Hi Alexandre,

I would like to see it work for .MRXS as well on 64-bit WIN7

Thanks for doing a great job :)

Hi Alexandre,

This works (out of the box, like you said) with SVS files, but not with MRXS 1.9 files. I'm using Win7, 64-bit.

I think rather then an integrated and intuitive zoom function, a dropdown with the available planes within the selected file may be more useful (just like Axiovision does with the layer browser). I have  sample program myself that exports any layer from MRXS to TIFF (for minpulation in other software such as e.g. Photoshop). You and the list are welcome to it, but you should be aware that it's written in C#.

Today I wrote another app, but this time anyone can actually
run it without compiling. It's a Windows GUI app that uses
openslide library. It lets you choose a file supported by
openslide, and then it grabs the top level image from that
file, trims it to a maximum of 3000x3000 pixels and displays
resulting image as-is without scaling (there are scroll bars to

My next step is to implement zooming, and once that's done
that application can be used to quickly test further additions to
openslide library.

The zip archive is about 7 MB big, so I put it to my webserver:


No installation is needed, just unpack anywhere and run the
.exe file.

I've tested it in 64-bit Windows 7, but if you find any bugs,
please report them to me directly or using this mailing list.
