# bitsy image to room

## about

a tool for Bitsy. upload any image and convert it into a room.
the room will be added to the game data automatically and you can paste it back into Bitsy.

## thanks

to **Adam LeDoux** for creating the wonderful and inspiring Bitsy

to **J.P. LeBreton** for creating Playscii which was a huge inspiration for this tool

to **Mark Wonnacott** for being relentlessly encouraging and making me want to work even an eighth as hard as them

to **Foliotek** for the **Croppie** image plugin

## contributing

The stylesheet and html are autogenerated; if you want to alter them please edit the pug template or less stylesheet, e.g. from the command line as follows:

`pug index.pug index.html`

`lessc style.less style.css`

`pug` and `less` can be installed via `npm` as follows:

`npm install -g pug-cli`

`npm install -g less`

I had to hack the included Croppie plugin to allow the user to upload images from their own computer without falling foul of CORS restrictions. So the version bundled here is non-standard. It's a one-line change:

```
croppie.js:182 (original)
if (src.match(/^(https)?:\/\/|^\/\//)) {
croppie.js:182 (mine)
if (src.match(/^(file|https)?:\/\/|^\/\//)) {
```

## known bugs

* palette selection sometimes stops working

## to do

* write Bitsy data
* rename save button ("write to game"?)
* allow user to save output as image, or tweet it :)
* create new tiles based on image
* only add unique new tiles
* implement slider (*always use existing tiles* -> *always create new tiles*) (representing 0-64 threshold for # of common pixels)
* move includes to subdirectory
* re-style the damn thing
* reorganise the page layout for a more logical workflow
* handle animated tiles?
* profile script performance and optimise where most needed
* make brightness slider trigger redraw every so often while being dragged, instead of waiting until drag stop
* add contact details and link to github

## could do

* add some more palettes?
* add some alternate default tiles? something more useful e.g. dithered gradients?
* add dithering options
* add camera support so users can take a pic instead of uploading an image
* add a 'smoothing' stage to remove errant pixels
* allow user to add palettes to game data
* allow user to draw to canvas
* do a 'branching tree' approach to finding the closest tile? i.e. create a 1x1, 2x2, 4x4 version of each tile, so all the broadly darker tiles will sit under '0' and lighter tiles under '1', then tiles that are lighter at the top will sit under '1100', etc... I'm not sure how much more effective this will be or whatever it will give better/faster results but it's worth a try
