MP 0.39 Win: PNG displaying problem.

[Arty]

I have some PNG images which are displayed wrongly in XnViewMP (alpha channel is not applied) - here is a sample file.
It's 8-bit grayscale image with 8-bit alpha channel:

Code: Select all

D:\Test>pngcheck.exe SnowFlake01.png
OK: SnowFlake01.png (115x128, 16-bit grayscale+alpha, non-interlaced, 41.4%).

It's a know issue/limitation.

• PNG with transparency not showing
• PNG transparency problem
• 256-color png displayed in grayscale
• Incorrect display of a png image
• Alpha channel is ignored for grayscale PNG
• Wish: extract mask channel of PNG
• 8 bit png with alpha (8 bits) mask
• Partial Transparence in GFL_COLORS and GFL_GREY
