🖼️ 论文多图拼版（自动加 a/b/c 标签，按期刊尺寸与 DPI 导出）Figure Panel Composer (a/b/c Labels, Journal Width & DPI)
把多张子图拼成论文用的组图：按列数自动排版（每行等高或等大格子），自动添加 a、b、c / A、B、C / (a)(b)(c) 标签（字号以 pt 计、可加粗），按 Nature、Cell、IEEE、Elsevier 的单栏/双栏宽度或自定义毫米宽度和 300/600/1000 DPI 导出 PNG、JPG 或 TIFF，并提示分辨率不足的子图。Combine sub-figures into one publication figure: automatic layout by columns (equal row height or equal cells), a/b/c, A/B/C or (a)(b)(c) labels in points (bold optional), and export PNG, JPG or TIFF at Nature, Cell, IEEE or Elsevier single/double-column widths (or custom mm) and 300/600/1000 DPI, with warnings for sub-figures lacking resolution.
导出图片的像素尺寸 = 版面宽度 × DPI，并写入 DPI 元数据，投稿系统会按物理尺寸识别。标签字号以 pt 计（Nature 要求 8 pt 粗体小写 a、b、c；Cell 使用大写 A、B、C）。子图分辨率不足时会提示，需要时请先放大原图或重新导出矢量图。Pixel size = layout width × DPI, with DPI written into the file so submission systems read the physical size. Label size is in points (Nature: 8 pt bold lowercase a, b, c; Cell uses uppercase A, B, C). You will be warned if a sub-figure lacks resolution.

「论文多图拼版（自动加 a/b/c 标签，按期刊尺寸与 DPI 导出）」是什么？What is the Figure Panel Composer (a/b/c Labels, Journal Width & DPI)?
把多张子图拼成论文用的组图：按列数自动排版（每行等高或等大格子），自动添加 a、b、c / A、B、C / (a)(b)(c) 标签（字号以 pt 计、可加粗），按 Nature、Cell、IEEE、Elsevier 的单栏/双栏宽度或自定义毫米宽度和 300/600/1000 DPI 导出 PNG、JPG 或 TIFF，并提示分辨率不足的子图。Combine sub-figures into one publication figure: automatic layout by columns (equal row height or equal cells), a/b/c, A/B/C or (a)(b)(c) labels in points (bold optional), and export PNG, JPG or TIFF at Nature, Cell, IEEE or Elsevier single/double-column widths (or custom mm) and 300/600/1000 DPI, with warnings for sub-figures lacking resolution.
如何使用「论文多图拼版（自动加 a/b/c 标签，按期刊尺寸与 DPI 导出）」？How do I use the Figure Panel Composer (a/b/c Labels, Journal Width & DPI)?
拖入或粘贴子图，拖动缩略图调整顺序；选择期刊版面宽度、列数、DPI 和标签样式，预览实时更新。下方显示导出像素和物理尺寸，确认后下载 PNG、JPG 或 TIFF。Drop or paste sub-figures and drag thumbnails to reorder. Choose the journal width, columns, DPI and label style; the preview updates live and shows export pixels and physical size. Then download PNG, JPG or TIFF.
期刊要求的图片宽度是多少？What widths do journals require?
Nature 单栏 89 mm、双栏 183 mm；Cell 单栏 85 mm、全宽 174 mm；IEEE 单栏 3.5 英寸、双栏 7.16 英寸；Elsevier 单栏 90 mm、全宽 190 mm。线条图通常要求 600–1000 DPI，照片 300 DPI。Nature: 89 mm single, 183 mm double column; Cell: 85 / 174 mm; IEEE: 3.5 / 7.16 in; Elsevier: 90 / 190 mm. Line art usually needs 600–1000 DPI, photos 300 DPI.
提示“子图有效分辨率不足”是什么意思？What does “below target DPI” mean?
子图被放大后，其原始像素不足以在目标 DPI 下覆盖所占区域，打印时可能模糊。请从绘图软件以更高分辨率或矢量格式重新导出该子图。The sub-figure has fewer pixels than its printed area needs at the target DPI, so it may print blurry. Re-export it from your plotting software at higher resolution or as vector art.
