Request: JNG transparency support

Post by Arty » Sat Sep 17, 2011 9:33 pm

Hi.
Could you please add transparency support for JNG format files? Currently latest XnView MP can view it but without transparency - it looks like alpha channel isn't applied to the image.

Thanks for cool program.

I can't attach JNG here, so I've uploaded it to another site. Here is a direct link - http://dl.dropbox.com/u/37559409/lattice.jng

You can use pngcheck utility to verify alpha channel presence in this file.
Here is output from it:

Code: Select all

D:\test>pngcheck.exe lattice.jng
OK: lattice.jng (526x490, 8-bit YCbCr + 8-bit alpha, 87.1%).
Here is a link to png2jng utility, so you can convert any PNG file to JNG by yourself.

JNG image from this page looks really bad:

XnView can't even open most images from JNGsuite.
