ImageMagick，Bash脚本用注释和图像序列号标记

问题描述

我想为70张照片设置一张联系表。

I would like to have a set contact sheets for 70 photos.

而且，每张照片都与此标签类似：

And, each photo would have similar to this label:

n Comment

其中n表示图片编号。

我的Bash脚本正确显示评论。对于图像序列号，我很困惑。

My Bash script correctly shows the comment. For the image sequence number I am puzzled.

#!/bin/bash

/usr/bin/montage \
  -monitor  \
  -tile '3X3' \
  -label [useless attempts to number images]  %c \
  '/tmp/*-thumb.jpg' \
  ~/Desktop/SE-%d.jpg

我尝试了各种 fx：表达式和百分比转义结构，结果没有显示或数字为零
（，）。

I have tried various fx: expressions and percent escapes constructs with results either nothing displayed or the numeral zero(http://www.imagemagick.org/script/fx.php, http://imagemagick.org/script/escape.php).

推荐答案

我会这样做，使用MIFF将单独标记的文件附加到输出流，然后将它们全部从 stdin 读入蒙太奇命令：

I would do it something like this, using a MIFF to append individually labelled files to an output stream then read them all from stdin into the montage command:

#!/bin/bash
i=0
for f in /tmp/*-thumb.jpg; do
  convert -label "$i Comment %f" "$f" miff:-
  ((i++))
done | montage -       \
   -frame 5            \
   -tile 3x3           \
   -geometry +10+10    \
   -background black   \
   ~/Desktop/TheAnswer.jpg

它们看起来像这样：
