The two-dimensional image to resample. Can be of any data type except string.col
The number of columns to be in the resulting image. row
The number of rows to be in the resulting image.
Standard Library function that shrinks orexpands an image or array.
The two-dimensional image to resample. Can be of any data type except string.col
The number of columns to be in the resulting image. row
The number of rows to be in the resulting image.
The resampled image or array.
Specifies the interpolation method to be used in the resampling:
If nonzero, uses the bilinear interpolation method.
The nearest neighbor interpolation method is not linear, because new values that are needed are merely set equal to the nearest existing value of image. Therefore, when increasing the image size, the result may appear as individual blocks. For more information, see the PV-WAVE User's Guide.
