import sys
import chilkat

success = False

json = chilkat.CkJsonObject()

# Load the JSON.
success = json.LoadFile("qa_data/json/JSR5U.json")
if (success != True):
    print(json.lastErrorText())
    sys.exit()

# The JSON we loaded contains this:

# 	{
# 	...
# 	...
# 	  "data": {
# 	    "content": "JVBERi0xLjQ..."
# 	  }
# 	...
# 	...
# 	}

sb = chilkat.CkStringBuilder()
json.StringOfSb("data.content",sb)

bd = chilkat.CkBinData()
bd.AppendEncodedSb(sb,"base64")

success = bd.WriteFile("qa_output/a0015.pdf")
