I am trying to send an image from my daemon (cpp) to the installation node through XML-RPC.
What is the best way to do this?
I have tried base64, but couldn’t understand how to receive it in Java.
I have also tried to send an array of strings (each string is a row, and each char is a pixel 0-255), but i got this error: org.apache.xmlrpc.XmlRpcException: Unexpected error executing code for particular method, detected by Xmlrpc-c method registry code. Method did not fail; rather, it did not complete at all. 200-byte supposed UTF-8 string is not valid UTF-8. Unrecognized UTF-8 initial byte value 0xff
Send image data as base64 and here is the code I used to create the image on java side.
(imageData) is the data received through whatever communication you end up using. It’s been awhile since I touched this code but the image is pulled of an html website converted to base64 in python then sent over to URCap which converts it into an image.
@roman.reiner Thanks for the answer, although you must have skipped through the most important part the definition for imageData, and how to convert it back to an Image.
BTW, how can a whole image fit in a 1D byte array? how would it know the height and width when parsing back?
My client is a cpp deamon, not Java, and my image is represented in a 2D byte array.
