As i know, Png image is more smaller than jpeg. Is it right?

No not really. PNG is often bigger because it allows layering and transparency that JPGS dont. If you are concerned about image quality I would use the lossless quality properties that PNGS have (meaning that when re-sized the quality is not removed) however you can compress and work with smaller JPGS or GIFS but these do not provide the best quality. depends on your needs for the images.

All this stuff is intended to transfer the image that consist of remote user desktop capture. So as you understand , quality is mandatory requirement.

It depends on your situation. However, it seems like your best bet would be to use the JpgBitmapEncoder since you are encoding the image and transferring it across the network. I don't see where you will see an improvement in quality or size by using the PngBitmapEncoder.

Here is a good article on the differences between PNG and JPG that should help in your decision: http://www.turnkeylinux.org/blog/png-vs-jpg[^]
