89fbaf8170 Keep track of the image size with the base image rather than the compressed image. It's not always the case that the image data is RGBA8 data. 2013-09-28 22:40:48 -04:00

e11e2d1c12 Actually use a log file instead of std::cout and remove a warning that's no longer applicable 2013-09-28 22:40:14 -04:00

289bcc9d44 Make the block index for the stat function the pointer reinterpreted as an integer. This way we know exactly what block it is because we simply need to sort the stats in the output log. 2013-09-28 22:39:27 -04:00

f1924bd221 Try to send a single string that encompasses a stat to the stream so that when we do synchronization it will crunch the entire string at once. 2013-09-28 21:43:25 -04:00

264e447e80 Deal with this bug once and for all. If we have an image in block stream order, then explicitly reorder it before doing any work. Then keep it that way. I probably could have fixed this in the amount of time I've wasted on it. -____- 2013-09-26 20:17:07 -04:00
