Worked until 4.4.2.\n\n### snippet\n\n```processing\nPImage img;\n\nvoid setup() {\n  size(150, 150);\n  setupHexagon(50);\n  hexagon(75, 75, 50);\n}\n\nvoid draw() {\n}\n\nprivate void setupHexagon(int radius) {\n  noiseSeed(1004);\n  img = createImage(radius*2, radius*2, RGB);\n  for (int px = 0; px \u003c img.width; px++) {\n    for (int py = 0; py \u003c img.height; py++) {\n      float n = noise(px/(float)img.width, py/(float)img.height);\n      img.pixels[px+py*img.width] = color(n*255);\n    }\n  }\n  img.updatePixels();\n\n  PShape s = createShape();\n  s.beginShape();\n  s.fill(255);\n  for (int i=0; i\u003c6; i++)\n    s.vertex(cos(PI/3*i) * radius, sin(PI/3*i) * radius);\n  s.endShape(CLOSE);\n  PGraphics maskImage;\n  maskImage = createGraphics(img.width, img.height);\n  maskImage.beginDraw();\n  maskImage.shape(s, img.width/2., img.height/2.);\n  maskImage.endDraw();\n  img.mask(maskImage);\n}\n\nprivate void hexagon(float x, float y, float radius) {\n  imageMode(CENTER);\n  image(img, x, y, 2*radius, 2*radius);\n}\n```\n\n\n### Additional context\n\nSnippet draws a hexagon with noisy pattern.\n\n### Would you like to work on the issue?\n\nassign to someone else, please","author":{"url":"https://github.com/hkiel","@type":"Person","name":"hkiel"},"datePublished":"2025-04-28T14:25:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":16},"url":"https://github.com/1065/processing4/issues/1065"}
