input image file format

[seonjunn]

Hi!
Thanks for your great work.

I am wondering what happens if input image is jpg instead of bmp.
I could check with my eyes that this code still makes fine output.
But the weird thing was a file size.
Why does the file size increase with high quality level such as 95~100?
For example, when tested with 114kB jpg image and quality level 100, result was 295kB.
Is this because some of components in jpeg compression pipeline are missing in your work?

Kim
