| Hi, Quentin. The syntax you're using is correct; I use it with an
alpha of 0.5 for the disabled icons in Muonics applications. What
TkPNG version are you using (I'd recommend the latest from SourceForge
CVS). What Tk version (8.3+ is required for alpha support, I think).
Also, if you are also using the Img extension, it could be that Img is
loading your PNG instead of TkPNG, and I don't think Img supports the -
alpha trick in the format field.
