| badPgDev | error |
| | The pgdev string is not in the correct  optional outFilename /device format.
|
| zeroUnsatFrac | error |
| | The value of unsatfrac must be greater than zero.
|
| unknownEband | error |
| | The BAND attribute of one of the input image arrays has an unrecognised value.
|
| zeroWhiteFlux | error |
| | One of the three RGB values of the reference colour equals zero. (This can happen if kevofwhite is too small.)
|
| badEbandOrder | error |
| | The images are not listed in order of increasing energy band.
|
| differentSizes | warning |
| | The three input images do not all have the same size.
corrective action: The smaller images are padded with zeros to the size of the largest.
|
| totallySaturated | warning |
| | The whole image is saturated.
corrective action: Run the task again with a larger value of unsatfrac.
|
| zeroClrVolume | warning |
| | The entire image has just one colour.
corrective action: A monochrome plot is produced, but this won't be very interesting. Figure out the problem and run the task again with better images.
|
| sameEband | warning |
| | Two or more of the images have the same value of the BAND keyword.
corrective action: The task proceeds anyway - maybe the user wants it this way.
