Dame

Dame is a SIR file viewer. It's focused on comparing and interpreting two SIR files together. It is written in Python using the Qt toolkit, so it should be cross-platform, but has only been tested on Linux.

Dame is distributed under the MIT license.

Dependencies

• Python 2.7 or Python 3.3
• PyQt4 or PySide
• NumPy
• libsir

Features

Dame can:

• Load a SIR image (using the C SIR library)
• Display the pretty-printed SIR header
• Pan around the image by middle-click dragging
• Display information about the currently selected pixel
• Popup a magnified view of the selected region
• Use keyboard shortcuts to move crosshair (hjkl to move one pixel, use shift to move five pixels)
• Change image display range
• Store temporary notes in a dock widget
• Comparison view
  • Split view of two SIR files
  • For a given pixel, display the SIR values for both images simultaneously
  • Crossfade between the two SIR files (coming soon)

Installation

Arch Linux

dame is in the AUR, along with libsir, an important dependency.

Elsewhere

Ensure the standard dependencies are installed (Python, PyQt4, etc). The SIR C library requires a little more effort.

Download libsir from the MERS lab. It needs a few modifications to compile with a modern version of glibc. Also, the Makefile requires modifications to compile a shared library. Patches are available on the libsir AUR page, I recommend taking a look at the PKGBUILD and the patches to see how to compile and install libsir.

With libsir installed, dame should run just fine.
