KIMP - a (huge) WIP image/sprite editor for KnightOS

KIMP = KnightOS image manipulation program
I'm new to assembly (and anything calculator related) and decided to try and make a sprite editor for KnightOS. Eventually, it will support KnightOS's image format (and will also require me implementing 'kimg' support into the kernel d: ).

The source code is currently available here: https://github.com/maxleiter/kimp and any suggestions/comments/anything is appreciated.

Here's a quick screenshot

EDIT: Updated image with centered grid

Looks good so far. Glad that you got into calculator development.

My suggestions would be to move the sprite on the side and the menu further, so that when the menu is open, then we still see the sprite.

The menu is part of the KnightOS UI. The sprite grid seems to be off center though.

u/Max Leiter October 13, 2015, 08:01:55 PM

Centered the grid, looks a lot better. As streetwalrus said, I can't move the 'menu' atm.

For some reason the menu causes the kernel to crash if opened twice, and doesn't really work.

Sorry to hear about the crashes. Can you post the source in case people can help?

He already gave a link to the source

Hey, that's cool! Regarding the kernel crashes that could very well be related to KOS itself, as it's still a huge WIP in itself

The issue is definitely KIMP, as the same menu system is implemented in multiple other KOS apps (fileman, castle, etc)

If you can't figure it out, maybe ask SirCmpwn? (or anyone else in the KOS IRC channel)

I've asked multiple times lol, SirCmpwn didn't know (or didn't read it) and Ivoah said he'll help me look into it tomorrow. Other than that it seems like a weird bug. I've tried implementing it in 3 ways, once my own, once basically copied/pasted from Fileman, and one copied/pasted from Calcsys. All of them had basically the same issue, so I think the actual issue may be in another function

EDIT: Ivoah said he took a quick look over it today and didn't see anything wrong with it
EDIT 2: Mostly fixed, the issue was an extra pcall(flushKeys), https://github.com/MaxLeiter/KIMP/commit/fed46d979777c1cedfbb7f697a53a7ce4be7e0d3

Added a basic cursor, doesn't really like to work yet...

Any suggestions as to how to auto-generate the grid/cursor positions welcome, I have no idea as to how to go about doing it (i. e. input size, generate table)

u/Max Leiter October 17, 2015, 03:13:00 AM

Got the cursor to be functional, now to implement actual drawing

u/Dream of Omnimaga October 17, 2015, 04:10:26 AM

Good to hear. Also what software do you use to make screenshots by the way? I use CamStudio then VirtualDub, but I was curious if any other software could produce smaller GIF file sizes.

Also can your image editor edit grayscale sprites?

u/Max Leiter October 17, 2015, 04:20:09 AM

At the moment it has no saving, loading, or editing lol, but the idea is to support kimg (KnightOS's format), grayscale png, and whatever else there is in the calculator community.

I use ffmpeg with x11grab to record. The gif was made with imgur's video-to-gif thing.

u/Dream of Omnimaga October 17, 2015, 04:37:23 AM

If you support other formats than KOS, then Axe sprites (hexadecimal data) should probably be supported as well, since Axe is still used sometimes. You would just have to give the hexadecimal of the sprite data to the user so he can write it down. Of course, it's more for people who own two calculators or an emulator, but it could still be handy.

And I see. Thanks for the info about your video capture setup.
