# GempakMcidasImgLinkRequest
|
|
#
|
|
# This code has been developed by the SIB for use in the AWIPS2 system.
|
|
# Performs a BaseRequest for a McIDAS image from GEMPAK, and stores
|
|
# the image data in the uEngineProducts directory for later transfer.
|
|
#
|
|
## Usage:
|
|
# import GempakMcidasHdrRequest
|
|
# dataRequest = GempakMcidasHdrRequest.GempakMcidasHdrRequest()
|
|
# dataRequest.setImageType("...")
|
|
# dataRequest.setAreaName("...")
|
|
# dataRequest.setResolution("...")
|
|
# dataRequest.setTime("...")
|
|
# return dataRequest.execute()
|
