PEMVerifier

|
|
===========
|
||
|
|
|
||
|
|
.. function:: PEMVerifier(vnode clip[, float[] upper, float[] lower])
|
||
|
|
:module: std
|
||
|
|
|
||
|
|
The *PEMVerifier* is used to check for out-of-bounds pixel values during filter
|
||
|
|
development. It is a public function so badly coded filters won't go
|
||
|
|
unnoticed.
|
||
|
|
|
||
|
|
If no values are set, then *upper* and *lower* default to the max and min values
|
||
|
|
allowed in the current format. If an out of bounds value is
|
||
|
|
encountered a frame error is set and the coordinates of the first bad pixel
|
||
|
|
are included in the error message.
