Image Client for Palm OS

Image Client application for Palm OS employing Asta libraries. The client application provides the following functionality:

  • Establish connection with server application via secure login. See the example below.

  • Based on server setup, receive and present the list of Images available for viewing (Image names). Images can be static, such a collection of student photos stored on the server. Additionally, Images can be dynamic, such a collection of periodically camera generated (seconds, minutes, hours or other) jpeg images. The list of images presented in the palm os client application can be categorized based on image origin, e.g. Static photos of students and dynamic images generated by active security cameras, etc. See the example below.

  • Download then present the selected image in either gray scale or in 256 colors. The original image residing on the server may be of any size, e.g. 320x480 pixel. This entire image will be reduced in size in order to fit the palm screen while preserving the original aspect ratio of the image. A progress bar is available to display the image's download status.

  • Enable a software zoom-in capability. The user can use the touch pen to click and stretch (rubber band) a zone for enlarging. The enlargement is made from the original photo residing on the server. So, for example, assuming the original photo is 320x480 pixels in size the selected zoom in area is extracted from the original image then reformatted for the palm screen.
Zooming

  • Images can be database linked so that additional information (textural) can be presented along with the image. For example, a teacher may want to down load a student's photo along with all associated contact and/or medical information. Another example is a realtor may want to download the static photos of a home along with all associated information on the home.
