Transparent PNG image converted to JPG is messed up

[purch-FE]

Hello Guys
PNG Images with transparent background converted to jpeg are messed up.
Is it possible to flatten the image before converting it to jpeg please :
See http://stackoverflow.com/questions/2322750/replace-transparency-in-png-images-with-white-background
Basically doing the equivalent of
convert -flatten img1.png img1-white.png

If you know the dimensions of the PNG image, you can place it on a canvas that is the same height & width, which has a background color of #ffffff.

But ideally it would be nice to be able to flatten automatically onto a white background, without the need to use the canvas option.

How can we do that using a small light parametters ? using cw,ch and cc ?
I agree that would be nice if it could be done automatically and people can still override the color they would want.

Any help there, please ?

ngx_small_light can receive parameter such as cw,ch,cc for filling background color. But automatical flatten processing is not supported yet. (Patches welcome.)
