I would like to create images in Javascript and display them on your 
browser. So far the best way of doing this _appears_ to be to dynamically
create an .XBM file within javascript and then ask the browser to display
it as an image.
1. XBM is monochrome. Firebird displays it as black with a transparent background
   I would much prefer to use white with a transparent background (ie using DIVs)
   Is there a way to tell mozilla to draw in a spacific color or is black
   hardcoded?

   I have been using .GIF uptil now but the complexity of compressing bitmaps
   is too much.

2. Better yet. Is there a way of passing an image directly to the browser?

3. Any news on when SVG will be supported

Reproducible: Always

Steps to Reproduce:
1. get an XBM image (eg those on your test suite)
2.
3.

Actual Results:  
picture is displayed in black

Expected Results:  
Request for information or new feature
Eg perhaps image should be displayed in forground colour?

This is about static XBM but there is a discussion of loading
dynamic XBM images under bug 202274

bug 202274 is totally unrelated

It's completely unclear to me what you think the Firefox bug is here.

I think its fair to say since writing this originally, I have learnt more
about XBM. 
Some of the documentation on XBM says it should be displayed in the current
foreground colour. However both mozilla and (as far as I can tell) microsoft
internt explore always display XBM in BLACK.
If this is truely the intended behaviour, then this is _not_ a bug.

I am now also using .PNG (see http://www.cs.ucl.ac.uk/staff/W.Langdon/pfeiffer.html)
which has the advantage of supporting colour but has the downside that pnglet
is CPU heavy. However as far as I can tell only you support it, Safari and
internet explorer do not let one load PNG's via a javascript: url.
If one could change the colour of XBM (as the standard says) it would still be
good to be able to do so.

Is there any way for the current foreground color to be passed to imglib?  This
could get really ugly for cursors and such.

I don't see a bug here. Request resolve invalid.

SVG support is on trunk and increasing steadily.
