🔠 十六进制转位图（HEX / C 数组 → BMP）Convert Hex to Bitmap

使用说明与常见问题How-to & FAQ

「十六进制转位图（HEX / C 数组 → BMP）」是什么？What is the Convert Hex to Bitmap tool?

把十六进制颜色网格或 C 数组画回位图：支持 #RRGGBB / RRGGBB 每行一排像素、0xRRGGBB 的 C 数组，以及按宽度自动折行。可指定宽度（留空 = 按行推断）和放大倍数，导出 24 位 BMP 或 PNG。适合把单片机点阵、LED 程序里的色值还原成图片，全部在浏览器本地完成。Paint a hex colour grid or C array back into a bitmap: #RRGGBB / RRGGBB with one pixel row per line, a C array of 0xRRGGBB values, or a flat list wrapped to a width you set (blank = infer from line breaks). Set a scale for viewing and export a 24-bit BMP or PNG. Handy for turning microcontroller or LED colour tables back into pictures; everything runs locally in your browser.

如何使用「十六进制转位图（HEX / C 数组 → BMP）」？How do I use the Convert Hex to Bitmap tool?

在「十六进制转位图（HEX / C 数组 → BMP）」中，按需设置「宽度（留空 = 自动）」、「放大倍数」、「格式」等选项，然后点击「下载」按钮即可。In the Convert Hex to Bitmap: Set "Width (blank = auto)", "Scale", "Format", then click "Download".

支持哪些写法？Which formats are accepted?

每行若干个 #RRGGBB 或 RRGGBB（空格 / 逗号分隔）会按行排成像素；也可以贴 C 语言里的 0xRRGGBB 列表，再填写宽度自动折行。#RGB 三位写法会扩展成六位；四位、五位等不完整写法会报错。和“位图转十六进制”导出的格式互相兼容。Several #RRGGBB or RRGGBB tokens per line (space or comma separated) become one pixel row; a C-style list of 0xRRGGBB values works too — set the width to wrap them. Three-digit #RGB is expanded to six digits; four- or five-digit tokens are rejected. It matches the formats from Convert Bitmap to Hex.

和“位图转十六进制”怎么配合？How does this work with Convert Bitmap to Hex?

先在“位图转十六进制”导出 #RRGGBB 网格或 C 数组，改几个色值后再粘贴回来，即可快速微调像素画或 LED 图案。Export a #RRGGBB grid or C array with Convert Bitmap to Hex, tweak a few values, paste them back here, and you can quickly edit pixel art or LED patterns.
