通过使用 Gimp 的菜单,您可以自动裁剪图像(去除白色边框)。我有很多不同大小的白色边框的图像。我想在命令行中使用 Gimp 删除它们,但我不知道命令是什么。
有人有想法吗?
也许可以使用 ImageMagick?
答案1
通过使用 ImageMagick:
convert -trim image.jpg image.jpg
要修剪/自动裁剪整个目录:
for a in *.jpg; do convert -trim "$a" "$a"; done
或者使用find
:
find -name "*.jpg" -exec convert -trim "{}" "{}" \;

我已经有一段时间没用过它了,但希望它能有所帮助。制作一个 gimp 批处理脚本(我将其命名为 crop-png.scm),并将其放在 ~/.gimp-2.6/scripts/ 中。
(define (crop-png filename)
(let*
(
(image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
(drawable (car (gimp-image-get-active-layer image)))
)
; crop the image
(plug-in-autocrop RUN-NONINTERACTIVE image drawable)
; save in original png format
(file-png-save RUN-NONINTERACTIVE image drawable filename filename
0 6 0 0 0 1 1)
; clean up the image
(gimp-image-delete image)
)
)
然后保存此 shell 脚本(例如 pngcrop.sh)并在 png 文件上调用它,如下所示:'pngcrop.sh *.png'
#!/bin/bash
if [ $# -le 0 ]; then
echo
echo "Usage: $(basename $0) file1.png [file2.png ...]"
echo
echo " This script uses gimp to autocrop PNG files and"
echo " save them to PNG format. You must have"
echo " crop-png.scm installed in your gimp "
echo " scripts directory."
echo
exit 1
fi
# set the filelist
files=$*
# # set the base command
# CMD="gimp -i -b "
# loop and add each file
for i in ${files[*]} ; do
# #echo $i
# ARGS="\"(crop-png \\\"$i\\\")\""
# CMD="$CMD $ARGS"
gimp -i -b "(crop-png \"$i\")" -b "(gimp-quit 0)"
done
# # add the end to quit
# TAIL="-b \"(gimp-quit 0)\""
# CMD="$CMD $TAIL"
#
# #echo $CMD
# eval $CMD
