+ *
+ * PhotrimIncidence test given a single 5x5 input cube with 1 band.
+ * The shapemodel set in cube is utilized. All pixels outside the
+ * range as defined by minemission and maxemission are set to Null.
+ * Resulting pixel values are as shown below.
+ *
+ * | N| N| 3| 4| 5| Valid Pixels: 17
+ * | 6| 7| 8| 9|10| Histogram Sum: 189
+ * |11|12|13|14|15| Histogram Avg: 11.117647058823529
+ * |16|17|18| N| N|
+ * |21| N| N| N| N|
+ *
+ * The output cube is verified by checking histogram statistics.
+ *
+ * INPUT: testCube from DefaultCube fixture resized to 5x5 pixels
+ * with one band.
