Can I avoid decompressing stage?

ImageMagick will decompress ...

It's a pity.

Thank you for help.

My tiffs compressed with CCITTFAX4. Can I avoid decompressing stage?

Ok, but why those temp files so huge and numerous? My input files much smaller. It is strange that IM create one temp file with 60 Mb per one input file 10 Kb.

I also have tryed nconvert from here

It combine much faster and without using additional disk space

Those files should be deleted automatically. If they do not, then there is something wrong. You can delete them. See if they get left behind again. Yes, the files deleted automatically after combining if the number of files is small. But if number of files over 400, I get system warning about free ...

Ok.

But why in my %Temp% folder many files magick-6844AaBOq7CoiJCI apear with ~60 Mb during conversion folder with CCITTFAX4 (~10 Kb) tiff files ?

If I start to combine over 400 files, all free disk space (9 Gb) quickly disappears

Possible bug?

I use batch file where %1 is my filelist.txt

How can I modyfy my policy.xml?

Unfortunantly with newest version of IM I get an error

GeeMack, thank you.

Suppose I have file list filelelist.txt I need to create from those files a single multipage tiff.

How can I make it?

The number of pixels and dpi resolution is in the IM verbose

identify -verbose image

or can be extracted more directly from http://www.imagemagick.org/script/escape.php

You understand me correctly.
And again, you helped me. Thank you.

Thank you very mach.

How I can determine a only a page size of an image in pix and dpi?

fmw42 , thank you! It is work! Just noticed, in a command line it's works, but that does not work in batch file. The files are processed, but the output files are the same (only with changed date) @echo off title Trimmer setlocal set LIBRE=%BookShop%\DJVULIBRE\ set pagenumber=1 if exist %~dpn1 del ...
