Hi there,

I found a couple of jp2 images that cannot be opened in ImageMagick Display and cannot be converted with convert:

Code: Select all

C:\Temp>convert -version
Version: ImageMagick 6.8.5-7 2013-05-19 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2013 ImageMagick Studio LLC
Features: DPC OpenMP
Delegates: bzlib fontconfig freetype jng jp2 jpeg lcms lzma png ps tiff x xml zlib

C:\Temp>convert 01003557568_0060.jp2 01003557568_0060.png
error: cannot decode code stream
convert.exe: unable to decode image file `01003557568_0060.jp2' @ error/jp2.c/ReadJP2Image/404.
convert.exe: no images defined `01003557568_0060.png' @ error/convert.c/ConvertImageCommand/3106.

C:\Temp>convert 01003557568_0149.jp2 01003557568_0149.png
error: cannot decode code stream
convert.exe: unable to decode image file `01003557568_0149.jp2' @ error/jp2.c/ReadJP2Image/404.
convert.exe: no images defined `01003557568_0149.png' @ error/convert.c/ConvertImageCommand/3106.

Both samples are on archive.org, see
https://ia601707.us.archive.org/2/items ... 68_jp2.zip
Other pages in this archive are opened and converted with no problems.

Thanks for your work!

Works fine for me

convert 01003557568_0060.jp2 01003557568_0060.png

I am on Mac OSX Snow Leopard. The only difference I see is that my OpenMP is disabled.

What version of Jasper delegate library are you using. Mine is

jasper --version
1.900.1

The application is installed from ImageMagick-6.8.5-7-Q16-x86-dll.exe, as far as I remember...
Running on Windows 7 Pro SP1 64-bit.

Have no idea what the jasper delegate library can mean.
The jasper command is not available in my command line (unlike convert).

Read once again my previous post, found an inconsistence (I was running the x86 version on 64-bit Windows), reinstalled application using ImageMagick-6.8.5-7-Q16-x64-dll.exe - same (negative) result, still 'cannot decode code stream'...

IM uses the Jasper delegate library to process JP2000 images. See http://www.imagemagick.org/download/delegates/ and http://www.ece.uvic.ca/~frodo/jasper/ and http://en.wikipedia.org/wiki/JasPer

The fact that your convert -version shows jp2 means that it found the delegate library. That is all that I can tell you. Either there is a problem with the IM Windows binary or the jasper delegate library is too old or corrupt.

I am not a Windows user, so cannot help much further on this. Perhaps another Windows user can test for you.

Note also that Jasper cannot handle all the JP2 formats. But since I was able to convert it, that should not be the issue.

On Windows 7, the following ...

Code: Select all

convert 01003557568_0060.jp2 x.png
convert 01003557568_0149.jp2 y.png

... work for me with no problem.
