Overview

What is Dalted?

Web-app that simulates different types of color blindness from a user-provided input image.

Resources

The color blindness simulation implementation was inspired by Vienot et al., 1999.
This simulation is explained in this awesome post.
Back-end written in actix-web.
Backbone and guide for building a Rust-Web-App.

bug fix: updated the version of tiny-skia

When updated the version of tiny-skia package to the current master (0.4.2) the problem is fixed. It was in having multiple tiny-skia packages. (0.4.2) as a dependency and (0.3.0) from the Cargo.toml.

[Ticket: #6]

feat: provides an option that a different server:port can be passed into the code from the command line input argument
Issue description:

In my development environment, the default 8000 port was used by other application, and it requires me to modify the hardcode ADDR const variable from the code and recompile to get it working

I also need to deploy the binary to another environment (as part of my research work). Both the default host and port were not working, and I need to recompile code whenever to move the binary to another environment.

What was changed in this MR:

Keep the default server:port, as it is when the user runs the binary, is executed without an additional command-line argument.

If an additional command-line argument (server:port) is passed in when executing the binary, a user-specified server-port will be used to execute the binary.

Update the readme file to show users this new command-line option

When I compile the code from my Mac, the pre-check-in Cargo.lock file will cause a build issue with "Blocking waiting for file lock on the ...", this is due to the cached cargo.lock. Idea is we should not check in Cargo.lock to GitHub. I added Cargo.lock to .gitIgnore list to avoid polluting developers' own local environment.

chore(deps): bump regex from 1.5.4 to 1.5.6
Bumps regex from 1.5.4 to 1.5.6.

Changelog

Sourced from regex's changelog.

1.5.6 (2022-05-20)

This release includes a few bug fixes, including a bug that produced incorrect matches when a non-greedy ? operator was used.

[BUG #680](rust-lang/regex#680): Fixes a bug where [[:alnum:][:^ascii:]] dropped [:alnum:] from the class.

[BUG #859](rust-lang/regex#859): Fixes a bug where Hir::is_match_empty returned false for \b.

[BUG #862](rust-lang/regex#862): Fixes a bug where 'ab??' matches 'ab' instead of 'a' in 'ab'.

1.5.5 (2022-03-08)

This releases fixes a security bug in the regex compiler. This bug permits a vector for a denial-of-service attack in cases where the regex being compiled is untrusted. There are no known problems where the regex is itself trusted, including in cases of untrusted haystacks.

SECURITY #GHSA-m5pq-gvj9-9vr8: Fixes a bug in the regex compiler where empty sub-expressions subverted the existing mitigations in place to enforce a size limit on compiled regexes. The Rust Security Response WG published an advisory about this: https://groups.google.com/g/rustlang-security-announcements/c/NcNNL1Jq7Yw

build fail: tiny-skia update breaks some types

This is the error that is thrown:

For more information about this error, try `rustc --explain E0308`.

To learn more, run the command again with --verbose.

I looked into tiny-skia and the problem is with reexporting the struct in lib.rs probably.

Refactor: delegate linear algebra to ultraviolet

Description

Not having a custom R3 linear algebra implementation makes the source code easier to read. That gets the SLoC of the image processing part to 81.

Implementation

Replace everything under src/image_transformation/matrices.rs with ultraviolet.

Refactor: replace Rocket with actix-web

This Pull Request replaces the Rocket web framework with actix-web.

There is no real reason to do it, besides that I ended up changing the frontend while playing around with actix and it looks better now. The Rocket implementation will be kept in another branch.

refactor: use struct with matrix operations instead of raw array
Motivation

In order to use more chained matrix transformations, a better API should be implemented to apply matrix transformations and element wise operations.

Implementation

Change kernel from an alias type to a proper struct with matrix operations.

Progress

[x] working locally.

[x] tests implemented.

[x] implement also Mul for Kernel -> Kernel (not needed for the current transformations).
