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

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

keyup on game data input sets palette to pal 0 even if game data has not changed

to do

allow user to save output as image, or tweet it :) user can currently right-click -> Save As but the 128x128 size is not great
create new tiles based on image
- only add unique new tiles
- don't write the 0 tile (implicit background-only tile)
implement slider (always use existing tiles -> always create new tiles) (representing 0-64 threshold for # of common pixels)
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

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
give heavier weighting to edge pixels when finding a matching tile? (thanks Mark)
