This image is not a GIF, its a PICT in a resource in
/mozilla/xpinstall/wizard/mac/rsrc
then
mozilla.rsrc or netscape.rsrc depending on whether commercial or not.

Since its a PICT it doesn't support transparency (well Graphic Converter claims 
PICTS support alpha channels, but if you try to save one with an Alpha Channel it 
isn't transparent when you reload- besides, PICTs in resources and PICTS in files 
are two different things I think)

So to fix:

Figure how to use GIFs instead
Have multiple images, one for each background colour you want to blend width and 
fix the code.

Well, what do toolbar button icons in apps like 4.x and MS Office use, so that 
they can have a transparent background? Surely they don't use GIFs.

WIth icons, you can specify a mask (either 1-bit or 8-bit, depending on what type 

of icon). Where it's black, the icon is drawn; where it's white, nothing is 

drawn.



One solution I can think of is to make a mask for the PICT, and draw the picture 

manually.



I'm sure there is a better way, though.

Attachment: Image with correct alpha channel, but its a PNG :-(

Aparently, its a simple as this:

>In PhotoShop, you can let a new image have a transparent background. Then 
>just copy the non-white parts of your pict into that. Deselect, cmd-a, 
>cmd-c, and in ResEdit cmd-v.
>In your app call GetPicture() and DrawPicture().

But none of the s/w I have seems to understand PICTs with alpha channels. Perhaps 
someone with access to Photoshop can help?

Attachment: Image with correct alpha channel, as a PICT

Comment 12

[Andrew Thompson]

I filed a bug on it and the authour of Graphic Converter graciously sent me a 
beta with the alpha support for PICTs fixed - so I attached the image with the 
correct alpha channel.

Unfortunately it doesn't solve the problem... either somehow ResEdit is removing 
the alpha channel or the way the image is being displayed in the about box is 
ignoring alpha information.

What I've been hearing asking around the Mac programing community is that this 
can definately be done, but you need a user control... eg.

>Another possibility would be to make sure your image doesn't use white and

Obviously one will have to change the image so the white in the teeth and eyes is 
#FEFFE or something, to avoid these becoming transaparent too.

Recent versions of StuffIt Expander have an Aladdin logo with a transparent 
background in their progress window. Perhaps you could poke around in StuffIt's 
resources and see what they're doing?

Unsetting missed milestones to aid triage queries.

This is irrelevant since we will be checking in a version with an image well
shortly.
