Free zooming software for linux

KmPlot 1.2.0 offers a software which has features of a mathematical function plotter for the KDE desktop. KmPlot is a mathematical function plotter for the KDE desktop. It has built in a powerful parser. You can plot different functions simultaneously and combine their function terms to build new functions.

The Unidentified Flying Raw (UFRaw) is a utility to read and manipulate raw images from digital cameras. It can be used on its own or as a Gimp plug-in. It reads raw images using Dave Coffins raw conversion utility - DCRaw.
UFRaw supports basic color management using Little CMS, allowing the user to apply color profiles. For Nikon users UFRaw has the advantage that it can read the cameras tone curves. Even if you dont own a Nikon, you can still apply a Nikon curve to your images.
My guiding concept in the development of UFRaw is to give all the essential (and some inessential) information and control over the raw conversion, with the hope that one could resolve all the exposure and white balance issues during the raw conversion.
The obvious advantage is that one can make full use of the raw data. The provisional advantage is that this way we circumvent the current 8-bit limit of the Gimp, as UFRaw does all manipulations in 16-bits.
Main features:
- Embed EXIF information - EXIF data from Nikon NEF, Canon CR2 and Pentax PEF files is embeded in the output JPEG image. This feature is in its preliminary development stages and the EXIF data is only partially created. For other file types the EXIF data is completely ignored, which is a pity. If you are interested in saving the EXIF information, you should check the ExifTool by Phil Harvey.
- Support full color management workflow.
- Zooming and croping.
UFRaw was originally based on Dave Coffins plug-in and Pawel Jochyms plug-in with live preview. Joseph Heled also offers a Gimp plug-in with some interesting features like zooming and saving EXIF information.
UFRaw is licensed under the GNU General Public License. This means that you can use it freely. If you decide to use it, the only thing that Im asking is that you will drop me a line telling me what you think of it. I might create a database of supported cameras in the future, so it would be useful if youll tell me what camera you are using and if you would be willing to test UFRaws support of your camera in the future. You can find my e-mail address at the end of this page.
Enhancements:
- This is a bug correction version.
- Non-integer shrink factors are now handled.
- A crash which occurred when the spot selector reached an image boundary was fixed.
- Some TIFF images are no longer wrongly identified as raw files.

GTKRawGallery software is an open source image viewer with camera raw files support written in Python and pygtk for Linux O.S.
Why should you try it? Because it has all you need from an image viewer: its very fast (tested with over than 10 Mb files) and light (less than 1900 code lines with a clean syntax for simple maintenance); finally, thanks to raw support, its the definitive solution to manage your photos!
Main features:
- Most known image formats supported;
- Camera raw files support (with DcRaw);
- 16 bit for channel color depth images recognized;
- Exif support (with exif.py);

- User friendly graphic interface compatible with several screen resolutions (minimum 800x600)

JGraph is a robust and complete graph component that is better than many of its commercial competitors. With the JGraph zoomable component, you can display objects and relations (networks) in any Swing UI.
JGraph can also be used on the server-side to read an GXL graph, apply a custom layout algorithm, and return the result as an SVG image.
With JGraph, users from highly-technical to very non-technical are able to display and edit complex information without the need to understand the underlying complexity.
JGraph can be integrated into custom applications and websites and allows to use and interact with any data model, from XML files to databases or other native systems.
Written in 100% pure Java, JGraph provides key features such as zooming, cell collapsing/expanding, undo, full event-handling, drag and drop support and much more.
Main features:
- Edge Editing: Add/Remove Points, Connect, Labels
- Moving/Sizing: Transaction-Based, with Live-Preview
- Selection: Single-Cell and Rubber-band Selection
- Zoom: Arbitrary Zoom, Uses Java2D
- Layering: View-Dependent Layering
- Grouping: Children Selectable; Uses Tree-Interface
- Grid: Customizable Size, Color, Appearance
- In-Place Editing: Direct Text Editing for all Cells
- View Attributes: Separate Attributes for each attached View
- Graph Layout: Easy Integration of Custom Algorithms
- Ports: Floating Connection Points for Vertices
- Graph Layout: Easy Integration of Custom Algorithms
- Handles: Flexible Interface for Cell-Modifications
- Drag and Drop: Between JGraphs and native apps
- Clipboard: Supports Multiple Transfer Formats
- Undo/Redo: Multi-View; for all available Operations
- Look-and-Feel: All Swing Pluggable Look-and-Feels
- Routing: Customizable with Default Algorithms
- Visibility: Hide edges, vertices and groups
- Attribute-Split: Per attribute control of view-only attributes
- Clustering: Collapsing/expanding of Groups
- Ant-Based: Ant-based build environment
- Precision: Double precision coordinates
- Labels: Draw Labels Along Edge
- Support: Commercial Support

- Attribute Maps: Custom behaviour, points and bounds
- Geometry: Standalone layout caches & cellviews
Enhancements:
- Snapping to grid for more than MAXCELLS now works correctly.
- Rounding from double to int has been removed in BasicGraphUI.RootHandle.mouseDragged.
- Edge label positions have been changed to be placed relative to the vertex perimeters rather than the centers of the vertices.
- A window close event has been added to the EditorGraph example.

ZOOM::IRSpy::Maintenance is a maintenance documentation for IRSpy.
The IRSpy application is implemented by five components:
- A library of classes within the ZOOM::IRSpy "namespace".
- A command-line invocation script called irspy
- A web-based UI - either this or the command-line script can be used to run the spy software, but the latter is more capable in that it also provides ways to interrogate the database of results.
- A small additional library, ZOOM::Pod, which is used by IRSpy and which is more conveniently included in this distribution than released and maintained separately.
- The configuration for a Zebra database that stores the harvested information.
These components are discussed in turn.

Links is graphics and text mode WWW browser, similar to Lynx. Links displays tables, frames, downloads on background, uses HTTP/1.1 keepalive connections, and features Javascript.
