Creating multipage Tiff from file list

[sergiokapone]

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 space, and thus, combining fail.

But what was your exact command line? If you do not reference your files correctly, perhaps bogus files will be created and left in your TEMP folder. Be sure you command is correct.

My command line same as you recomended.

Code: Select all

magick *.tiff newimage.tiff

Also I get an warnings during process

Code: Select all

magick: Unknown field with tag 292 (0x124) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/925.

I also have tryed nconvert from here

It combine much faster and without using additional disk space

Code: Select all

nconvert -o newfile.tiff -multi -out tiff -c 7  *.tiff

ImageMagick will read all the files into memory as those temp files. So if you do not have enough temp space, that could be an issue. But ImageMagick will use disk if not enough RAM. But that would account for your large use of temp space if you have many images to make into a tiff. Whether you use *.tiff or @filename.txt, this will happen with ImageMagick.

You can remove the warning, which is from an unknown tiff tag by adding -quiet right after convert.

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 am not sure, but they probably get enlarged when converting to ImageMagick internal format. Also your tiff files may be compressed and during the conversion, ImageMagick must decompress them.

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

[fmw42]

Can I avoid decompressing stage?

No, not that I know. ImageMagick will decompress and then recompress the output if desired by the -compress option.

ImageMagick will decompress ...

It's a pity.

Thank you for help.

Yes, IM de-compresses each input, and re-compresses the output.

IM is a general-purpose raster processing system. For some tasks, such as appending multiple tiffs into a single tiff, more specialist programs do the job faster and with less memory. For example, "tiffcp", available for Unix and Windows (via the Cygwin toolset).
