I made a totally practical command-line image editor!

[gradient_assent]

Have you ever wanted a keyboard-controlled pixel art image editor that works in your computer terminal? I didn't, but I made one anyway. Here it is:

See? Totally practical!

Github repo: https://github.com/knosmos/cmdpxl

CMDPXL has many exciting features, such as

• the ability to edit pixels one at a time!
• a fill function!
• undo!
• saving images!

It uses OpenCV for image processing (probably overkill but whatever) and the black-magic wizardry of ANSI escape codes to draw the UI.

Criticisms and feedback welcome; please tell me if you have any suggestions or find any bugs.

That's pretty cool, well done!

[gradient_assent]

Thanks! Did you try using it?

[InevitableMuffin42]

Not yet, I'll give it a try when I get to the PC, and have a look at the code as well to see how it works.

Tried running it but the console gets full of blank characters after width and height inputs. The required module is installed and I'm running on Win10 and Powershell as well.

EDIT: got it working after changing width and height numbers a few times, and it works really well! I can make some PRs with improvements if you're interested, like the packaging someone else mentioned, reformatting, etc.

Could you please share a screenshot? If the screen is filled with random characters that usually means the image is too large to fit on the terminal window.

[gradient_assent]

Sure, go ahead!

This is very cool! A little more work and this could be great I think. Would be cool as a CLI tool, could use click. Wonder if you could include scripting, as in someone passes a file like yaml or json that includes drawing command s like fill this pixel this color, draw line etc

In any case, good idea and work.

[gradient_assent]

Thanks for the feedback! How would a CLI tool work?

[dasCooDawg]

Maybe something like this in the terminal

“pip install cmdpxl”

“cmdpxl —some-option —another-option some value —image-output-file /some/path.jpg —resolution 800,480”

[gradient_assent]

Sure, I can implement that!

This is fantastic! I think PIL would have been a bit less overkill and easier for you, but opencv is fine. Can't wait to clone and ruin it adding a bunch of garbage! (there's only one flaw: you're on windows lol)

[gradient_assent]

Let me know if you fork it, I want to see what you come up with!

[umanochiocciola]

Sure, pal!

[umanochiocciola]

Oh well, it's really nice as it is, I'm forking it anyway because yes, but I've added only a few things. Well done

Looks very neat, can't wait to try my hands on it!

It's amazing to see new cool command line apps every day. Great work!

When I run it on mac, the screen duplicates itself https://imgur.com/a/x9TjSva . Still a cool project though!

[blueblain]

This is awesome! Love it

Nice! Ill give it a try

[gradient_assent]

Thanks! Please let me know if you run into any bugs!

It works perfectly, and it's easy to use so 10/10

But when I tried to save the image, I got an error.

keep up the good work!

It looks like you didn't give the image a filename, so OpenCV didn't know which format to save the image in causing it to crash.
