A simple PNG (Portable Network Graphic) Image Viewer

Requirements

To use this program, you must have a 1.1 or higher version JVM.

Download the code

• PNGViewer.zip - a zip file.
• PNGViewer.tar - a tar file.

Using the program

To use the program, follow these steps:

1. Move the PNGViewer file into its destination directory.
2. Run it using this command line:
   java -classpath <classes.zip>:<PNGViewer> PNGViewer [image file]

   where:

   <classes.zip> is the full path to the java classes file distributed with your JVM
   <PNGViewer> is the full path to the PNGViewer file
   [image file] is an optional argument to tell the program an image to load at startup.

   Example (this is what I use on my solaris machine):

   java -classpath ~/bin/java/lib/classes.zip:~/Java/PNGViewer PNGViewer

   NOTE: Java is case-sensitive.

Notes

• The PNGViewer uses the PNGImageProducer by Jason Marshall (Thanks Jason!). The PNGImageProducer can be found off the PNG home page.
• For ease of use, I have bundled a copy of the PNGImageProducer and related files into the PNGViewer library. But, if you would like to use your own version of the PNGImageProducer, list it in your classpath before PNGViewer.
• The bundled PNGImageProducer only handles 8 bit per sample images. Jason intends to fix this, so keep a watch on his pages for updates.
