To perform the Stretch operation on all raster maps in a map list, type one of the following expressions on the command line of the Main window:
|
OUTMAPLIST |
= |
MapListApplic(InputMapListName, MapStretchLinear(##, Range from, Domain)) |
|
OUTMAPLIST |
= |
MapListApplic(InputMapListName, MapStretchLinear(##, Range from, Domain, Range to)) |
|
OUTMAPLIST |
= |
MapListApplic(InputMapListName, MapStretchHistEq(##, Range from, Intervals)) |
where:
|
OUTMAPLIST |
is the name of the output map list map; all output raster maps will be created when the map list is opened, the raster maps will obtain the same name as the map list followed by _1, _2, _3, etc. |
|
MapListApplic |
is the command to start an operation on all raster maps in a map list. |
|
InputMapListName |
is the name of the input map list which contains all raster maps on which the operation should be performed. |
|
MapStretchLinear |
is the command to start the Stretch operation with linear stretching. |
|
MapStretchHistEq |
is the command to start the Stretch operation with histogram equalization. |
|
## |
is an obligatory parameter in map list expressions; it indicates the individual raster maps in the input map list. |
|
Range from |
|
|
Domain |
|
|
Range to |
|
|
Intervals |
When the definition symbol = is used, a dependent output map list is created. When the map list is opened and thus calculated, the dependent output raster maps will be defined and calculated.
When the assignment symbol := is used, the output raster maps will be defined and calculated, then the dependency links of the output raster maps will be broken.
