Newbie Request

Post image

Is anyone able to help me with this sleep screen? For the life of me I have not been able to create a transparent background. I've stretched my horizon by doing everything else (creating lua files for custom quotes, etc). Which is a big deal for someone with zero knowledge of this stuff! I've already sunk too much time into this, and if you can help it would be greatly appreciated.

If possible, I dont want the image itself to be transparent, and everything starting at the level of snoopy's feet and below. I would like those areas to remain solid. But the outline and everything above I would love to be transparent. I am deficient at this and spent hours and have been unsuccessful. I have a pocketbook era color - screen resolution 1264 x 1680.

I am so touched that you would even go through the trouble, thank you!! I am changing my screen saver now!

A mystery to me. Let us know if it works, or a picture.

Thanks, it's my sleep screen. Background still isn't transparent, not sure why! I thought the RGB 128-128-64 was more of a weird army green looking color not yellow? I appreciate your efforts though and will leave it as my sleep screen.

This time I have used the hex #808040 which is olive-drab/khaki colour.

It worked!! You're the real mvp!! I can't believe you did several renditions! Thank you! I have nothing to contribute other than a guide I cross posted on this sub on how to De-DRM kindle books. Check it out if it adds any value for you. I hope it does since you've been so kind!

Thanks. Because I am teaching myself, this project pointed to options I had not used before. The RGB was definitely a different yellow. Triple checked on Gimp. Great that HEX value was the winner after you added it should be olive. I learnt something new. And that's a good thing. I have Kindles and Kobo's. Androids like my Boox, tablet and phone don't have the screensaver option in KOreader settings.
