How to display information about each page of a multipage tiff image using Identify

[ajb4930]

I upgraded from ImageMagick-6.8.6 to ImageMagick-6.9.0. Whenever I use identify to print information about a multipage tiff image, only information about the first page is displayed.

For example:

Code: Select all

identify.exe -format Depth-%p:%[depth]\nColors-%p:%k\nPageGeometry-%p:%g\nResolution-%p:%[xresolution]x%[yresolution]\nType-%p:%r\nCurrentPage:%p\nTotalPages:%n\n <<multipageFile.tif>>

Displays the following output:
Depth-0:1
Colors-0:2
PageGeometry-0:2550x3300+0+0
Resolution-0:300x300
Type-0:DirectClass Gray
CurrentPage:0
TotalPages:2

The command was displaying the above information for all pages of the file with the previous version of ImageMagick that I had installed; it is not working with 6.9.0. What do I need to do to get it to display the same information for the second (and remaining) pages?

Any insight would be appreciated. Thanks!

Try enclosing the arguments in double quotes

identify.exe -format "Depth-%p:%[depth]\nColors-%p:%k\nPageGeometry-%p:%g\nResolution-%p:%[xresolution]x%[yresolution]\nType-%p:%r\nCurrentPage:%p\nTotalPages:%n\n" <<multipageFile.tif>>

Does that help?

Try

identify multipageFile.tif

do you get multiple lines, one for each page. If not, then perhaps your tif is corrupted.

What about?

identify multipageFile.tif[0]
identify multipageFile.tif[1]
...
for each page you expect

Does it show info for each page?

What about

identify -verbose

does it show each page?

If you still have a problem, please upload your tiff file to some place such as dropbox.com and put the URL here, so others can verify.

Thank you for your feedback! I ran the command without

Code: Select all

TotalPages:%n\n

and I was able to get the correct information for each page of my multipage tif. My tif is not corrupted. I also tried displaying the format in a different order, but that didn't seem to work either.

I need to return information about each page with one command to be as efficient as possible. I wonder if this could possibly be a bug with version 6.9.0??

just leave off the page identifier, so rather than

identify multipageFile.tif[0]
identify multipageFile.tif[1]

Just use

identify multipageFile.tif

it will list each page/layer/frame.

The behaviour for "identify" changed between 6.8.0-0 and 6.8.9-0. The effect of the change is such that if the format string contains %n (the number of images), the rest of the format string is no longer repeated, once per image. I think this new behaviour is a bug.

This new behaviour applies to "identify" but not "convert -ping" (in 6.8.9-0 and 6.9.0-0). This still gives the old behaviour, issuing a format for each image, even when the format string contains "%n".

Examples:

Code: Select all

f:\web\im>c:\im\ImageMagick-6.9.0\identify   -ping   -format Depth-%p:%[depth]\nColors-%p:%k\nPageGeometry-%p:%g\nResolution-%p:%[xresolution]x%[yresolution]\nType-%p:%r\nCurrentPage-%p:%p\nTotalPages-%p:%n\n   x.tiff

Depth-0:8
Colors-0:256
PageGeometry-0:640x480+0+0
Resolution-0:0x0
Type-0:PseudoClass sRGB
CurrentPage-0:0
TotalPages-0:2

Code: Select all

f:\web\im>c:\im\ImageMagick-6.9.0\convert   -ping   x.tiff   -format Depth-%p:%[depth]\nColors-%p:%k\nPageGeometry-%p:%g\nResolution-%p:%[xresolution]x%[yresolution]\nType-%p:%r\nCurrentPage-%p:%p\nTotalPages-%p:%n\n   info:

Depth-0:8
Colors-0:221
PageGeometry-0:640x480+0+0
Resolution-0:0x0
Type-0:PseudoClass sRGB
CurrentPage-0:0
TotalPages-0:2
Depth-1:8
Colors-1:236
PageGeometry-1:480x640+0+0
Resolution-1:0x0
Type-1:PseudoClass sRGB
CurrentPage-1:1
TotalPages-1:2
