I will try to answer to both points: In the first article, I described how I fetched the picture by reading the virtual framebuffer. I have not any knowledge of what’s being drawn. All I have from the beginning is a 2.5Mb byte array. I don’t use any jpeg compression anymore in this version And my understanding is that the native client is transmitting the vector representation to the client and the client redraws it with the same algorithm. It is only doable if you know what algorithm they use. I did a small test to decode their format, but it may change more often than the format of the picture. Does it provide you the answer? (thanks for the conversation)
