Crop images with irfanview

I'm using Irfanview that can be run through the command line. My problem is as follows:

My batch file:

i_view 32.exe /filelist=c:\test\*.pcx /crop=(1,2,3,4,5) /convert=c:\temp\*.pcx

Where 1 is x axis value, 2 is y axis value, 3 is width, 4 is height and 5 is origin.

I need to batch crop two hundred plus images, but my batch file crops all images to (1,2,3,4,5) specifications whereas i need the values to change depending on which image is being processed. In other words the first image that gets cropped is going to be 3×4 pixels cropped 1 pixel right and 2 pixels up from origin option 5, but I need the next file in the folder to have different values for all five variables of crop command preferably via a csv table or something. Does anyone know if this is possible?

Ps- irfanview has closed its forum to registering new accounts

@ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir"
SET "destdir=U:\destdir"
SET "filename1=%sourcedir%\q35953462.txt"
FOR /f "usebackqtokens=1-6delims=," %%a IN ("%filename1%") DO (
 ECHO(i_view32 %%a /crop=(%%b,%%c,%%d,%%e,%%f^) /convert=%destdir%\%%~na.pcx
)

GOTO :EOF

You would need to change the settings of sourcedir and destdir to suit your circumstances.

I used a file named q35953462.txt containing some dummy data for my testing.

file1.pcx,1,2,3,4,5
file2.pcx,5,4,3,2,1
file3.pcx,2,4,6,8,10

The proposed i_view32 commands are merely echoed to the screen. To activate following verification change echo(i_view32 to i_view32

With the file,

read each line and tokenise using , as a delimiter. There are 6 tokens, nominated as %%a and inplicitly %%b..%%f

I don't know the irfanview syntax for a single file, so I'll leave the polishing to you.

Note that ) needs to be escaped ^) because it is within a code block.
