XnView v2.49.3 but is also present in older versions

incorrect display of transparency.
In the attached archive samples.

also:
low speed open JPEG 2000 files when using the plugin openjp2.dll.
When using the LuraWave plugin.jp2 Dll (lwf_jp2.dll was in older versions ) the speed is 2-4 times higher and less CPU usage.

Plugin libwebp.dll incompatible with Windows xp. But there is a compatible version.

It is advisable to add the ability to view svg files, but only if using a small plugin, without third-party components. If of course this is possible.

all samples in the archive are not displayed correctly.
for example you can test on Firefox.
only XnView MP can load svg file
but you don't make a version of XnView MP for Windows xp.
Maybe you can make a plugin on the Firefox sources, they are free and there's a quality decoder.

these PNGs use alpha on 8bits data, currently not supported by XnView
