Using convert.exe on corrupt tif file

[lolhun1988]

Hi,

I tried to convert a tif file and I got this message during this process.

Code: Select all

convert.exe test_in.tif test_out.tif

Error:
Magick: unable to extend cache `test_in.tif': No space left on device @ error/cache.c/OpenPixelCache/4140.

Any idea why can not convert this file?
Version: ImageMagick-6.7.0-6-Q16-windows-static.exe

Regards,
Adam

what is the size of the input image and how much memory does your computer have? can you post a link to your input image so others can test. perhaps the input image is corrupt in some way?

is convert.exe the Imagemagick convert or the Windows convert? perhaps you are not using the IM convert, which many people rename to imconvert to avoid this confusion.

The input image size is 22 MB, my computer has 3 GB of RAM. Unfortunately I can't publish the image but yes the tif file is corrupt but I don't know that in what way! I tried to convert with the ImagMagick convert.exe because when I type convert to the cmd it says it is ImageMagick convert.

Code: Select all

C:\Documents and Settings\Moka>convert

what do you get from

identify -verbose test_in.tiff

what do you get from

identify -verbose test_in.tiff

This is the result:

Code: Select all

G:\Users\Durnek60>identify -verbose c:\Scan\Scan.tif
Image: c:\Scan\Scan.tif

Your image is 192 Mbytes.

There should also be more information from the -verbose info

Your computer may have limits on the amount of memory that can be used by any one application.

Irfanview gives this information about the picture so I think it's not 192 Mbytes it's impossible.

Sorry I meant Mega Pixels obtained by multiply width x height. Your image is binary (b/w), so that accounts for the smaller file size.
However, if IM converts that internally to truecolor? then the input file size would be 3x192 Mbytes and would require the equivalent on ouput. So you might be needing about 1.2 Gbytes. I am not sure how IM handles that internally!

however try

convert test_in.tif -type bilevel test_out.tif


or post a link to your file so others can test with it.

You could also try massive image processing commands, see http://www.imagemagick.org/Usage/files/#massive

Okay thanks for your help! I'm going to test it. Unfortunately I can't publish these pictures because those are secret. Thanks your help again. If I have problems or questions I'm going to write here.

I went to the press and made a corrupt tif file with the scanner here it is! So it occurs when we set a bad lenght parameter and I need to solve this problem.
