You should be able to use composite, but then you cannot use -draw. But composite can composite one image over another with dissolve. Did you try your command?

You can overwrite files. Did you try it?

I have no idea why you get and error with (8).jpg

Some OS systems do not like special ...

Sorry I missed something in your command. The input images must come first. You were using mogrify syntax with convert and that will not work. I have fixed that error and improved it to skip directories when looking for files (as long as the file has period in it). The following works fine for me ...

[root@localhost tempL]# du -k "/mnt/hgfs/L/BaiduYunDownload/tempL/temppic/2016.02.22 [정홍빛은유혹] 분2 68G/test (2).jpg"
0 /mnt/hgfs/L/BaiduYunDownload/tempL/temppic/2016.02.22 [정홍빛은유혹] 분2 68G/test (2).jpg
[root@localhost tempL]#

According to your script this file wouldn't be processed because

du -k ...

[root@localhost tempL]# du -k "/mnt/hgfs/L/BaiduYunDownload/tempL/temppic/2016.02.22 [정홍빛은유혹] 분2 68G/test (2).jpg"
0 /mnt/hgfs/L/BaiduYunDownload/tempL/temppic/2016.02.22 [정홍빛은유혹] 분2 68G/test (2).jpg
[root@localhost tempL]#

to the file mentioned by Fred:

Code: Select all

du -k "your test file here"

What do you get?

sorry, i do not know how to chage, can you provide entire code for me to test, my English is poor, thanks

Yes, I would agree. I overlooked the fact that $each needs to be quoted also.

#!/bin/bash
for each in "$(find /mnt/hgfs/L/BaiduYunDownload/tempL/temppic/* -type f -name '*.jpg')"
do
s=`du -k "$each" | awk '{print $1}'`
if [ $s -gt 10 ]; then
convert -resize 766 -quality 75 "$each" "$each ...

thanks for your help, but still can not work

below is my test code and result

file path:
/mnt/hgfs/L/BaiduYunDownload/tempL/temppic/2016.02.22 [정홍빛은유혹] 분2 68G/test (2).jpg

You could use the unix command 'find' to traverse all folders and subfolders.
Provided your pictures are all jpg, something like that will list all the jpg files
found in the top directory /mnt/hgfs/L/tempL and its subfolders:


#!/bin/bash

find /mnt/hgfs/L/tempL/* -type f -name '*.jpg' | while ...

so how to write in one script, i am new to bash command, can you help me, thanks

yes, so how to scripting in bash, i can process all pics, includes sub folders thanks,

Your code is already scripting in bash. It starts with

#!/bin/bash

and does its looping in bash. Only the convert and composite commands are Imagemagick.

thanks, but it only process root folder TempL, do ...

can you help me, i am new to imagemagick, i do not how to do a pipe, can you help me write, thanks

Your code already has a pipe.

convert /mnt/hgfs/L/tempL/rotate_330_614.png -fill grey50 -colorize 40 miff:- | composite -dissolve 8 -tile - $each $each 2>/dev/null

The pipe is the | symbol ...

That question is about scripting in bash, not about ImageMagick.

yes, so how to scripting in bash, i can process all pics, includes sub folders thanks,

As far as I know, Imagemagick does not traverse subdirectories. So you need to script finding each subdirectory and processing each image in the subdirectory.

Proper IM syntax reads the input image before processing such as -resize.

If you use the convert syntax for dissolve rather than ...

dear everyone

I use this to watermark pics in one folders with tile

#!/bin/bash
for each in /mnt/hgfs/L/tempL/*.jpg
do
s=`du -k $each | awk '{print $1}'`
if [ $s -gt 10 ]; then
convert -resize 1766 -quality 75 $each $each
convert /mnt/hgfs/L/tempL/rotate_330_614.png -fill grey50 -colorize 40 ...

The trick is to create logofuli.png at whatever size you need for the output, containing whatever image you need repeating.

thanks for your reply

I mean the logofuli.png is a fixed png file, how to add some parameter into this command
composite -tile -gravity center logofuli.png myg182_01.jpg ...
