ImGearProcessing.Rotate(page, angle, mode, background, interpolation)

public static void Rotate( 
   ImGearPage page,
   double angle,
   ImGearRotationModes mode,
   ImGearPixel background,
   ImGearInterpolations interpolation
)

public: static void Rotate( 
   ImGearPage* page,
   double angle,
   ImGearRotationModes mode,
   ImGearPixel* background,
   ImGearInterpolations interpolation
) 

public:
static void Rotate( 
   ImGearPage^ page,
   double angle,
   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.

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.
