HAVE_SSL_CTX_GET0_PARAM not defined when it should be.

the autodetected value HAVE_SSL_CTX_GET0_PARAM in osconfig.h should be defined when using openssl 1.1.1 since ssl.h does define SSL_CTX_get0_param. I think the call to CHECK_FUNCTIONWITHHEADER_EXISTS may be broken, either the function or the call parameters?

isnan issue on uclibc (e.g. alpine docker)

I tried to compile dcmtk on alpine but since it uses uclibc there's some issues. /dcmtk/config/tests/../math.cc:88:12: error: '::isnan' has not been declared return ::isnan(f); I tried it with various versions of gcc (6 and 5) but it looks like ublibc is the issue. May be use std::isnan or some othe...

improving DIMSE_createFilestream

I am running into a situation where in DIMSE_createFilestream, I need the creation of DcmOutputFileStream to be seperate from writing the metaheader. Specifically I want to use DcmOutputFileStream created from a FILE*. Now currently DcmOutputFileStream already supports that. But since DIMSE_createFi...

Re: Precompiled support libraries for DCMTK 3.6.1 and libico

Funny enough it was easy to solve under Windows and OS X. But under Linux... here's what I ran into. On Centos7. - http://rpm.pbone.net/index.php3/stat/4/idpl/27857191/dir/centos_other/com/libiconv-1.14-3.el7.x86_64.rpm.html on centos w/ no success. dcmtk can't find it, I am not sure what I should p...

Re: Open source jpeg2000 using reference codec (e.g. slow)

Oh, I want to mention that I also have a decoder based on jaspers, but no encoder. I based it on the RLE codec, so it's a much simpler, but older code, and every that I did wrong with, I fixed in the openjpeg version. It's useful for learning how to write an codec.

Open source jpeg2000 using reference codec (e.g. slow)

Just want to note that I have open sourced my jpeg2000 codec. I am releasing this mostly for the benefit of other open source software, not commercial. Some gotcha's about this implementation (I recommend offis's implementation for production) - Not well tested - Uses OpenJPEG, which is a reference ...

Re: open source crossplateform utility

I am also looking for some multi-frame mono2 images, mono1, and 16bit RGB to test a jpeg2000 codec based on openjpeg. I am still working on it, but I am pretty close.

open source cross-platform utility

Point of care, cross-platform software for importing DICOM CD and files then sending it to PACS.

Enjoy! Feedback is appreciated.

Curious. Is your US machine happen to be a Siemen's Acuson Sequoia 512? We have two sequoia, different models, and they both occasionally create bad RLE encoded images. Anyone tried just disabling RLE acceptance?
