Quoted from AlanJ:code to use the most optimised jpeg decoder library, and it still isn't fast enough.
What about non-compressed images? Like PNG or plain'ol GIF?

Quoted from pete_d:They are just "non-lossy" formats, whereas JPEG is "lossy". With PNG and GIF you get exactly the same pixels back after compressing and decompressing, while JPEG will invariably involve subtle differences (but typically not noticeable to the human eye). With any of those formats, there will be a decompression step.
It depends on what is slowing the 'decompressing' - what's taking the time, actually reading the files off memory/sd? Or converting the files into the data that the TFT needs? Depending on what the bottleneck is, another format may work better.
GIF, for example, has an indexed color scheme, and has less data needed to be read and processed for the same amount of pixels.
Quoted from Mudflaps:I’m in for a 6 digit set. This will fit in the playfield window for Medusa, right?
Huh - Interesting thought. Getting one for a Mr and Ms Pacman, with Pac-Man styled digits for the playfield window. That's not a bad idea..!
