可打印数字油画生成器
将任何参考图像转换为专业的黑白数字油画模板，包含清晰的轮廓、编号区域和颜色图例。
Create a professional high-resolution paint-by-numbers template from the provided image as a single PNG only. Use an {argument name="canvas size" default="A4 portrait ratio canvas"} at 300 DPI with a pure white background. The main artwork must be a clean black-and-white line drawing containing only black outlines, black numbers, and white unfilled paintable areas. Do not create a PDF, document, mockup, multi-page layout, or colored version. Do not use color, gray, shading, texture, gradients, transparency, or pre-filled areas in the main artwork.
Analyze the original image and choose the number of colors adaptively based on image complexity, from 1 to a maximum of {argument name="color count" default="14 colors"}. If the image has only 1–2 important colors, use only 1–2 colors; for simple images use 3–6 colors; for medium complexity use 7–10 colors; for complex, photographic, or highly detailed images use 11–14 colors. Do not force unnecessary colors. Assign each selected color one unique number and merge similar shades unless separation is essential for recognition.
Convert the image into simplified, fully closed, easy-to-paint regions while preserving the recognizable composition, main objects, characters, text, logos, foreground, background, and key details. Every paintable white region must contain the correct black number, centered clearly inside the matching area, readable, upright, and not touching outlines. Large black or dark areas from the original must remain white paintable regions with the correct number, not filled black. Only tiny permanent black line details, such as mouth lines, nostrils, pupils, eyelashes, seams, or small decorative strokes, may remain unnumbered.
At the bottom of the same PNG, add a neat legend section with the heading “Instructions”, the sentence “Paint the areas with the matching colors.”, and a list of every used number with a small color swatch and the English color name. Color swatches may appear only in the legend. Ensure the numbering exactly matches the legend, every paintable area is numbered, all regions are closed, and the final result is clean, professional, print-ready, and recognizable as the original image. 将提供的图像转换为专业的单张高分辨率 PNG 格式数字油画模板。请使用 {argument name="canvas size" default="A4 纵向比例画布"}，分辨率为 300 DPI，背景为纯白色。主体艺术作品必须是清晰的黑白线条画，仅包含黑色轮廓、黑色数字和白色未填充的可涂色区域。请勿创建 PDF、文档、样机、多页布局或彩色版本。主体艺术作品中不得使用颜色、灰色、阴影、纹理、渐变、透明度或预填充区域。
分析原始图像，并根据图像复杂度自适应选择颜色数量，范围从 1 种到最多 {argument name="color count" default="14 种颜色"}。如果图像仅有 1-2 种重要颜色，则仅使用 1-2 种；简单图像使用 3-6 种；中等复杂度使用 7-10 种；复杂、摄影类或高度详细的图像使用 11-14 种。不要强行使用不必要的颜色。为每种选定的颜色分配一个唯一的数字，除非为了识别必须区分，否则请合并相似的色调。
将图像转换为简化、完全闭合且易于涂色的区域，同时保留可识别的构图、主体对象、角色、文本、徽标、前景、背景和关键细节。每个可涂色的白色区域必须包含正确的黑色数字，数字需清晰居中于匹配区域内，且易于阅读、正向放置且不接触轮廓。原始图像中的大面积黑色或深色区域必须保留为带有正确数字的白色可涂色区域，而不是填充为黑色。仅微小的永久性黑色线条细节（如嘴部线条、鼻孔、瞳孔、睫毛、接缝或小型装饰笔触）可以保持无编号状态。
在同一张 PNG 的底部，添加一个整洁的图例部分，标题为“Instructions”，正文为“Paint the areas with the matching colors.”，并列出每个使用的数字及其对应的小色块和英文颜色名称。色块仅可出现在图例中。确保编号与图例完全匹配，每个可涂色区域均已编号，所有区域均已闭合，最终结果应整洁、专业、适合打印，并能清晰识别出原始图像。
