Convert multi-page tif to individual tifs

[bobnic]

I believe the following should work but all it produces is a copy of the original multi-page tif. I have used verbose just in case it helps. The final line of the verbose output would suggest that the resulting file would be the first image in scan0001.tif, but it really is a tif with all 5 images.

Code: Select all

convert -verbose scan0001.tif output%d.tif
scan0001.tif[0] TIFF 1286x1996 1286x1996+0+0 8-bit TrueColor sRGB 39.94MB 0.094u 0:00.097
scan0001.tif[1] TIFF 2046x1376 2046x1376+0+0 8-bit TrueColor sRGB 39.94MB 0.078u 0:00.090
scan0001.tif[2] TIFF 1806x2256 1806x2256+0+0 8-bit TrueColor sRGB 39.94MB 0.078u 0:00.082
scan0001.tif[3] TIFF 1287x2045 1287x2045+0+0 8-bit TrueColor sRGB 39.94MB 0.047u 0:00.059
scan0001.tif[4] TIFF 940x1302 940x1302+0+0 8-bit TrueColor sRGB 39.94MB 0.000u 0:00.017

The following does produce the expected individual bmp files.

Code: Select all

convert -verbose scan0001.tif output%d.bmp

Thanks for any pointers you can provide.

You are looking for the +adjoin option (http://www.imagemagick.org/script/comma ... php#adjoin). The following command will get you the requested result:

Code: Select all

convert -verbose scan0001.tif +adjoin output%d.tif

[bobnic]

That works.

Thanks for the very quick reply.

Just wondering if in fact I have stumbled upon a bug. Reading up on +adjoin:

In summary, ImageMagick tries to write all images to one file, but will save to multiple files, if any of the following conditions exist...

1. the output image's file format does not allow multi-image files,
2. the +adjoin option is given, or
3. a printf() integer format string (eg: "%d") is present in the output filename.

So shouldn't the fact that I included %d in the output file name meant that condition #3 should have "automagically" enabled +adjoin?

I just tried the command of your first post and I am getting separate files. I was not aware that using %d would also prevent the writer from writing a single file. Which version of ImageMagick are you using and what is your OS?

[bobnic]

ImageMagick 6.9.1--6 Q16 x64 on Windows 8.1

You need 2 percents in Windows:

• convert -verbose scan0001.tif output%%d.tif

You need 2 percents in Windows:

convert -verbose scan0001.tif output%%d.tif

That is true, when using BAT script files. From the command line, it is false. If typed at the command line, it would create a file named "output%d.tif".
