1) Use the arrow keys to select a background picture. * You can add your own pictures over the grid area. * Your pictures do not need to be pixellated! 2) Press <space> to scan. 3) Triple click on the 1LC list item to select it all, copy and paste the long text into the sprite costume name in one of the 1 Line Challenge projects below, then remix. - 1 Line Challenge Project with 1 fullsize picture: https://scratch.mit.edu/projects/701930009/ or https://scratch.mit.edu/projects/701936539/ or https://scratch.mit.edu/projects/701919706/ - 1 Line Challenge Project with 4 smaller pictures: https://scratch.mit.edu/projects/702001160/ - 1 Line Challenge Project with 4 rotated pictures: https://scratch.mit.edu/projects/702343648/ 4) That's all! The 1LC projects will draw the picture! Notes ===== - You can use any picture within the grid square. The scan does not go outside the grid square. - If you want an exact copy of an already pixellated picture, you should align that picture with the squares. How it Works ========== The scan samples the colours from a central pixel in each of the 10x10 squares of the 360x360 grid. The scan puts the 36x36 RGB colour values into a list. Then 10000000 is added to each RGB colour value to make them each 8 digits long. The 36x36 list of coded 8 digit colours is joined into 1 long data value. 36x36 pixels x 8 digits per pixel = 10,368 characters This is the long text value that you copy from the list. These 1 Line Challenge projects colour each 10x10 pixel square (of the 360x360 drawing area) using a decoded 8 digit colour from the data value. Decoding is simply subtracting 10000000. The 1 Line Challenge projects access the long text in the costume name 8 times for each pixel using the "letter ... of ..." block. The 8 digits are joined with "join" blocks before 10000000 is subtracted.
