"Convert to colors" and "Export" functions not working for PNG image with alpha channel

Post by dma_k »

Dear all,

I am trying to use "Export" function for attached PNG file (16×16 px, 32 bit colors) however the preview is showing not what I would expect:
export.png
In the same manner "Convert to colors" does not function correctly:
convert_to_colors.png
If I use "Remove alpha channel", then I get the same as in "Export" function preview.

XnView v2.40

right 'Export' must support alpha channel
