Purpose
To get the current setting of alignment mode of string printing. The return value will be L (left), R (right) or C (center).
Usage
{String} ret = GETALIGN()
Example:
|
->align_mode = getalign()
->print align_mode L |
See also
set align
Purpose
To get the current angle mode, stored in a string. The returning result is "DEG", degree, or "RAD", radian, or "GRA", grade
Usage
{String} ret = GETANGLE()
Example:
|
->angle_mode = getangle()
->print angle_mode DEG |
See also
set angle
Purpose
To get the current block size, which is the size of a sub-block used in some image processing function, such as edgesobel, stretch, etc. Data processing using sub-block technique can increase speed and reduce the amount of required memory.
Usage
{int} ret = GETBLKSIZE()
Example:
|
->n = getangle()
->print n 64 |
See also
set blksize
Purpose
To get the current color map.
Usage
{Matrix_uch} ret = GETCOLORMAP()
Example:
|
->M = getcolormap()
->print M no of row : 64 |
See also
set colormap
Purpose
To get the current value of distance tolerance, which is used in some function in COGO, e.g. 3D line intersection.
Usage
{double} ret = GETDISTTOL()
Example:
|
->dist_tol = getdisttol()
-> |
See also
set disttol
Purpose
To get the current output format. The returning result is either "FIX", or "SCI".
Usage
{String} ret = GETFORMAT()
Example:
|
->f = getformat()
->print f SCI |
See also
set format
Purpose
To get the current output file name for commands "fprint" and "flist".
Usage
{String} ret = GETFOUT()
Example:

Purpose
To get the current interpolation mode, resample type. The returning result is "NEAREST", or "BILINEAR" or "BICUBIC".
Usage
{String} ret = GETINTP_MODE()
Example:
|
->resample = getintp_mode()
->print resample NEAREST |
See also
set intp_mode
Purpose
To get the current value of magic number, which is a constant used in some functions, e.g. estimated percent of noise in an image etc. The magic number cannot be set. Its sole purpose is to inform some of the important constants used in a particular function.
Usage
{double} ret = GETMAGIC_NUMBER()
Example:
|
->num = getmagic_number()
-> |

Purpose
To get the current number of the maximum number of iteration. This is a system integer variable that control the maximum number of iteration in functions that require an iteration processing, for example exterior orientation, 3D conformal transformation, etc.
Usage
{int} ret = GETMAX_NO_ITERATE()
Example:
|
->no = getmax_no_iterate()
->print no 20 |
See also
set max_no_iterate
Purpose
To get the current number of the maximum number of poly-line in vectors of poly-lines, e.g. VecIndx, VecPt2D, VecPt3D, VecRCpline, etc.
Usage
{int} ret = GETMAX_NO_PLINE()
Example:
|
->no = getmax_no_pline()
->print no 100000 |
See also
set max_no_pline
Purpose
To get the current value of n/a (not applicable). This value is used when no solution is found in some COGO functions, e.g. line intersection.
