Imview: a portable image viewing and analysis application

Imview is a multi-platform image viewing and analysis application written by Hughes Talbot. The software has been developed for multi-platform operation, it runs under Linux, UNIX, Windows, and Mac OS/X.

The list of Imview features and capabilities includes:

• Support for many image formats.
• Ability to display 2D images and 3D slices.
• Support for TIFF stacks, animaged GIFs, and other multiple image formats.
• Display of 1-64 bit pixel data in integer and floating point formats.
• Inclusion of multi-spectral features.
• Display of 1D profiles of 2D images and 2D profiles of 3D images.
• Extraction of point statistics.
• Inclusion of support for false color colormaps.
• Manipulation of brightness, contrast, gamma, zoom, crop, rotation, and more.
• Support for image upload via sockets and shared memory.

Some Imview online documentation is available, but it is fairly out of date. The FAQ page is available for common questions, and the screenshots page shows Imview in action.

Imview has been written in C++ and uses FLTK, the Fast Light ToolKit for GUI features. LibTIFF, LibPNG, and ImageMagick are required for building the software.

Version 1.0.1 of Imview was recently released, a version 1.1.1 is currently under development. Imview is available under the GNU GPL, the code is available for download here. Source code and precompiled binaries are available.

We've been called all sorts of nasty names over the past few months, being accused of all kinds of malice and ill intent. I can assure you this is not the case. The reality is that if we're guilty of anything it's being a bit apathetic."

Berkeley DB XML: An Embedded XML Database (O'Reilly)

Paul Ford introduces Berkeley DB XML on O'Reilly. "Berkeley DB XML is an open source, embedded XML database created by Sleepycat Software. It's built on top of Berkeley DB, a "key-value" database which provides record storage and transaction management. Unlike relational databases, which store data in relational tables, Berkeley DB XML is designed to store arbitrary trees of XML data. These can then be matched and retrieved, either as complete documents or as fragments, via the XML query language XPath."

XSLT 2 and Delimited Lists (O'Reilly)

Bob DuCharme writes about delimited lists under XSLT 2.0 in his Transforming XML column. "The XSLT 2.0 specification is still a Working Draft, so you don't want to build production code around it, but it's still fun to try out some of the new features offered by the next generation of XSLT and XPath. In the next few columns, I'll look at some of these features. Most functions have been separated into their own specification, separate from the XPath 2.0 spec, because they're shared with XQuery: XQuery 1.0 and XPath 2.0 Functions and Operators."

Internationalizing the URI (O'Reilly)

Kendall Grant Clark covers the current state of XML URI specifications on O'Reilly. "As Paul Grosso said at the end of April, the progress of the XML 1.1 and Namespaces 1.1 recommendations may be slowed, if not stopped altogether, because of issues raised by the future of URIs. That is to say, because the future, in the form of IRIs, isn't here yet. The W3C's Technical Architecture Group has been unable to reach consensus on its Issue 27, which asks whether, when, and how to integrate IRIs into the core recommendations of the Web. One of the problems is that IRIs aren't finished yet, and it's notoriously tricky to rely on a formal concept or standard which, in some strict sense, doesn't yet exist. It's perfectly reasonable for the TAG and for other W3C Working Groups to point at the eventual IRI RFC and say, "do it like that". But until that RFC is finished, pointing blindly may cause more trouble than simply waiting till it is."

Thus the big question: if the strong-typing advantages of conventional compiled programming languages are moot, do we really need them? In 2020, will everyone be a Python programmer?"
