== Code of Conduct
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as
|
||||
contributors and maintainers pledge to making participation in our project and
|
||||
our community a harassment-free experience for everyone, regardless of age, body
|
||||
size, disability, education, ethnicity, gender identity and expression, level of
|
||||
experience, nationality, personal appearance, race, religion, sex
|
||||
characteristics, sexual identity and orientation or socio-economic status.
|
||||
|
||||
=== Examples
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment
|
||||
include:
|
||||
|
||||
* Using welcoming and inclusive language.
|
||||
* Being respectful of differing viewpoints and experiences.
|
||||
* Gracefully accepting constructive criticism.
|
||||
* Focusing on what is best for the community.
|
||||
* Showing empathy towards other community members.
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or
|
||||
advances.
|
||||
* Trolling, insulting/derogatory comments, and personal attacks.
|
||||
* Public or private harassment.
|
||||
* Publishing others’ private information, such as a physical or electronic
|
||||
address, without explicit permission.
|
||||
|
||||
=== Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported by contacting the project team at {contact-coc}.
|
||||
|
||||
All complaints will be reviewed and investigated and will result in a response
|
||||
that is deemed necessary and appropriate to the circumstances. The project team
|
||||
is obligated to maintain confidentiality with regard to the reporter of an
|
||||
incident.
|
||||
|
||||
=== Attribution
|
||||
|
||||
This Code of Conduct is adapted from the Contributor Covenant, version 1.4,

== How to contribute
|
||||
|

Read the link:{uri-coc}[Code of Conduct].
|
||||
|
||||
=== Reporting bugs or suggesting enhancements
|
||||
|
||||
Before reporting a bug, please
|
||||
https://schlomp.space/tastytea/{project}/issues[perform a search] to see if the
|
||||
problem has already been reported. If it has, add a comment to the existing
|
||||
issue instead of opening a new one. Same for enhancements.
|
||||
|
||||
You can also contact me via mailto:{contact-email}[E-Mail],
|
||||
link:xmpp:{contact-xmpp}[XMPP] or the {contact-fediverse}[Fediverse] if you
|
||||
don't want to open an account.
|
||||
|
||||
=== Pull requests
|
||||
|
||||
Please use similar coding conventions as the rest of the project. The basic rule
|
||||
to remember is to write code in the same style as the existing/surrounding code.
|
||||
|
||||
You can also send me your patches via mailto:{contact-email}[E-Mail], ideally
|
||||
using `git format-patch` or `git send-email`.

*identiconpp* is a library to generate identicons for C++.
|
||||
|
||||
You get the images as `Magick::Image`. This allows you to make all kinds of
|
||||
modifications.
|
||||
|
||||
.Used algorithms, left to right: 4x4 ltr_symmetric, 20px padding; 5x5 sigil; 5x5 ltr_asymmetric; 6x4 ltr_symmetric, 10px padding

== Features

|
||||
* [x] Symmetric identicons
|

* [x] sigil identicons
|
||||
* [x] Asymmetric identicons
|
||||
* [x] Padding
|
||||
|
||||
== Usage
|
||||
|
||||
The HTML reference can be generated with `build_doc.sh`, if doxygen is
|
||||
installed. It is also available at
|
||||
link:{uri-reference-base}/classIdenticonpp.html[doc.schlomp.space/identiconpp/].
|
||||
|
||||
You need to generate hashes yourself, any hexadecimal string will do. Make sure
|
||||
to use a safe hashing algorithm for sensitive data (*not MD5*). You can select
|
||||
as many columns and rows as you like, but make sure you have enough entropy.
|
||||
If something seems to be wrong, exceptions will be thrown.
|
||||
|
||||
The "sigil" algorithm generates the same results as link:{uri-sigil}[sigil] and
|
||||
link:{uri-pydenticon}[pydenticon].
|
||||
|
||||
=== Example
|
||||
|
||||

|
||||
----
|
||||
// Compile with g++ $(pkg-config --libs --cflags identiconpp)
|
||||
#include <iostream>
|
||||
#include <identiconpp.hpp>
|
||||
#include <Magick++/Image.h>
|
||||
|
||||
int main()
|
||||
{
|
||||
Identiconpp identicon(5, 5, Identiconpp::algorithm::ltr_symmetric,
|
||||
"ffffff80", { "800000ff" }, { 10, 10 });
|
||||
Magick::Image img;
|
||||
img = identicon.generate("55502f40dc8b7c769880b10874abc9d0", 200);
|
||||
img.write("identicon.png");
|
||||
|
||||
std::cout << identicon.generate_base64("png", "5550", 200) << std::endl;

|
||||
link:{uri-pgpkey}[automatic signing key].
|
||||
|
||||
=== From source
|
||||
|
||||

== Algorithms
|
||||
|
||||
=== ltr_symmetric
|
||||
|
||||
* Create image with width=columns, height=rows.
|
||||
* Set background color.
|
||||
* Select half of the columns, or half of the columns + 1 if uneven.
|
||||
** `columns / 2 + columns % 2`
|
||||
* Pixels are drawn from left to right, top to bottom.
|
||||
* Use bits from digest to determine if a pixel is painted(1) or not(0).
|
||||
* Mirror the pixels vertically.
|
||||
* Use the following bits to pick the foreground color.
|
||||
** You need `floor(log2(n_colors)) + 1` bits.
|
||||
* Scale image proportionally to requested width.

## Usage
|
||||
|
||||
The HTML reference can be generated with `build_doc.sh`, if doxygen is
|
||||
installed. It is also available at [doc.schlomp.space/identiconpp/]
|
||||
(https://doc.schlomp.space/identiconpp/classIdenticonpp.html).
|
||||
|
||||
You need to generate hashes yourself, any hexadecimal string will do. Make sure
|
||||
to use a safe hashing algorithm for sensitive data (**not MD5**). You can select
|
||||
as many columns and rows as you like, but make sure you have enough entropy.
|
||||
If something seems to be wrong, exceptions will be thrown.
|
||||
|
||||
The "sigil" algorithm generates the same results as
|
||||
[sigil](https://github.com/cupcake/sigil/) and
|
||||
[pydenticon](https://github.com/azaghal/pydenticon/).
|
||||
|
||||
### Example
|
||||
|
||||
``` c++
|
||||
// Compile with g++ $(pkg-config --libs --cflags identiconpp)
|
||||
#include <iostream>
|
||||
#include <identiconpp.hpp>
|
||||
#include <Magick++/Image.h>
|
||||
|
||||
int main()
|
||||
{
|
||||
Identiconpp identicon(5, 5, Identiconpp::algorithm::ltr_symmetric,
|
||||
"ffffff80", { "800000ff" }, { 10, 10 });
|
||||
Magick::Image img;
|
||||
img = identicon.generate("55502f40dc8b7c769880b10874abc9d0", 200);
|
||||
img.write("identicon.png");
|
||||
|
||||
std::cout << identicon.generate_base64("png", "5550", 200) << std::endl;
|
||||
}
|
||||
```
|
||||
|
||||
## Install
|
||||
|
||||
### Gentoo
|
||||
|
||||
Gentoo ebuilds are available via my
|
||||
[repository](https://schlomp.space/tastytea/overlay).
|
||||
|
||||
### Automatically generated packages
|
||||
|
||||
Binary packages are generated automatically for each
|
||||
[release](https://schlomp.space/tastytea/identiconpp/releases) in the formats
|
||||
`deb` and `rpm`. They are signed with my [automatic signing
|
||||
key](https://tastytea.de/tastytea_autosign.asc).
|
||||
|
||||
### From source
|
||||
|
||||
#### Dependencies
|
||||
|
||||
* C++ compiler (tested: [gcc](https://gcc.gnu.org/) 6/8/9,
|
||||
[clang](https://llvm.org/) 7)
|
||||
* [cmake](https://cmake.org/) (at least 3.6)
|
||||
* [imagemagick](https://www.imagemagick.org/) (tested: 7.0 / 6.7)
|
||||
* Optional:
|
||||
* Tests: [Catch](https://github.com/catchorg/Catch2) (tested: 2.3 / 1.2)
|
||||
|
||||
On a Debian system, install the packages:
|
||||
`build-essential cmake libmagick++-dev`.
|
||||
|
||||
#### Compile
|
||||
|
||||
``` shell
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
make install
|
||||
```
|
||||
|
||||
##### cmake options
|
||||
|
||||
* `-DCMAKE_BUILD_TYPE=Debug` for a debug build
|
||||
* `-DWITH_TESTS=YES` to build tests
|
||||
* One of:
|
||||
* `-DWITH_DEB=YES` to generate a deb-package
|
||||
* `-DWITH_RPM=YES` to generate an rpm-package
|
||||
|
||||
To generate a binary package, execute `make package`

## Algorithms
|
||||
|
||||
### ltr_symmetric
|
||||
|
||||
* Create image with width=columns, height=rows.
|
||||
* Set background color.
|
||||
* Select half of the columns, or half of the columns + 1 if uneven.
|
||||
* `columns / 2 + columns % 2`
|
||||
* Pixels are drawn from left to right, top to bottom.
|
||||
* Use bits from digest to determine if a pixel is painted(1) or not(0).
|
||||
* Mirror the pixels vertically.
|
||||
* Use the following bits to pick the foreground color.
|
||||
* You need `floor(log2(n_colors)) + 1` bits.
|
||||
* Scale image proportionally to requested width.
|
||||
|
||||
