Hello,

I can not reproduce the bug for now (the part of the image shifted to the left) , I'm on Windows.But I also did not try all the encoder settings, can you give me your command line that leads to this bug? -Also very unlikely, be sure that your bitmap source image has a 54-bytes header...-

Many thanks for testing NHW. Cheers, Raphael

I didn't use any settings.

nhw_encoder  1.bmp 
hw_decoder 1.nhw

I have used imagemagick to resize and crop the image to 512x512. convert ~/Pictures/wallhaven-ymogyx.png -resize x512 -gravity center -crop 512x512+0+0 /tmp/1.bmp

The bmp file which I use. https://0x0.st/-qtu.zip

Yes, it's that special type of bitmap file that is not handled by NHW.Supported bitmap input images must have a 54-bytes header, in short, size of the input 512x512 24bits bitmap image must be 786486 bytes.

If you are under windows, you can use Paint for example, to save (as bitmap 24bits) your initial unsupported bitmap image and so convert it to the supported one.

Hope it could help. Cheers, Raphael
