====== Calc Integral Map ======

===== Description =====

Generates an integral image (summed-area table) from a map: each output cell holds the cumulative sum of all cells up to and including its position. See [[https://en.wikipedia.org/wiki/Summed-area_table|Summed-area table]] for background on the technique.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Input  | [[Map Type]]  | Map the cumulative sum is calculated from.  |

===== Optional Inputs =====

^ Name  ^ Type  ^ Description  ^ Default Value  ^
| Use Full Precision  | [[Boolean Value Type]]  | If true, the output map uses the largest available cell type, avoiding precision errors when the running sum could exceed Input's cell type range.  | No  |

===== Outputs =====

^ Name  ^ Type  ^ Description  ^
| Result  | [[Map Type]]  | Resulting integral map.  |
