I suggest add support for images SVG.
Without CAD plug-ins that are very expensive.

XnView does not work native gamma correction in PNG.
The simplest formula is:
pow (channel/255, 1 / (gamma * 2.2));

gamma - gamma from PNG gAMA chunk
channel - RGB channel

Please - reply!

You must use JNG plugin...

It does not work PNG gamma correction

Does not work with JPEG image JNG alpha channel (chunk JDAA). In addition, if you remove the alpha channel (for JNG chunks with IDAT), the black pixels will remain in place a full alpha channel.

The plugin displays a JNG image with white background. Please fix it.

I propose to add support for JNG images (read / write). There must be full support for JNG.
