在「数字列表转图片」中，按需设置「宽度（像素）」等选项，然后点击「生成」、「下载」按钮即可。In the Convert Numbers to Image: Set "Width (px)", then click "Generate", "Download".
数值如何映射？How are values mapped?
按列表中的最小值和最大值线性映射到 0-255 灰度（最小值为黑、最大值为白），可勾选反相；所有值都相同时全部画成黑色。Values are mapped linearly from the list's minimum (black) to its maximum (white) on a 0-255 greyscale; tick Invert to swap. If all values are equal, every pixel is black.
数字怎么分隔？逗号、1e3 和无效内容怎么处理？How are numbers separated? What about commas, 1e3 and invalid text?
用空格、换行、分号或逗号分隔。和「找最大数」等工具一致：像 1,000 这样符合千位分组的写法读作一个数（1000），结果下方会提示；1,2,3 这种不是千位分组的写法按逗号拆成几个数。支持小数、负号和 1e3 这样的指数写法。无法识别的内容（如 abc）或超出范围的值（如 1e400）会报错并指出是第几项，不会被悄悄忽略。Separate values with spaces, line breaks, semicolons or commas. As in Find Maximum Number and similar tools, a properly grouped value such as 1,000 is read as one number (1000) and a note below the result says so; something like 1,2,3, which is not thousands grouping, is split at the commas. Decimals, minus signs and exponent forms such as 1e3 are accepted. Text that is not a number (such as abc) or a value out of range (such as 1e400) gives an error naming the item instead of being skipped silently.
不足一行？Short last row?
末行缺的像素保持透明。Missing pixels on the last row stay transparent.
有哪些选项可以调整？What options can I adjust?
「数字列表转图片」的设置：「宽度（像素）」默认 8；可勾选：「反相」。每次生成结果都按当前设置处理。Settings in the Convert Numbers to Image — "Width (px)" default 8; tick boxes: "Invert". The result always uses the current settings.
