Resource: threshold
| Resource | threshold |
|---|---|
| Overview | Specifies the cutoff values for converting values to an image. |
| Command Line | -th=val,val,... |
| Environment Variable | wxpthres |
| Possible Values | |
| Default Value | Program dependent |
The threshold resource the cutoff values for converting data values to an image. This is currently used in the radar mosaic programs like prog:nids2image. The values are separated by commas. A range of values can be specified as low,high/delta. So a range from 0 to 75 with a interval of 5 could be specified as 0-75/5. The first value listed will get mapped to pixel value 0 in the image. The next one will get 1 and so on. Since WXP has valued images, the actual pixel value does not need to be known and the image can be processed by its values as specified in the threshold.
