Identify .JPM-File | Missing "IM_MOD_RL_JPM_.dll"

[Mauleyy]

Hello community,
I have a problem with identify a .JPM file. A .JPM file is a JPEG-2000 Part 5 multipage file.
If I try to identify it I get the error:

Code: Select all

C:\Users\hueser>cd c:\tmp
C:\tmp>identify.exe DirectoryName = "C:\tmp\JPGATTREXC-2\JPGATTREXC-2\bin\Debug\testFiles\JPG2000\image.jpm"
identify.exe: unable to open image `DirectoryName': No such file or directory @error/blob.c/OpenBlob/2658.
identify.exe: no decode delegate for this image format `' @ error/constitute.c/ReadImage/501.
identify.exe: unable to open image `=': No such file or directory @ error/blob.c/OpenBlob/2658.
identify.exe: no decode delegate for this image format `' @ error/constitute.c/ReadImage/501.
identify.exe: unable to open module file `C:\Program Files (x86)\ImageMagick-6.8.9-Q16\modules\coders\IM_MOD_RL_JPM_.dll': No such file or directory @ warning/module.c/GetMagickModulePath/672.identify.exe: no decode delegate for this image format `JPM' @ error/constitute.c/ReadImage/501.
c:\tmp>

Here is the file I tried: https://dl.dropboxusercontent.com/u/702 ... /image.jpm

Can someone help me?

Greetings.

Can you remove the 'DirectoryName = ' part and try again?

Can you remove the 'DirectoryName = ' part and try again?

Didn't work :/ . And I don't know why there was the "DirectoryName = " at the beginning.
It don't works with the ImageMagick.NET and with the console.

Code: Select all

C:\Users\hueser>cd C:\tmp

C:\tmp>identify.exe "C:\tmp\JPGATTREXC-2\JPGATTREXC-2\bin\Debug\testFiles\JPG2000\image.jpm"
identify.exe: unable to open module file `C:\Program Files (x86)\ImageMagick-6.8.9-Q16\modules\coders\IM_MOD_RL_JPM_.dll': No such file or directory @ warning/module.c/GetMagickModulePath/672.
identify.exe: no decode delegate for this image format `JPM' @ error/constitute.c/ReadImage/501.

C:\tmp>

Does "identify -format" list the JPM format? It doesn't for me, so my version of IM (the standard pre-built Windows binary) can't read JPM files.

The format will be available in the next release (IM 6.8.9-8), you could do the following for now:

Code: Select all

convert j2k:c:\yourfolder\image.jpm image.png

or in Magick.NET:

Code: Select all

using (MagickImage image = new MagickImage("j2k:c:\yourfolder\image.jpm"))
{
  image.Write("image.png");
}

I tried the following code in .NET but it doesn't work as well.
The format isn't available

You are correct. I have updated the stackoverflow post and you should use the following code for now:

Code: Select all

MagickReadSettings settings = new MagickReadSettings()
{
  Format = MagickFormat.J2k
};

using (FileStream memStream = File.OpenRead(@"c:\yourfolder\image.jpm"))
{
  using (MagickImage image = new MagickImage(memStream, settings))
  {
    image.Write(@"image.png");
  }
}

Can you explain me how I can loop through the .JPM pages and get their width and height?

[dlemstra]

I send you a PM to ask if you could supply a .jpm file that contains multiple frames, your example does not contain multiple frames.
