Re: [swfmill] Bitmap filter effects on buttons

[Ralf Fuest]

Hello,
there was an error in the parsing code for color filters, it should work
after the attached patch is applied. And your decision to send in the
file is right, because nobody can fix a bug that isn't known.

More technical stuff:
The end-condition for reading the ColorMatrix was wrong, so 21 instead
of 20 floats were read and that screwed up everything after the matrix.
I decided to add a size attribute to the list tag to make the source.xml
file look less confusing. size==19 for an list with 20 elements doesn't
look right ;). The Convolution filter also uses such a matrix and had a
similar end-condition, so i changed this attribute to an size attribute.
I couldn't check if this works because i don't have flash or an swf file
that contains this filter, but i think so.

Ralf

 Thanks!  I tried out 0.2.12.4 and it works for many of my buttons, but
 I found one which it doesn't like.  I've attached a sample swf and
 fla, and the output from the parsing.  The difference is that this
 button has an adjust color filter on it.  
 
 I can probably work around this, but I thought I'd send it along.
 Maybe it's another quick fix.
 
 Thanks again.

Hello Brian,
the current swfmill version doesn't support filters and blend modes for
buttons. I've written a patch to add support for this features.
Converting your sample swf to xml and back again worked.

When you want to compile it yourself you'll need an SVN version of the
source code, to get the codegen directory.
