「SVG 转 BMP」是什么？What is the SVG to BMP Converter tool?

把 SVG 矢量图批量转换为 24 位 BMP 位图：可指定输出宽度按比例缩放，透明处填充背景色，适合只认 BMP 的嵌入式屏幕取模、刺绣/雕刻软件和老系统，多张打包 ZIP，全部在浏览器本地完成。Batch-convert SVG vector graphics to 24-bit BMP bitmaps at the width you choose, with transparent areas filled — for embedded display tools, embroidery or engraving software and legacy systems that only read BMP. Download each file or a ZIP; everything runs locally.

如何使用「SVG 转 BMP」？How do I use the SVG to BMP Converter tool?

在「SVG 转 BMP」中，选择或拖入文件，按需设置「输出宽度（像素，留空为原始尺寸）」、「透明处背景色」等选项，然后点击「全部下载（ZIP）」按钮即可。In the SVG to BMP Converter: Choose or drop your files, set "Output width (px, blank = original size)", "Background for transparency", then click "Download all (ZIP)".

BMP 支持透明吗？背景是什么颜色？Does BMP keep transparency? What is the background?

输出的 24 位 BMP 不含透明通道，SVG 的透明部分会填充为「透明处背景色」（默认白色）。做单片机或 LCD 取模时，通常把背景设为白色或黑色，并把「输出宽度」设成屏幕的像素宽度。The 24-bit BMP has no alpha channel, so transparent parts of the SVG are filled with Background for transparency (white by default). For microcontroller or LCD bitmap tools, set the background to white or black and Output width to the screen's pixel width.

输出尺寸怎么定？How is the output size set?

默认按 SVG 自身的 width/height（支持 px、pt、mm、cm、in 等单位）输出；没有写尺寸时用 viewBox 的大小，两者都没有时按浏览器默认的 300 × 150。填写「输出宽度」可以按比例放大或缩小，矢量图放大后边缘依然清晰，最大 16384 像素。By default the SVG's own width/height is used (px, pt, mm, cm, in and other units are understood); without them the viewBox size is used, and with neither the browser default of 300 × 150. Set Output width to scale proportionally — vector art stays sharp when enlarged — up to 16,384 px.

哪些 SVG 内容可能显示不出来？What SVG content might not render?

转换时 SVG 按图片方式渲染：脚本和动画不会运行（只取初始画面），引用外部网址的图片和网络字体不会加载，文字会用本机已有的字体显示。需要准确的文字效果时，请先在设计软件里把文字转为路径。The SVG is rendered as an image: scripts and animations don't run (the initial frame is used), images and web fonts from external URLs are not loaded, and text uses fonts installed on your device. For exact typography, convert text to outlines in your design app first.

BMP 是什么格式？What kind of BMP is produced?

输出 24 位无压缩 BMP（Windows 位图），兼容几乎所有软件和老设备，但文件很大（宽 × 高 × 3 字节）；透明区域填充为背景色。An uncompressed 24-bit Windows bitmap that almost any software or legacy device can read, but large (width × height × 3 bytes); transparent areas are filled with the background color.

图片会上传吗？Are my images uploaded?

不会。解码和编码都在你的浏览器里完成，文件不会离开你的设备；照片中的 EXIF 元数据（包括拍摄位置）不会写入输出文件。No. Decoding and encoding happen in your browser and files never leave your device; EXIF metadata in photos (including location) is not written to the output.
