ZBFRESAMPLE

Resamples a ZBF file to a new width and point spacing.

Syntax:

ZBFRESAMPLE filename, nx, ny, wx, wy, decenterx, decentery
 

Discussion:

This keyword requires the name of the ZBF file and six numbers. The beam will be resampled and interpolated as required to create a new beam file with nx and ny points, of total width wx and wy, in the x and y directions respectively. The nx and ny values must be powers of 2; such as 32, 64, 128, etc. The decenterx and decentery values may be provided to optionally decenter the new beam relative to the old beam. If either nx or ny is zero, no change is made to the existing beam sampling. If either wx or wy is zero, no change is made to the existing beam width. The length units in the ZBF file are converted automatically to the current lens units. The resulting data is written back to the same file name.

Example:

ZBFRESAMPLE "TEST.ZBF", 128, 128, 25.4, 25.4, 0, 0.4
