RE: FLASH: screen captures

[Curtis Bay]

Hi DG,


This only applies to screen captures or other bitmaps with large areas

of flat color, not photos or images with lots of gradients and

dithering. I just ran a test on an 8-bit 1024x768 screen capture, once

with Lossless compression and once with JPEG compression at 100.


The original file size was 786k.

The JPEG compressed file was 272k.

The lossless compressed file was 17k.

I found this to be untrue in most cases. Setting photographic images to

"lossless" (reguardless of "smoothing") increases the file size

tremendously

95% of the time.

Even at 8bit they "look" better but are usually 3 times the file size

when

in swf format.
