This document countains two "gif" images.
image 1 is a background image, image 2 is a partialy transparent image.
The showing on the screen is good, but printing don't show the visible part of 
the background.
The option of the mozilla browser is inneficient.
There is no problem with Internet Explorer or even with Netscape 4.7 (if you 
select the option "printing the backgrounds")

here is the code (very simple)

<html>
<head>
<title>Carte</title>
<meta http-equiv='Content-Type' content='text/html; charset=iso-8859-1'>
</head>
<body bgcolor=#FFFFFF topmargin=0 leftmargin=0 marginwidth=0 marginheight=0>
<div id='Layer1' style="position:absolute; z-index:1; left: 0px; top: 0px">
<img src="image1.gif" width=492 height=420></div>
<div id='Layer2' style="position:absolute; z-index:2; left: 0px; top: 0px">
<img src="image2.gif"></div>
</body>
</html>

First: always add the version of Mozilla that you are using. 
Second: this is not a blocker. Lowering to normal.

    
    

    
  


  
This is the test case with the images changed to the attached ones.

Maybe a dup of bug 141656 (hard to say without the correct Build ID), don't
know if bug 137637 comment 5 applies here.

really changing severity to normal.
Severity: blocker → normal

    
    

    
  
I would like people execute the test case and confirm this bug, it's very 
simple.
I work in cartographia domain and I think that the printing Mozilla problem I 
related, which is apparently similar to Bug 141656 and 137637 is fundamental 
for the credibility of Mozilla navigator.
What Netscape 4.7 was able to do, Mozilla 1.4 can't do !!!!
Somebody knows if new version (1.6)of Mozilla avaliable for good printing ?


    
    

    
  
I can report this buggy behaviour on:

Firebird, 20031207 Windows Official, Windows XP
Firebird, 20031203 OSX Official, Mac OSX 10.3.1
MSIE 6.0 (latest), Windows XP
MSIE 5.2, OSX

Firebird's build in print preview displays the correct image in all cases (as does IE's); however, Mac 
OSX's built-in print preview shows a buggy layout. So I doubt it's a printer driver problem. 

On the Windows machine, I see the buggy layout even when printing to Adobe PDFWriter 6.

The problem seems to be that, when printing, the transparent background on GIFs is rendered as 
white. There's a (possibly) clearer testcase at:
http://development.wendt.wisc.edu/map/testcase-gif.html

The problem presents with transparent PNG's as well:
http://development.wendt.wisc.edu/map/testcase-png.html

FWIW, the only browser I've seen this work with is Safari 1.1.1.

    
    

    
  
Also, in case it matters: the problem presents with gifs using either indexed or alpha transparency. 
Compositing looks perfect on screen, wrong when printed.

    
    

    
  
Confirmed with Mozilla 1.6
It works with IE6SP1
Status: UNCONFIRMED → NEW
Ever confirmed: true

    
    

    
  
I think that this bug is still present in FireFox 1.5 RC2! The following page has layered GIF images (which can be independently turned on and off). Attempting to print them from FireFox 1.0.7 and 1.5 RC2 doesn't produce the expected results (print preview, however, renders correctly).

http://www.poppyland.co.uk/norvillacts/norvillact03.htm

IE 6 prints them fine :-(
Opera 8.5 renders better than FireFox but offsets/scales the images in some strange way!

Any chance of someone taking a look at this - the bug has been open/NEW since 2003!

This problem is still not resolved (version 1.5.0.11).

Summary: stack a GIF on top of another image and the transparent areas in the topmost GIF will print as non-transparent, which is incorrect. Print Preview displays the GIF's transparent areas as transparent, which is correct.

I'd suggest this bug rates a higher severity. Transparent GIFs print properly in current versions of IE, Opera, and Safari.

    
    

    
  
This seems to be fixed as I couldn't reproduce this anymore in FF 3 and SM 2 builds of the last months.

This bug still occurs in the latest public version, 2.0.0.13. Please visit http://photos.friendsofedgewood.org/ and print it. You will see the map prints blank, at least it does when I direct it to my hp Laserjet 3200 and to Adobe PDF.

    
    

    
  
I can confirm that the bug appears to be fixed only in FF 3.x - FF 2.x still has the bug. As FF 3 should be out soon I don't consider this a problem.

    
    

    
  
No bug or patch referenced as the code fix.
