ENVI_GET_TILE

ENVI_GET_TILE

This routine is obsolete and has been replaced with ENVIRasterIterator.

This function returns the requested tile data. Tiles may be requested multiple times and in any order between the ENVI_INIT_TILE and ENVI_TILE_DONE calls.

Syntax


Result = ENVI_GET_TILE(Tile_ID, Cur_tile, BAND_INDEX=variable, YE=variable, YS=variable)

Arguments


Tile_ID

This is the tile ID returned from ENVI_INIT_TILE.

Cur_tile

This is the tile number for the requested tile. This number must be between 0 and the number of tiles minus 1.

Keywords


BAND_INDEX

If the current file is in BSQ tile interleave format, use this keyword to specify a named variable that contains the index to the current band.

YE

Use this keyword to specify a named variable that contains the ending y value for the current tile, in file coordinates.

YS

Use this keyword to specify a named variable that contains the starting y value for the current tile, in file coordinates. For spatially subsetted images, the first YS is equal to the first line in the subset image, which is not necessarily line 0.
