Re: Digger's hole lip

[Gervase Lam]

As the code cannot be compiled at the moment, I'm trying to sort out the 
Digger related things.

One of the Digger bugs listed on Savannah is that it is hard to do a Pingu 
reverse trick by making a Pingu Dig and then Bridge.  With a little bit of 
mathematical help, I've sorted this out by changing the shape in 
digger_radius.png.

(By the way, I've noticed splodges in the middle of the various cutters 
used in Pingus.  Is there any reason for this?)

With regards to darkening the edges of the hole, what I thought would be 
best would be to change digger_radius_gfx.png so that it had variable 
transparency using GIMP tools.  However, GIMP can only handle RBG images 
variable transparency, not the GIMP indexed 8 bit images that Pingus can 
handle.

So I asked about this in the GIMP newsgroup, and was told that a tool 
called pngquant would convert a PNG file to 8 bit, with the variable 
transparency being kept.  The tool for it is at the following site:

<http://www.libpng.org/pub/png/apps/pngquant.html>

However, whenever I try the new variable transparency PNG file, it just 
leaves a white trail behind.  Reading the ClanLib FAQ, it says that it can 
handle Alpha blending (i.e. Transparency).  Also, for some bizarre reason, 
it seems to make Bashers leave whole or bits of white behind as well.

Any ideas?

I've attached both the digger_radius.png that makes the reverse trick 
easier and the variable transparency digger_radius_gfx.png file.

Thanks,
Gervase.
