Hi
The answer is very simple, a jpg is 32 bit (I believe) and is compressed.
Director has to decompress the image in order to display it. So while the
compressed file size is 32 k, the image info uncompressed is giving you the
1.2MB file size. Basically if you want to think of it somewhat
mathematically, determine the pixel width and pixel hieght of the image,
multiply them together then multiply that by 32 to get the number of bits
required to encode that image's data. Then divide the resulting number by
1024 to get its size in KBytes and divide that number again by 1024 to get
its size in MB. That is the actual uncompressed image size based on its
image data. When jpg compresses things, it does it by dropping out image
info that might not be readily distinguishable via the naked human eye, the
more you compress it however, the more info is lost and it begins to become
noticiably ugly. Does that help at all?
Sincerely
Mark
