We have a function file_search in our library

bmp_file=file_search('img.bmp',/use_path)

http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/file_search.tar.gz
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/file_search.sav

On the other hand you may use a color definition routine like

http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/ct_ncdf.tar.gz
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/ct_ncdf.sav

Or would you like to have a funtion like

bmp=bmp_definitions('play')

http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/bmp_definitions.tar.gz
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/bmp_definitions.sav

For further routines and copyright and licence.
