&amp;gt;&nbsp;&lt;br&nbsp;/&gt;<br>
&amp;gt;&nbsp;I&nbsp;think&nbsp;it&nbsp;has&nbsp;something&nbsp;to&nbsp;do&nbsp;with&nbsp;the&nbsp;Pixmap&nbsp;of&nbsp;the&nbsp;Gtk.Image,&nbsp;but&nbsp;I&lt;br&nbsp;/&gt;<br>
&amp;gt;&nbsp;can't&nbsp;find&nbsp;any&nbsp;examples.&nbsp;&nbsp;My&nbsp;image&nbsp;has&nbsp;a&nbsp;white&nbsp;color&nbsp;that&nbsp;represents&nbsp;the&lt;br&nbsp;/&gt;<br>
&amp;gt;&nbsp;transparency.&nbsp;&nbsp;Can&nbsp;anyone&nbsp;set&nbsp;me&nbsp;straight?&lt;br&nbsp;/&gt;<br>
&amp;gt;&nbsp;&lt;br&nbsp;/&gt;<br>
&lt;br&nbsp;/&gt;<br>
You&nbsp;can&nbsp;do&nbsp;this&nbsp;by&nbsp;specifying&nbsp;the&nbsp;transparent&nbsp;color&nbsp;of&nbsp;the&nbsp;pixbuf.&lt;br&nbsp;/&gt;<br>
&lt;br&nbsp;/&gt;<br>
You&nbsp;can&nbsp;use&nbsp;Pixbuf.AddAlpha&nbsp;().&nbsp;&nbsp;This&nbsp;will&nbsp;return&nbsp;a&nbsp;new&nbsp;pixbuf,&nbsp;as&nbsp;specified&lt;br&nbsp;/&gt;<br>
by&nbsp;the&nbsp;gdk&nbsp;docs&nbsp;here:&lt;br&nbsp;/&gt;<br>
http://www.pygtk.org/docs/pygtk/class-gdkpixbuf.html#method-gdkpixbuf--add-alpha&lt;br&nbsp;/&gt;<br>
&lt;br&nbsp;/&gt;<br>
I&nbsp;don't&nbsp;think&nbsp;you&nbsp;need&nbsp;to&nbsp;mess&nbsp;with&nbsp;the&nbsp;.Pixmap&nbsp;of&nbsp;the&nbsp;image,&nbsp;just&nbsp;create&nbsp;a&lt;br&nbsp;/&gt;<br>
new&nbsp;pixbuf&nbsp;from&nbsp;the&nbsp;file,&nbsp;add&nbsp;alpha,&nbsp;and&nbsp;assign&nbsp;the&nbsp;resulting&nbsp;pixbuf&nbsp;to&lt;br&nbsp;/&gt;<br>
imgCartIcon.Pixbuf.&lt;br&nbsp;/&gt;<br>
