export case as .zip

I think a very useful option would be the possibility to allow .zip as the output format in the "export images" dialog window. Actually JPG, BMP and DICOM are available.

Since RadiAnt can load zipped DICOM cases I find very handy to zip case and share them with other radiologists because of the reduced file size, moreover dealing with a single .zip file makes web or network transfer much faster than dealing with hundreds on unzipped .dcm files.

That's a handy feature that we will certainly add at some point.

7-Zip free libraries could be used to do this (and support .7z format as well)

just a few numbers about DICOM compression.

a case with a size of 201 MB (1566 DICOM files with jpeg lossless syntax) can be compressed up to 121 MB in .zip format and even 104 MB in .7z format

It will be highly appreciated if you add the ability of exporting and importing in .7z format.

May be also adding option to export DICOM images in lossless or lossy with JPG compression levels.

The 7zip library is available under a GPL license which makes it difficult for us to include it in the commercial software...

:-(

I'm not an expert of software licences...
anyway I know that WinRAR (which is a commercial software too), does support the .7z format (just the decompress mode).

maybe the .7z GPL licence allows to use the library just to decompress files even in commercial apps, but not to compress.

in our case, we could have compress/decompress support about .zip format and just decompress support for .7z format.

just another reminder.
at least the .zip support should not have license issues, isn't it?

There are no license issues with exporting to zip.
The only issue is free resources scarcity ;-)

I currently have 2 Radiant licenses for my home PC and laptop. And I frequently find my self transferring files from one to the other. This feature would save me lots of time and drive space... Any updates on this?

-tyvm Radiant team:-) Great great job!
