如何使用批处理脚本评估文件夹中的每个文件

我在批处理脚本中使用imagemagick来评估jpg和png文件的文件夹。我想检查每个图像的打印尺寸,如果它符合我指定的标准,则输出到文本文件。我的代码不符合我的要求。它会将所有数据输出到文本文件,但前提是文件夹中的每个图像都符合正确大小的条件。我想要它来评估每个单独的图像。目前,如果有1个图像不在标准范围内,则不会将任何内容写入文本文件。

@echo off

REM %f - filename
REM %[size] - original size of image
REM %W - page width
REM %[resolution.x] - X density (resolution) without units
REM %H - page height
REM %[resolution.y] - Y density (resolution) without units
REM \n - newline
REM 1 in = 0.393701 cm - for PNG cm to in conversion

set output="C:\Documents and Settings\mfishm000\Desktop\Image_size.txt"

echo File_name:Size:Width:Height > %output%

REM set width as variable
FOR /F %%x IN ('identify -format "%%[fx:W/resolution.x]" *.jpg') DO SET width=%%x
FOR /F %%x IN ('identify -format "%%[fx:W/resolution.x*0.393701]" *.png') DO SET width=%%x

REM set height as variable
FOR /F %%y IN ('identify -format "%%[fx:H/resolution.y]" *.jpg') DO SET height=%%y 
FOR /F %%y IN ('identify -format "%%[fx:H/resolution.y*0.393701]" *.png') DO SET height=%%y

REM check if width is less than 8.67 and height is less than 11.22. If yes then output them to txt file
IF %width% LSS 8.67 (
    IF %height% LSS 11.22 (
        identify -format "%%f:%%[size]:%%[fx:W/resolution.x]:%%[fx:H/resolution.y]\n" *.jpg >> %output%
        identify -format "%%f:%%[size]:%%[fx:W/resolution.x*0.393701]:%%[fx:H/resolution.y*0.393701]\n" *.png >> %output%
    )
)

认为问题是您需要单独处理每个文件。好像最终只处理了最后一个文件的一个宽度/高度值。没有经过测试,但这应该可行。

    @ECHO OFF

    REM %f - filename
    REM %[size] - original size of image
    REM %W - page width
    REM %[resolution.x] - X density (resolution) without units
    REM %H - page height
    REM %[resolution.y] - Y density (resolution) without units
    REM \n - newline
    REM 1 in = 0.393701 cm - for PNG cm to in conversion

    set output="C:\Documents and Settings\mfishm000\Desktop\Image_size.txt"

    echo File_name:Size:Width:Height > %output%


    for /f %%a in ('dir /b ^| find ".jpg"') do call :processA "%%~a"
    for /f %%a in ('dir /b ^| find ".png"') do call :processB "%%~a"

    exit /B

    :processA
        FOR /F %%x IN ('identify -format "%%[fx:W/resolution.x]" %1') DO SET width=%%x
        FOR /F %%y IN ('identify -format "%%[fx:H/resolution.y]" %1') DO SET height=%%y
        IF %width% LSS 8.67 (
            IF %height% LSS 11.22 (
                identify -format "%%f:%%[size]:%%[fx:W/resolution.x]:%%[fx:H/resolution.y]\n" %1 >> %output%
            )
        )
    goto:eof

    :processB
        FOR /F %%x IN ('identify -format "%%[fx:W/resolution.x*0.393701]" %1') DO SET width=%%x
        FOR /F %%y IN ('identify -format "%%[fx:H/resolution.y*0.393701]" %1') DO SET height=%%y
        IF %width% LSS 8.67 (
            IF %height% LSS 11.22 (
                identify -format "%%f:%%[size]:%%[fx:W/resolution.x*0.393701]:%%[fx:H/resolution.y*0.393701]\n" %1 >> %output%
            )
        )
    goto:eof
