block factor block function block buffer size block to fit get block factor get block function get block buffer size get block cursor has block block factor
Set the current blocking factor. It does not have to be an integer.
Syntax: block factor numeric
block factor to numeric
block factor to numeric about coordinate # in physical coordinates
Example: block factor 4
block factor to 2
block factor to 2 about 100 100
block function
Set the current blocking mode.
Syntax: block function [average | sum]
Example: block function sumblock buffer size
Set the current blocking buffer size.
Syntax: block buffer size integer
Example: block buffer size 1024block to fit
Set the current blocking factor such that the entire image will fit the current frame size. The blocking factor will be rounded up to the next power of 2.
Syntax: block to fit
Example: block to fitget block factor
Return the current blocking factor.
Syntax: get block factor precision
Example: get block factor defaultget block function
Return the current blocking function. A value of AVERAGE or SUM is returned.
Syntax: get block function
Example: get block functionget block buffer size
Return the current blocking buffer size.
Syntax: get block buffer size
Example: get block buffer sizeget block cursor
Return the coordinate in physical coordinates that is the center of the blocking operation.
Syntax: get block cursor
Example: get block cursorhas block
Return true if FITS is a binary table
Syntax: has block
Example: has block
