23 -- findCells procedure
24 --
25 -- DESCRIPTION
26 -- generate a new georaster object based on the "condition" parameter.
27 -- The "condition" parameter is a boolean expression, for each pixel
28 -- in the inGeoRaster, the value of corresponding pixel of outGeoraster
29 -- is same, if "condition" is true, otherwise bgValues is used to set
30 -- the pixel's value of outGeoraster.
31 --
32 --
33 -- ARGUMENTS
34 -- inGeoRaster - The SDO_GEORASTER object to be applied with condition
35 -- condition - A boolean expression used to filter out pixels, the
36 -- syntax details are explained in GeoRaster Manual
37 -- storageParam - A string specifying storage parameters for the target
38 -- georaster object. The details are explained in GeoRaster
39 -- Manual
40 -- outGeoRaster - The new GeoRaster Object
41 -- bgValues - background values for filling pixels which make
42 -- conditon return false, if it is null, then 0 will
43 -- be used as background color.
44 -- nodata - if 'true', then keep original value for all nodata pixel
45 -- if 'false',then treat nodata as regular data.
46 -- parallelParam - specify if executing operations in parallel if
47 -- possible, but note if parameter parallelParam is 'true',
48 -- then some execution units of this procedure will run
49 -- as autonomous transactions, that means some changes
50 -- are submitted and you can't rollback.
