Overview

PinePaper provides a built-in suite of generators and educational templates designed to replace proprietary coloring libraries (like Crayola or paid printables) with high-resolution, vector-crisp activity sheets.

Key features include:

  • On-Device AI Prompting: Type “a cartoon coloring page of an elephant” or “diwali celebration coloring sheet” to instantly create closed-path line art.
  • Print-Ready Vector Lines: Thick, crisp black contours (strokeWidth: 2–3px, #111111) with fillable interior paths optimized for home or classroom inkjet and laser printers (Letter & A4).
  • Interactive Bucket Fill (Desktop & Mobile Touch): One-tap fill for children on tablets, phones, or touchscreens, with built-in color palette swatches.
  • Multi-Page Coloring Book PDF Export: Stitch multiple scenes into a unified booklet with a personalized cover page, activity sheets, and a “Certificate of Coloring Mastery”.
  • Complementary Activity Generators: Connect-the-Dots and handwriting/letter tracing sheets themed around animals and cultural festivals.

Interactive Coloring Experience

One-Tap Bucket Fill on Mobile & Touch Devices

Every coloring sheet generated with drawColoringPage is constructed with enclosed sub-paths grouped under coloringPage.

  1. Selecting Colors:
    • At the bottom of each coloring page, a curated 5-swatch palette displays recommended shades (e.g., Savanna Gold, Festive Saffron, Forest Emerald).
    • Tapping or clicking any palette circle immediately activates that swatch color.
  2. Filling Regions:
    • Tap any enclosed section (ears, petals, sky, body, mane) to instantly flood-fill that specific vector path with the active color.
    • The fill tool automatically identifies the targeted zone without spilling over neighboring lines.
