Size. Alternatively, set the resulting size in the spatial dimensions X, Y, and – in case of Z-stacks –
Z. The corresponding Factor will be set automatically.
Ratio.
Maintain XY-ratio. If this option is selected, a change of the X Factor or X Size causes automatically a corresponding setting of the Y Factor or Y Size and vice versa.
Zoom axes independently. If this option is selected, it is possible to set, for example, different Factors for X and Y. Doing so leads to a distortion of the resulting image.
Zoom axes homogeneously. This option is available for Z-stacks only. Here all three Factors X, Y
and Z will always have the same size.
Interpolation
Resizing images will result in a reduction in image quality. This is because the color of each original
pixel must be redistributed across a different number of pixels and the result will be less precise
than the original. There will be an inevitable loss of sharpness, regardless of whether the image is
enlarged or made smaller.
Nearest Neighbor. This method doubles or removes pixels. The appearance of the new image
may be somewhat coarse.
Trilinear. This method interpolates the color of the original pixels to come to the new pixels.
Bicubic (XY), Linear (Z). This method interpolates the color of the original pixels to come to the
new pixels using a different algorithm in the X and Y dimensions as compared to the trilinear
method. The appearance of the resized image will be slightly less blurry.
