Day 2 - pixelart Gem - Mint Your Own Pixel Art Images Using Any Design (In ASCII Text) In Any Colors; Incl. 2X/4X/8X Zoom For Bigger Sizes

Written by geraldb Gerald Bauer

Paint by Numbers

Let’s use the mooncat design #0 (Standing·Smile·Solid·Left) in the original 21×17 pixel format in ascii text:

require 'pixelart'

pixels =<<PIXELS
0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 1 0 0
0 0 0 0 0 0 0 0 0 0 0 1 3 1 0 0 0 1 3 1 0
0 0 0 0 0 0 0 0 0 0 0 1 5 3 1 1 1 3 5 1 0
0 1 1 1 0 0 0 0 0 0 1 1 3 3 3 3 3 3 3 1 1
0 1 3 1 0 0 0 0 0 0 1 3 3 3 3 3 3 3 3 3 1
1 3 1 1 0 1 1 1 1 1 1 3 3 1 3 3 3 1 3 3 1
1 3 1 0 1 1 3 3 3 3 1 3 3 3 3 3 3 3 3 3 1
1 3 1 0 1 3 3 3 3 3 1 3 3 4 3 5 3 4 3 3 1
1 3 1 1 1 3 3 3 3 3 1 3 3 3 4 3 4 3 3 3 1
1 1 3 3 3 3 3 3 3 3 3 1 3 3 3 3 3 3 3 1 0
0 1 1 1 3 3 3 3 3 3 3 3 1 1 1 1 1 1 1 0 0
0 0 0 1 3 3 3 3 3 3 3 3 3 3 3 3 3 3 1 0 0
0 0 0 1 1 3 3 3 1 4 4 4 1 3 3 3 3 3 1 0 0
0 0 0 0 1 1 3 3 3 1 4 1 3 3 1 3 3 1 0 0 0
0 0 0 0 0 1 1 3 3 1 4 1 3 1 1 3 1 0 0 0 0

PIXELS

And let’s use the genesis white color scheme - super rare only 48 exist in the official MoonCatRescue blockchain contract state storage ;-):

colors = [
  '#555555',   # color 1
  '#d3d3d3',   # color 2
  '#ffffff',   # color 3
  '#aaaaaa',   # color 4
  '#ff9999'    # color 5
]

Note: The color 0 (transparent) is auto-magically added / defined.

And let’s mint a mooncat image:

img = Image.parse( pixels, colors: colors )
img.save( './i/mooncat_white.png' )

And let’s try a 3x zoom factor:

img3x = img.zoom( 3 )
img3x.save( './i/mooncat_white-3x.png' )

Voila!

Let’s change the colors to use the genesis black color scheme:

colors = [
  '#555555',   # color 1
  '#222222',   # color 2
  '#111111',   # color 3
  '#bbbbbb',   # color 4
  '#ff9999'    # color 5
]

And let’s start minting:

img = Image.parse( pixels, colors: colors )
img.save( './i/mooncat_black.png' )
img.zoom( 3 ).save( './i/mooncat_black-3x.png' )

Voila! Black is the new White!

Beyond Numbers - Yes, You Can - Use Your Own Pixel Color Shortcuts

Let’s use the Darth Vader pixel art originally designed by Aral Tasher in CSS. See the online demo »

Let’s cut-n-paste the pixel art matrix:

pixels = <<PIXELS

PIXELS

Note: Yes, you can use any number (e.g. 0 1 2 3 etc) or shortcut (e.g. o b ulg lg etc) for pixels. Only make sure you have a color map matching your shortcuts.

Let’s add the color map:

colors = {
   o:   'transparent',
   b:   '#1D191A',
   ulg: '#eaeaec',
   lg:  '#747474',
   db:  '#453C35',
   dg:  '#343031',
   w:   '#fff',
   r:   '#fc3435',
   blu: '#1F3A93',
   g:   '#00943b'
}

And let’s mint an imperial master image:

img = Image.parse( pixels, colors: colors )
img.save( './i/vader.png' )

And let’s try a 5x zoom factor:

img5x = img.zoom( 5 )
img5x.save( './i/vader5x.png' )

Voila!
