   ImGearInterpolationOptions* options
) 

public:

   ImGearPage^ page,
   int width,
   int height,
   ImGearInterpolationOptions^ options
) 

Parameters

page

Source image from which the thumbnail is created.

width

Width of the thumbnail.

height

Height of the thumbnail.

options

Interpolation options.

Return Value

Interpolation options depend on the color space and bit depth of the image. Grayscale, PreserveBlack and PreserveWhite interpolations are applicable only to 1 bit images.

Average and Bilinear interpolations are not applicable to 1 bit images nor to images having a non-gray palette. Also, Bilinear interpolation cannot be applied to the images if one of the dimensions is decreased.

Use ImGearProcessingVerifier.CanApplyCreateThumbnail method to check whether the operation can be performed.
