Alternatively, there's an fbgrab build in USBNetwork that'll do the trick

This should show the problem where the kindle is stretching the image:

Also is there a way to prevent the system from redrawing the status bar?

Hi! I just rooted my Kindle 4, and I may have a solution for this issue (in case anyone reads this...)

For me, the issue was that images were scaled 3x horizontally. This is because the images were saved with RGB color information for each pixel, instead of just one value for greyscale.

The solution was to open the image in an image editor (I'm using GIMP), set Image -> Mode -> Grayscale, and then save as .png or (non-progressive) .jpg . This worked!

Here's how it looks: https://imgur.com/a/KmnUzNP

Shameless plug: Hi! My name is FBInk, and I can print images properly!.

Although, to be fair, I still highly recommend to properly preprocess images for best results.
