I've been trying lately to display custom images on my Kobo Wifi. I've had no luck
finding any documentation for the Wifi's imx357 and e-ink on freescale's website,
and pygame fails to recognize the framebuffer. So I tried converting an image to the
rgb565 format with ffmpeg:

Code:

ffmpeg -vcodec png -i image.png -vcodec rawvideo -f rawvideo -pix_fmt rgb565 image.raw

and displaying it with the program "pickel" found on the Wifi, but the image it displays
is distorted, as seen here (original image is shown in top-left corner):

Anyone have any suggestions? I can't stand having my Wifi hacked and yet not being
able to draw to the screen! Plus I need something to do until I can get my hands on a
Glo or a Paperwhite.
