Script to draw a pixel at given coordinates

Hi,

I am not a script writer but I tried your query in ChatGPT which has created some very basic functions for me in other apps successfully, whilst I do believe an actual script writer will get it done more accurately, here is the result.

// Photoshop Script: Progressive Black Pixel Effect
#target photoshop

// Define dimensions and pixel increment
const layerWidth = 1943;
const layerHeight = 194;
const pixelsPerRowStart = 10; // Start with 10 pixels in the first row

// Create a new document
app.documents.add(layerWidth, layerHeight, 72, "Progressive Black Pixels", NewDocumentMode.RGB);

// Fill the background with white
const doc = app.activeDocument;
doc.artLayers.add();
const whiteLayer = doc.artLayers[0];
app.activeDocument.selection.selectAll();
app.activeDocument.selection.fill(app.foregroundColor);

// Ensure the black color is selected
const black = new SolidColor();
black.rgb.red = 0;
black.rgb.green = 0;
black.rgb.blue = 0;
app.foregroundColor = black;

// Function to draw a single pixel
function drawPixel(x, y) {
doc.selection.select([[x, y], [x + 1, y], [x + 1, y + 1], [x, y + 1]]);
doc.selection.fill(app.foregroundColor);
doc.selection.deselect();
}

// Generate and draw black pixels
for (let y = 0; y < layerHeight; y++) {
const pixelsThisRow = pixelsPerRowStart + y * 10; // Incremental increase in pixels
const xPositions = new Set();

// Ensure unique X positions for this row
while (xPositions.size < pixelsThisRow) {
const randomX = Math.floor(Math.random() * layerWidth);
xPositions.add(randomX);
}

// Draw black pixels for the current row
xPositions.forEach(x => drawPixel(x, y));
}

alert("Script finished! Check the created document.");

You would need to copy the above and save as a .jsx, then go to PS, File > Scripts > Browse and open the file you save.

NB I noticed I missed one value in the example, but it's just to illustrate so not to consider more than that.
