- 将图片生成流程从 latex -> dvips -> gs -> png 简化为 pdflatex -> pdf - 利用 Mogan 内置 MuPDF 直接渲染 PDF，不要求用户安装 Ghostscript - 添加 pdf-page-empty? 解析 pdflatex 日志检测空图形，保留提示文本 - 更新 init-tikz.scm 和 binary/tikz.scm 引入 pdflatex 支持 - 更新单元测试覆盖新的 image-valid? 和 pdf-page-empty?

file_flush 对 PDF 缺少原生尺寸回退，导致 width=0px&height=0px 时 image_flush 默认使用 0.618par，图片被拉伸到页面宽度的 61.8%。 修复：为 PDF 补充 image_size 检测，并将 pt 按 144 DPI 转换为像素 （px = pt * 144 / 72 = pt * 2），与旧 Ghostscript -r144 参数保持一致。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

- 新增 pdf-page-size 函数，从 pdflatex log 中解析 papersize= - 当用户未指定宽高时，eval-and-print 自动将 pt 换算为 px（144 DPI） - 移除对 src/Data/Convert/Generic/input.cpp 的修改需求 - 更新 pdf-page-empty? 复用 pdf-page-size - 更新单元测试覆盖 pdf-page-size 和 pdf-page-empty? Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
