Status: NEW

(SeaMonkey :: Page Info, defect)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9+)

When viewing the page info for a page that uses transparent images with white
text on them, these are show against a white background under Page Info/Media.
It might be better to use a different background, like the dark grey/light grey
checkerboard used by graphics applications.

Reproducible: Always
Steps to Reproduce:
Go to the given URL and show page info, all menu items will show as the same
white rectangle against a white background.

He did say dark grey/light grey, not light grey/white.

Timeless, could you review this?

Comment 7

[Aaron Kaluszka]

I fail to see how this helps transparent images with white text when the
background is still half white.  White text is more likely than grey text, and
the background should be made up of the lesser-used color.

Attachment: alternative checkerboard background image

Using a light/dark grey checkerboard would, in my opinion, work slightly
better. The attached image used the colors 0x808080 and 0xC0C0C0. I have also
decreased the size of individual blocks to 10x10 (instead of 15x15) as this
allows you to make quick judgements on the size of parts of the image.

hrm. this approach doesn't work well.

paint shop pro lets the user change the pattern colors and the grid size.

how about allowing the user to drag the image around?
being able to drag the image would allow the user to see a mask (which
indicates where transparency would be) as well as letting the user shift across
whatever background you provide.

the patch is trivial, you can have my review if you want it, but i wouldn't do
this it the way you're doing it :)

doesn't appear to be possible from js, however

MASS-CHANGE:
This bug report is registered in the SeaMonkey product, but has been without a comment since the inception of the SeaMonkey project. This means that it was logged against the old Mozilla suite and we cannot determine that it's still valid for the current SeaMonkey suite. Because of this, we are setting it to an UNCONFIRMED state.

If you can confirm that this report still applies to current SeaMonkey 2.x nightly builds, please set it back to the NEW state along with a comment on how you reproduced it on what Build ID, or if it's an enhancement request, why it's still worth implementing and in what way.
If you can confirm that the report doesn't apply to current SeaMonkey 2.x nightly builds, please set it to the appropriate RESOLVED state (WORKSFORME, INVALID, WONTFIX, or similar).
If no action happens within the next few months, we move this bug report to an EXPIRED state.

This still applies in my Forefox 3.0.11, and probably still applies in any version that uses a white background. An example image can be found at http://nedbatchelder.com/blog/200801/truly_transparent_text_with_pil.html
