trimdata
(To be removed) Trim map data exceeding projection limits
The trimdata
function will be removed in a future
release.
Syntax
[ymat,xmat,trimpts] = trimdata(ymat,ylim,xmat,xlim,object)
Description
[ymat,xmat,trimpts] = trimdata(ymat,ylim,xmat,xlim,object)
identifies points in map data that exceed projection limits. The projection
limits are defined by the lower and upper inputs.
Note
To clip vector data that is represented by a shape object in planar
coordinates, use the mapclip
function. To crop raster data that is
represented by an array and a map raster reference object, use the
mapcrop
function.
The particular object to be trimmed is identified by the
object
input. Allowable objects are
'surface'
for trimming graticules'light'
for trimming lights,'line'
for trimming lines'patch'
for trimming patches'text'
for trimming text object location points'none'
