 Plat Viewer functions and buttons  (click to reveal-or-hide text):

general description

This application provides some elementary tools for viewing jpg images within a web browser.

It's intended to provide quick, simple access to the information recorded in Survey and Title Plats (which are stored as jpg files).

The application is coded in standard PHP, HTML, CSS and javascript. It doesn't use any ActiveX, applet or plug-in components.

By necessity, the application relies on internet technolgies that are antagonistic to efficient jpg handling.  Therefore: many plat images will display slowly;  and you could be subjected to some annoying "browser refresh" behaviors.  At times, you might have to "wait for the browser to catch up with you".

Plat jpg images range in size from 22 kb to 8,500 kb.  The average size is 1,500 kb. All plat images are large.  It might not be practical to view them if your computer has a slow internet connection or limited memory.

If your research requires more sophisticated (or faster) imaging tools, it is recommended that you save the jpg image to disk and use desk-top software (such as ACDSee, Irfanview, or others).

See "How to DOWNLOAD the document" (below) for further details.

pan

Use the "pan" tool to drag  "out of frame" document areas into the browser's view frame.
