Image-sequencer: New Module Ideas For Image Sequencer

[harshkhandeparkar]

Hello everyone! Do you have any good module ideas for image-sequencer?

Note: Modules with real world use cases which are to be added to IS are discussed in #707

Note: Some general module ideas are listed in #165

Ideas

If you have seen or heard of image processing steps even if you don't know what they mean or how they are different from others or if you know some great links where such reliable information can be found, then please let us know in the comments below.

If you have ideas for new modules(even original ones) and you don't know how to implement them, then you can open a new issue for it or let us know in the comments below.

If you know about some module and know how to implement it in the codebase, then please feel free to open a PR.

If you don't have any original idea then you can try implementing one of these.

Thank you!

I'm already working on a flip image module.

Flip image module done! https://github.com/publiclab/image-sequencer/pull/696

We have an old issue open for a text overlay module - a challenge because
without the canvas element, it means somehow parsing fonts! But there are
some npm modules we collected to research. Let's dig up the old issue link!

How about a tint module, that could tint with a color...

...or a levels module that can modify the brightness histogram, as in some
image editors... we can find a gif I'm sure to illustrate this...

@jywarren yes, I was coding the text overlay module and one possibility could be to parse/create a canvas with the text font and then use the logic of the image overlay module to overlap the transparent text canvas and the input image. I'll post some packages I think will be useful, did you by any chance come across any?

[Mridul97]

The idea of a tint module seems interesting, I would like to work on this one! @jywarren

[harshkhandeparkar]

@jywarren @publiclab/is-reviewers there was an old issue about a module which can remove a specific color. I have an idea about how that can be done but I'm not sure.

The module can go through all of the pixels and search for the provided color (maybe with some tolerance). If the color is found then replace it with the average of all four adjacent pixels.

@Mridul97 @VibhorCodecianGupta any thoughts? Or would you like to work on this?

The issue:

[harshkhandeparkar]

If nobody else wants to work on it the. i can try. I'll require a sample image though. @jywarren?

[Mridul97]

@HarshKhandeparkar Sounds good! would like to work on this, but I think we should wait for @jywarren thoughts on filling the pixel with average of adjacent pixels! Thanks!

[jywarren]

Hmm, interesting! Maybe we could replace with a greyscale pixel by
averaging the color channels for that pixel?

I want to mention some ideas from an old issue that could be consolidated into this one, maybe?

https://github.com/publiclab/image-sequencer/issues/165

[jywarren]

And @VibhorCodecianGupta maybe check out this fontpath module here? https://github.com/publiclab/image-sequencer/issues/431

it may allow us to avoid canvas although if we can get a good pure JavaScript version of canvas running, or otherwise make it simple to support for both node and browser, we could go that way too.

[jywarren]

Ah, also - threshold! I started here but never finished! https://github.com/publiclab/image-sequencer/pull/123

[aashna27]

I would like to work on the threshold module, if you don't mind @jywarren .

[Divy123]

@aashna27 maybe we can collaborate.
Also if you can help me with
https://github.com/publiclab/image-sequencer/issues/542

[aashna27]

@aashna27 maybe we can collaborate.

Yeah sure we can divide among the categories, I ll get back to you after some research.

[harshithpabbati]

We can have these special effects
Glow
Noise
Color matrix
HDR
@publiclab/is-reviewers what do you think about it???

[harshkhandeparkar]

Can you please explain those SFX?

[harshkhandeparkar]

@jywarren can we pin this issue so that everybody can discuss?

[harshkhandeparkar]

Some module ideas in #165

[harshkhandeparkar]

Temporarily unpinning this to pin the check-in

[blurry-x-face]

Unpinned the check-in to pin this issue as check-in is shifted to another repository.
