Browsers cannot run PostScript, so an EPS without a preview needs a desktop tool first. Processed locally.
EPS 转 PNGEPS to PNG
导出 EPS 内嵌的预览图（TIFF 或 EPSI）为 PNG；文件实为 SVG 时直接栅格化。浏览器无法执行 PostScript，没有预览图的 EPS 需先用桌面工具转换。本地处理。Exports the preview image embedded in an EPS (TIFF or EPSI) as PNG, or rasterizes the file if it is actually SVG. Browsers cannot run PostScript, so an EPS without a preview needs a desktop tool first. Processed locally.
