Naming when cropping with multiple polygons

PeterSanctus

Hello fellow Gm Scripters,

i'm trying to create geotiff from an arcinfo file, and cropp the geotiff with polygons that are in a dgn file. The dgn file only have 2 layers, a layer with squares and a layer with texts. Those texts are in each one off the squares.

what I want to do is create geotiffs with names of texts that are within each square, i.e, the geotiff will be croped with the squares, wich I can do, and then GM name the files with the texts in dgn file.

I tried POLYGON_CROP_NAME_ATTR but it only gives-me the name of the layer, I cannot reach the values in the specific layer in dgn.

EXPORT_ELEVATION \
    FILENAME="G:\GM\.tif" \
    TYPE=GEOTIFF \
    SPATIAL_RES=10.0 \
    BYTES_PER_SAMPLE=4 \
    GEN_WORLD_FILE=YES \
    POLYGON_CROP_FILE="G:\GM\tiles7.dgn" \
    POLYGON_CROP_USE_EACH=YES \
    POLYGON_CROP_BBOX_ONLY=YES \
    POLYGON_CROP_NAME_ATTR=???

does anyone done this?
