Lossless JPEG Image Compression

[Matthias_W_]

Dear Ladies and Gentlemen,

we are using IPP 6.x for lossy JPEG compression. As far as I know we had never updated from this version. Now we would like to use "Lossless JPEG Compression". But now it is gone :( 

Is it possible to get an older Version of the IPP where the image compression code still exists? Or is it possible to use the old UIC library on top of the IPP 9.x legacy libraries together with IPP 2017 (Update x)?!

Please help,

Matthias Wild

Please visit https://software.intel.com/en-us/articles/how-to-build-former-intel-ipp-samples-with-ipp-90-legacy-libraries to download the legacy libraries.

Hi Matthias,

There is also a KB article https://software.intel.com/en-us/articles/how-to-build-former-intel-ipp-samples-with-ipp-90-legacy-libraries on how to build UIC with legacy libraries. It describes on of possible ways of doing that.

Thank you very much so far for quick response. I tried to compile 

    build.cmd --sample=image-codecs --arch=ia32 --ws=vs2012 --ipp=static --conf=release clean build

But now I'm stucked with this error

    fatal error LNK1181: cannot open input file 'svml_dispmd.lib'

Yes, the "svml_dispmd.lib" is missing. Only a "svml_dispmt.lib" is provided by the "ipp90legacy_win" package.

Any suggestion how to proceed?

Sincerely,

Matthias Wild

Hi Matthias,

Try to update "BuildFunctions.cmake" from "builder" directory. Change svml_dispmd with svml_dispmt on line 94. Remove "CMakeCache.txt" file after that and do build command.

[Matthias_W_]

Okay, I did that already. I changed the input library directly in the Visual Studio project. Next missing lib is:

     LINK : fatal error LNK1104: cannot open file 'libmmd.lib'

Once I change this lib to (libmmt.lib) I ended up with two unresolved externals.

From "libmmt.lib" (libm_error.obj) :

    error LNK2019: unresolved external symbol __iob referenced in function _write_message

and something from the project itself (ippimage.obj)

    error LNK2019: unresolved external symbol _legacy90ippiResizeGetBufSize@44 referenced in function "public: int __thiscall   CIppImage::Resize(unsigned char *,int,struct IppiSize)const " (?Resize@CIppImage@@QBEHPAEHUIppiSize@@@Z)

What next? ;)

Hi Matthias,

Regarding last issue with "ippiResizeGetBufSize", simply comment this function call, because its result is never used.

Regarding the first, look here: https://software.intel.com/en-us/forums/intel-parallel-studio-beta-archived/topic/266345. There's something about __iob.

By the way, do you have other IPP installed (2017 or so)? You could take all missing libraries libmmd, svml_dispmd from there. Of course, they are not IPP's but belong to compiler. I don't know what you have.

Hello Sergey,

as far as I understand I have IPP 2017 installed. But I searched through the whole directory

    c:\Program Files (x86)\IntelSWTools

There are no files named "libmmd" or "svml_dispmd". Does it make sense?

BTW: I setup up "static" for IPP

    build.cmd --sample=image-codecs --arch=ia32 --ws=vs2012 --ipp=static --conf=release clean build

 but all projects are still set to "Multi-threaded DLL"

    /MDd or /MD

regrading the C/C++ Runtime. Is this the way it should be?

Hi Matthias,

What IPP 2017 package do you have? Is it a part of bigger package, like Intel Parallel Studio?

If yes, the required libraries are in "compiler\lib" directory. For example:
C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.2.187\windows\compiler\lib\ia32\libmmd.lib

If no, it can be a problem. I need to reproduce your building environment to advice anything.

[Matthias_W_]

Hello Sergey,

I have only two files in this folder:

     "libiomp5md.lib" and "libiompstubs5md.lib"

It seems to me that I have "IPP 2017 only" . No compiler, no additional packages.

Regards,

Matthias

And of cause the "IPP Legacy Libraries 9.0" :)
