Melpomene is a a simple, easy to integrate webcomic reading utility .
|
||||
Melpomene is a a simple, HTML/CSS/JS webcomic reading utility .
|
||||
|
||||
It allows people to look through your webcomic like they would in real life : panel by panel. It displays your pages through a series of zooms you defines beforehand.
|
||||
|
||||
Melpomene uses SVGs as input to defines the zooms. It allows you to use any SVG editor as a "What You See Is What You Get" editor.
|
||||
To avoid writing the zooms informations by hand, Melpomene utility scripts uses SVGs as input to defines the zooms. It allows you to use any SVG editor as a "What You See Is What You Get" editor.

# How Melpomene works
|
||||
|
||||
It works with :
|
||||
+ HTML, CSS and Javascript snipets you can put in your web page to add the webcomic reader
|
||||
+ A Javascript file describing the various informations required by the reader
|
||||
+ A Python script, used to generate the above Javascript configuration file
|
||||
|
||||
```mermaid
|
||||
flowchart TB
|
||||
page([Your comic pages]) -- use in --> svgedit[SVG editor<br>e.g. Inkscape, etc...]
|
||||
svgedit -- export --> svg([SVGs with<br>zooms defined])
|
||||
svg -- use in --> confgen[Melpomene<br>config generator]
|
||||
confgen --> conf([json<br>config])
|
||||
conf & html([HTML snipet]) & js([JS snipet]) & css([CSS snipet]) -- use / import into --> webpage([Your web page])
|
||||
svg -- use in --> gen[Melpomene<br>config generator]
|
||||
gen -- generate --> html([Melpomene HTML snipet])
|
||||
html -- copy into --> webpage([Your web page])
|
||||
js([melpomene.js]) & css([melpomene.css]) -- include into --> webpage
|
||||
```
|
||||
|
||||
Melpomene is mainly one JS file and one CSS file. You only need to include them in you web page. They are :
|
||||
+ `melpomene.js`
|
||||
+ `melpomene.css`
|
||||
|
||||
The JS files expect you to write some very specific HTML tags to be able to work.
|
||||
To simplify things, you only need to copy-paste the content of `melpomene.html` into your own page and change a few things :
|
||||
+ `data-pages-width` must be set to your comic pages width in px
|
||||
+ `data-pages-height` must be set to your comic pages height in px
|
||||
+ You must duplicate the `img` tag for each of you comic page and :
|
||||
+ set `url` to the actual URL of your page
|
||||
+ set `data-zooms` with the zooms information, like so : `<zoom 1 width>, <zoom 1 height>, <zoom 1 x offset>, <zoom 1 y offset>; <zoom 2 width> ...`
|
||||
+ example : `<img loading="lazy" src="https://www.peppercarrot.com/0_sources/ep35_The-Reflection/hi-res/en_Pepper-and-Carrot_by-David-Revoy_E35P01.jpg" data-zooms="2481.0,1327.1057,0.0,0.0;593.15338,1076.4635,0.0,1364.053;890.72864,491.29874,830.81415,1751.5;2481.0,1078.4192,0.0,1364.053;562.77032,909.44702,102.48115,2491.6567;920.74463,909.44702,698.55927,2491.6567;728.776,909.44702,1652.3695,2491.6567"/>`
|
||||
|
||||
Because doing this by hand would be very tedious, Melpomene comes with an helper script that allows generating that HTML for you from SVGs.

## Limitations

The following limitations are known and will be improved upon :

|
|||
3. Once you are done, save the SGV

|
||||
## Generating the configuration files
|
||||
## Generating the HTML files
|
||||
|
||||
Once the SVG for your pages are done, put them in one folder. Then, you can run the zoom generator.
|
||||
|
||||
You need to open a terminal and then run :
|
||||
+ `python zooms_generator.py <path to the SVG folder> zooms_data.json` on windows
|
||||
+ `python3 zooms_generator.py <path to the SVG folder> zooms_data.json` on linux
|
||||
+ `python zooms_generator.py <path to the SVG folder> html -p <prefix of the img's url> -e <extension of the img's url>`
|
||||
+ For example, if your comic pages are hosted at `static/comic/page_x.jpg`, the svg must be named `page_x.svg`
|
||||
and you must run `python zooms_generator.py <path to the SVG folder> html -p /static/comic/ -e jpg`
|
||||
+ It will generate the following `img` tag : `<img loading="lazy" src="static/comic/page_x.jpg" data-zooms="..."/>`
|
||||
|
||||
The pages need to be in alphabetical order! It assumes the first page is page 1, the next one is page 2, etc..
|
||||
|
||||
The script will then generate the file `zooms_data.json`.
|
||||
The script will then generate the file `melpomene_data.html`.
|
||||
|
||||
If you wish to run a custom generation process, this generator can output a JSON or a JS file as well, run `python zooms_generator.py -h` for help
|
||||
|
||||
You are now ready to integrate Melpomene in your website!
|
||||
|
||||
|
||||
## Integrating Melpomene
|
||||
|
||||
Let's assume your site is `https://my.website/`.
|
||||
|
||||
You now need :
|
||||
1. Host the Melpomene Javascript and CSS files in your website, e.g. at `https://my.website/melptomene.js` and `https://my.website/melptomene.css`
|
||||
2. Host the zooms data on your website, e.g. at `https://my.website/zooms_data.js`
|
||||
2. Include the various parts of the HTML snipets :
|
||||
1. `melpomene_head.html` goes in the `head` tag of your page
|
||||
* You may need to change the `href` values to where you uploaded the CSS file.
|
||||
2. `melpomene_reader.html` goes where you want somewhere within the `body` tag of your page
|
||||
* Change `data-pages-width` and `data-pages-height` with the actual width and height of your pages
|
||||
* Change `https://link.to.my/comic/page.jpg` to the actual URL of your comic pages and duplicate the `img`
|
||||
tag for each of them
|
||||
3. `melpomene_js.html` goes right after the `body` tag of your page.
|
||||
* You may need to change the `href` values to where you uploaded the JS files.
|
||||
|
||||
You can now open your page and should see the results.
|
||||
|
||||
If you are having troubles, you can open the demo files to see how it was done.
