EXIF Reader Library for C#

Digital cameras embed information in their images such as exposure information, camera settings, camera, lens, and manufacture information. I wrote this library to access this information with Microsoft's C# language. It currently supports over 35 tags. Programmers can use this library in their projects such as my Slide Show program below.

Example of use:
ExifReader r = new ExifReader("C:\\photos\\img_001.jpg");
Console.WriteLine("Exposure Time: " + r.GetExposureTime() + " Sec");

You can also run this as a stand alone Console Program like this:
ExifReader "C:\photos\img_001.jpg"

Language: C# (C Sharp)

GUI: None

Source code: ExifReader.cs

Executable: ExifReader.exe

Prerequisites: .Net Framework

Here is a sample output of a few of the tags:
Make: Canon
Model: Canon EOS 10D
White Balance: Auto
F19
Exposure Time: 1/1000 Sec
Exposure Program: Shutter Priority
ISO: 400
Exposure Bias Value: -0.5
FocalLength: 85
Flash: No Flash
EXIF Version: 2.20

Slide Show, C# Edition

I wrote this program for my photo club. We needed a simple way to display our images full screen at our meetings. The program launches a File Chooser . After you select the first image to display it goes to full screen mode with a black background and no border. Use arrow keys, Page Down/Up, or Home, End to navigate. Delete will move it to a folder called _Delete, C will copy to _Copy, R will rotate right, L will rotate left, the space bar will display detailed EXIF info, and Esc will exit the program. You can toggle on/off the EXIF footer info with F1, and toggle on/off the Auto-Rotate feature with F2. Because this is written in C# you need the .Net (Dot Net) Framework. This program is also a great way to select your best images like you would on a light table because it can display images faster than PhotoShop and you can quickly move images to the Delete Folder.

Language: C# (C Sharp)

GUI: Windows Forms

Source code: Form1.cs and ExifReader.cs or zip file.

Executable: Slideshow_04.exe

Prerequisites: .Net Framework

Slide Show, Java Edition

I originally created my Slide Show program in Java but was not happy with it's performance on large images so I stopped development. To run this on Windows or Mac save the jar file to your desktop and just double click on it. For linux use java -jar SlideShow.jar. You need Java 1.4 or above.

Language: Java 2

GUI: Swing

Java executable jar file with source code: SlideShow.jar

Prerequisites: Java JRE 1.4

GIS Shapefile Viewer

This is a simple GIS Shapefile Viewer I created using the Open Source Geotools library. It can view GIS data in the popular ArcView format. You can view multiple layers at once. Shapefile data can be viewed from your hard drive or from a URL. It offers a zoom and pan toolbar. It's a great way to view GIS data on any Java enabled device. Because I use Java 1.1 it works well with PDAs such as the IPAQ or Zaurus. It will also run on Linux and Mac OS X and it's free. GeoTools is a powerful library which can do much more so you can add on to this viewer if you wish.

Language: JDK 1.1 and Personal Java.

GUI: AWT (Abstact Widowing Toolkit)

Source Code: GISViewer.java

Download the complete package with GeoTools library: GISViewer.zip

Download sample data

This is a similar viewer I created with ESRI's Map Objects for Java, a powerful library for creating GIS GUIs. ESRI has a 60 day demo you can order if you wish to try this out. Simply add their Jar file to your CLASSPATH and run this viewer with java GISViewerESRI <shapefile1> <shapefile2> ...etc. This viewer is so intuitive and easy to use it's a great way to display a custom map on a live CD. I could easily customize it for special projects.

Language: Java 2

GUI: Swing

Source Code: GISViewerESRI.java and GISViewerPane.java

Download the complete package : GISViewerESRI.zip

Prerequisites: Java JRE 1.4

Neil's JPEG Browser II

Language: Java 2

GUI toolkit: Swing

Source Code: unzip the jar file.

Download executable jar file: JpegBrowser2.jar

Prerequisites: Java JRE 1.4

(Double click on the jar file to execute, or right click and open with javaw, or use at command line: java -jar JpegBrowser2.jar)

I did a complete rewrite of my JPEG Browser in 2003. This one uses a Windows Explorer like file tree structure I invented for navigation. It also displays the EXIF Metadata produced by digital cameras. It currently only supports viewing JPEG GIF, AND PNG images. Folders are displayed first followed by filenames in the tree. Use up and down arrows or the mouse to navigate. The dropdown menu is to select the drive. My webstart version was too slow for some reason so I only produced an executable jar file. This program requires Java 1.4 or greater.

Neil's RPN Calculator

This Scientific calculator uses RPN Logic (Reverse Polish Notation) similar to the HP Engineering Calculator I used in college. For example: To add 2 and 3 use "2 Enter 3 +." Everytime you press Enter it adds the number to the stack. It's designed for the Zaurus PDA but runs just fine with the Standard Edition (J2SE) so you can run it on your PC as well. It could also be repackaged for the IPAQ with the Jeode JVM installed. To launch this calculator look for the RPN icon in the Jeode Folder.

Language: Personal Java (Same as JDK 1.1)

GUI: AWT (Abstact Widowing Toolkit)

Source Code: Rpn6.java

Zaurus IPK package: RPN_Calculator_0_6.ipk

Language: PHP, Java Servlet, or JSP

GUI: Browser based

Source Code:
  PHP Version: Spreadsheet.php
  Java Servlet Version: Spreadsheet.java
  JSP Version: Spreadsheet.jsp

Example: Test Drive the PHP version here!
