Project Description:
I need to have a java function built that will take 4 parameters.. A file name, a blob object, an X coord size (default to 100 px) and a Y coord size (again defaulting to 100 px). This function should return return a thumbnail image or a null if the file passed in does not allow a thumbnail image to be created.

The function needs to handle the following file types:

1) Jpg
2) Tiff
3) Gif
4) Png
5) PDF
6) DWG (Autocad style drawing files).

Sounds simple enough, I am JUST NOT a Java type developer.. I do more Oracle Pl/SQL development.. This function will be wrapped by a pl/sql function call and used in a small application I need for a school district I have offered to help with..

Thanks!
