New JPEG2000 viewer for HiRISE images Options

[DataMiner]

Hi Folks,

The HiRISE team has been working on an improved image viewer/data explorer for our JPEG2000 imagery. We'd like to offer you all the chance to try out the release candidate before our public release next week, if you'd like to give it try. The new software is called HiView and can be downloaded from the HiRISE website.

For those of you that are interested: HiView is a platform native application (not java like the IAS Viewer), and as such it is a bit faster and more responsive. The performance using the jpip protocol is somewhat better than the IAS Viewer, and we are continuing to work on improving that. We are also continuing to develop the software. At this time, the software more or less matches the feature set of the IAS Viewer (panning/zooming and color/contrast stretching), but future versions will also include measurement tools and the like as well.

It should be noted that we will not be continuing to distribute the IAS viewer software after the end of this month, but we think HiView is a big enough improvement over the IAS Viewer that we hope nobody will be disappointed by that.

We'll be happy to hear any feedback that you can give us on this. The software is available for OSX, Linux, and Windows.

Enjoy!

Hi.

I've tried the Linux x64 version on Ubuntu 11.10 and works beautifully, with one exception: it doesn't load any path with a folder name that contains non ASCII characters. I.e. "~/imágenes", "~/облики", etc. The error description is "An image could not be obtained from the file."

Thanks for the report Fran. I've passed on the bug to our HiView developer. I believe the QT toolkit libraries HiView is built on top of all support unicode, so it's likely a problem in the hand off from the gui to the backend file loader, I think.

I have one question, and a couple of things that you might try as work-arounds

1) Were you loading the file from the file chooser (from the file->open dialog)?

2) If you were using the chooser, what happens if you drag and drop one of these files from a file manager? (Nautilus or konquerer)

3) What happens if you try loading the file via a terminal prompt? For example, change directories in a terminal window to the directory containing the file that you want to open, and then launch HiView with the file name as an argument. eg.( $ /path/to/HiView/HiView <your_file>)

Hopefully, one of these options will at least get it working for you right now, while we work on fixing the bug.

1. Yes.

2. Same error (with Nautilus).

3. From gnome-terminal (encoding set to UTF-8), no error, loads.

Thanks Fran,

That's useful information.
