ER Mapper [.ECW] Import Automation Options
Since the Import Options dialog is not displayed when the program is driven from an automation script, an options string can be specified in the script. The string consists of comma-separated parameters, which specify the behavior of the various import options. A typical example would be:
"Scale=16"
This would reduce the scale of the map to 1/16th .

Option |
Action |
Default |
Description |
|
Scale |
1 = 1/1 (uses most memory, best quality) 2 = 1/2 4 = 1/4 8 = 1/8 16 = 1/16 32 = 1/32 (uses least memory, lowest quality) |
1 |
Since some images can be extremely large once expanded into memory, the import filter allows the image to be reduced in dimensions by 1/2 to 1/32 of the original size. |
|
LRX |
integer |
maximum X |
Use LRX to limit the import to a subregion of the file. LRX is the X pixel coordinate for the lower right corner of the desired subregion. |
|
LRY |
integer |
maximum Y |
Use LRY to limit the import to a subregion of the file. LRY is the Y pixel coordinate for the lower right corner of the desired subregion. |
|
ULX |
integer |
0 |
Use ULX to limit the import to a subregion of the file. ULX is the X pixel coordinate for the upper left corner of the desired subregion. |
|
ULY |
integer |
0 |
Use ULY to limit the import to a subregion of the file. ULY is the Y pixel coordinate for the upper left corner of the desired subregion. |
Remarks
The pixel coordinates increase in the X direction from left to right and increase in the Y direction from top to bottom. The pixel coordinate origin is the upper left corner. For example an image with a 2000 pixel width and 3000 pixel height has the following coordinates: the upper left corner is coordinate (0,0) and the lower right corner is the x and y maximums (2000,3000).
However, the image still will import correctly even if the ULY is used for the maximum Y and LRY is used for the minimum Y.
