Pic2Tic

For the best experience, run the tool Here

*Due to itch.io's security policy, the copy/paste buttons do not work, by lack of clipboard api permissions within the iframe that itch runs your html5 in. This is because the javascript reads/writes text to the clipboard, in order to import palette's and copy sprite & pixel data (for TIC80 users) via a convenient button-press, instead of manual entry. The github page that runs the app however does not have this issue and works fine. Enjoy!

Lua Function for TIC-80:

function draw_image(x, y, width, height, pixel_data, color_key)
  color_key = color_key or -1
  for i = 0, width - 1 do
    for j = 0, height - 1 do
      local index = j * width + i
      if pixel_data[index] ~= color_key then
        pix(x + i, y + j, pixel_data[index])
      end
    end
  end

Note: This is a base function to assist in drawing images in TIC-80. Modify as per your needs!
