Question Adrian Howe · Oct 16, 2023 Problem encoding pdf content stream to base 64 using the StoreFieldStreamBase64 method Hello, I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method. I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01). The transformer is being used in a business process. This is the code used in the transformer to encode the stream to base 64: #Business Process (BPL) #DTL #HL7 #Health Connect #InterSystems IRIS 0 2 0 392
