[OpenMap Users] RpfFrameCacheHandler.getSubframeData()

Don,

I am trying to understand the “getSubframeData()” method found in RpfFrameCacheHandler. Could you please explain to me why the value of “6” is important in this piece of code from that method?

--- START CODE ---

       RpfTocEntry entry = tocs[tocNumber].entries[entryNumber]; /* If beyond the image boundary, forget it */ if (y < 0 || x < 0 || entry == null || y >= entry.vertFrames * 6 || x >= entry.horizFrames * 6) { return null; } if (!entry.isFramesLoaded()) { tocs[tocNumber].loadFrameInformation(entry); } RpfFrameEntry frameEntry = entry.getFrame(y / 6, x / 6); /* Get the right frame from the frame cache */ RpfFrame frame = (RpfFrame) get(frameEntry);

--- END CODE ---

Thanks,
Adam
