class FMETile

Bases: object

FME Tile Class

init()

FMETile is an abstract class. It cannot be created directly.

__init__

Initialize self. See help(type(self)) for accurate signature.

getByteArray()

Returns a list of bytearrays where each bytearray represents the data values of each row of the tile.

Return type:list[bytearray] Returns:The data values of the tile.

getDataAsStringArray(startRow, startCol, numRows, numCols)

Get a list that contains values of the tiles. One string is added to the list for each cell in the specified area. If the specified area falls outside the bounds of the tile, the string array will not be modified. ‘startRow’, ‘startCols’, numRows’, and ‘numCols’ should be integers greater than or equal to 0.

Parameters:

• startRow (int) – Starting row.
• startCol (int) – Starting column.
• numRows (int) – Number of rows to get.
• numCols (int) – Number of columns to get.

Return type:

list[string]

Returns:

Values in the tile.
