Orange Pixels

Orange Pixels is a Generative ORC-721 project designed to give collector/creators the ability to create any 24x24 px 1 color image with a transparent background. Orange Pixels is an attempt to demonstrate one way on chain data can be used to generate more complex and customizable creations.

Is Orange Pixels Recursive?

By definition, the ORC-721 protocol is recursive since images are composed by referencing previously inscribed source data via the protocol. The protocol layers the source images from the spritesheet to create a composite. Minted pieces are JSON files that need rendered by an external process to be viewed as images.

The spritesheet is inscription #13069312

As with other methods of inscribing recursively, experimentation is required to allow ideas for maximum composability and customization to rise to the top, and there are many lines of thinking when it comes reading and rendering pre-inscribed data. I support experimentation with multiple methods for storing and referencing data on chain and taking what works best from all of them.

How Does Orange Pixels Work?

Orange pixels references a 576 tile spritesheet (24 x 24).

Each tile contains 1 colored pixel with a transparent background in a 24 x 24 grid.

Inscribers can use "g" values of 0 - 575 to represent any pixel position(s) in a 24 x 24 grid to create a 2 color composite image.

How to Create an Image

Following are 2 ways to generate the "g" values to will use to create an image, although it is easy to contceive others methods.

Method #1 - Use the painter created by @geraldb to generate a pre-designed or custom image

Open the painter
Upon load, one of the pre-designed images will randomly show in the pixel canvas. The "g" values for the image are shown below in the text box, see example:
To try a different random image, click the 'Try Random (Design)' button
To draw an image freehand, you can click individual pixels to select/desect them, or drag the cursor to select as you go. Once you are happy with your design, click the 'Print' button to generate the "g" values for your image.
There are additional, intuitive features of the painter than can be understood through use

Method #2 - Count colored pixels from a custom source image file

If you already have a 24 x 24 pixel file you want to recreate, use the count_pix.py script to generate a number string of colored pixels from the 24 x 24 px file. Note, the script will return a value for all colored pixels, so this method currently only supports silohuette style images.

I manually edited Ordinal Punk 01 below to create a 2 color image I liked (I messed up the nose):

Running the image through the count_pix.py script generates this string, which is a numbered list of every pixel containing a color value:

128, 129, 130, 131, 132, 133, 134, 151, 159, 174, 184, 198, 208, 222, 232, 246, 256, 270, 272, 273, 274, 275, 276, 277, 278, 279, 280, 293, 294, 296, 297, 299, 300, 301, 303, 304, 316, 317, 320, 321, 322, 323, 324, 325, 326, 327, 328, 341, 342, 344, 345, 346, 347, 350, 351, 352, 366, 376, 390, 393, 394, 395, 396, 397, 398, 399, 400, 414, 415, 416, 417, 418, 419, 420, 421, 422, 423, 424, 425, 437, 438, 439, 440, 441, 442, 446, 447, 448, 449, 461, 462, 463, 464, 465, 466, 467, 468, 469, 470, 471, 472, 473, 485, 486, 487, 488, 489, 490, 491, 492, 493, 494, 495, 496, 497, 510, 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, 534, 536, 537, 538, 539, 540, 541, 542, 543, 544, 558, 562, 563, 564, 565, 566, 567

The string can be used for the "g" values of a colleciton inscription, like this:

{
   "p":"orc-721",
   "op":"mint",
   "s":"orangepixels",
   "g":[128, 129, 130, 131, 132, 133, 134, 151, 159, 174, 184, 198, 208, 222, 232, 246, 256, 270, 272, 273, 274, 275, 276, 277, 278, 279, 280, 293, 294, 296, 297, 299, 300, 301, 303, 304, 316, 317, 320, 321, 322, 323, 324, 325, 326, 327, 328, 341, 342, 344, 345, 346, 347, 350, 351, 352, 366, 376, 390, 393, 394, 395, 396, 397, 398, 399, 400, 414, 415, 416, 417, 418, 419, 420, 421, 422, 423, 424, 425, 437, 438, 439, 440, 441, 442, 446, 447, 448, 449, 461, 462, 463, 464, 465, 466, 467, 468, 469, 470, 471, 472, 473, 485, 486, 487, 488, 489, 490, 491, 492, 493, 494, 495, 496, 497, 510, 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, 534, 536, 537, 538, 539, 540, 541, 542, 543, 544, 558, 562, 563, 564, 565, 566, 567]
}

Method #3 - Visit the Ordinal Punks discord Generative ORC-721 channel and we'll help you along!

Join the Ordinal Punks discord and visit the Generative ORC-721 channel (please keep the general chat channel clean!)
Post your best effort at a black and white/1-bit image to the discord, and I or @geraldb will convert the image to "g" values for you.

Once you have generated your "g" values using these or other methods, you can paste the values into the to generate.rb file which will use the spritesheet to recreate the image:

You can also paste the string of "g" values into the text box on the painter and click the 'Read' button to see your image.
