"""检查 signed.docx 中签名图片对应的 drawing XML，看实际显示尺寸（EMU）。
|
||
|
||
目的:
|
||
字节已经证明一致（e2e_test.py），但用户仍看到"空白"。
|
||
本脚本读 document.xml，找到图片所在段落的:
|
||
- wp:extent (图片显示尺寸 EMU)
|
||
- 段落 pPr/spacing (line 行高)
|
||
- 段落所在表格单元格 tcW (单元格宽度)
|
||
对比图片实际像素 vs 显示尺寸 vs 段落行高，定位空白的视觉来源。
|
||
|
||
EMU 换算:
|
||
1 inch = 914400 EMU = 2.54 cm
|
||
1 cm = 360000 EMU
