same channel count and bit depth as a DIB?s color space.

    Use CanApplyRotate method to check whether the operation can be performed.

    Supported interpolations are BILINEAR and BICUBIC. Interpolation is supported for non-indexed images, and for indexed images with grayscale palette. It is not supported for 1bpp images.
