# test_ql-png-options.sh - test png(mdd,options) function of rasql
#
# SYNOPSIS:
# test_ql-png-options.sh
#
# DESCRIPTION
# Performs test queries to check whether transparency and background
# option works in function png(_,_).
#Write log to stdout/stderr for ???
# Does not test general image encoding!
#
# RESPONDING TO INCIDENT
# Incident_2005-07-12_IGN_png-transparency
#
# PROCEDURE
# - create test collections and objects
# - perform rasql calls, check output and, where applicable, the image generated
# check that (i) file is generated, (ii) has transparency color set appropriately
# - remove output files and test collections
#
# PRECONDITIONS
# - rasql binary available in the $RMANBASE/applications/rasql development directory
# - rasdaman up and running,
# - database allows write access using user/password as defined below
# - ImageMagick installed to have 'identify' utility
# - can create subdir in cwd
#
# RETURN CODES
RC_OK=0 # everything went fine
RC_ERROR=1 # something went wrong
#
# CHANGE HISTORY
# 2005-jul-26 P.Baumann created
# 2005-aug-25 P.Baumann use raiseError() to centralize bailout behavior
#
# COMMENTS
# - add test for INV_PNG()
