将批处理文件迁移到文件夹中

Question

I can shrink some images with imagemagick using mogrify in a batch file but I'm having trouble setting the destination directory

@ECHO OFF
SET scriptdir=%~dp0
cd /d %imagedir%
SET tb="thumbs"
IF NOT EXIST "%imagedir%"/%tb% MKDIR "%imagedir%"/%tb%
FOR %%a in (*.tif) do (
mogrify -resize 42x42 -format jpg -quality 100  %%a
move %%a %imagedir%/%tb%
)

The above script does what I want, but it's bugging me that I have to use move command to place the images there instead of creating them there.

Answer 1

Just add -path XYZ into your mogrify command to get ImageMagick to write the output files in directory XYZ . For example:

mkdir results
mogrify -path results -resize ... inputfile.jpg

The whole point of mogrify though is that you don't need a loop , you just do all the files in one go:

mogrify -path results -format jpg -resize 42x42 *.tif

Answer 2

Use option -write filename , documented as: write images to this file

mogrify -resize 42x42 -format jpg -quality 100 -write %imagedir%\%tb%\%%a %%a

I used %imagedir%\\%tb%\\%%a to fully specify an output filename, and I changed the slashes to Backslashes.
