problem saving as png

I've been through this before, I usually just change the bg of the image to the one i'm using, but with #99cc00; as my body bg, I cannot for the life of me, save that same color.

I'm trying to figure out what you are talking about. I created an image and filled it with the color you specified, then saved it as a png. No problem. I opened it in Gimp to see if there is some problem with that color in png's and Gimp. Again, no problem. Can you describe exactly what you are doing and point to an example?

Create an html page with background-color of #9c0; then do the same with the image in GIMP, and save as PNG.

I'm seeing color variation.

I've tried that exact experiment just now, and see no variation. Perhaps you are doing something more that makes it a problem?

Are you sure this is not some setting in FF sinc you made that image a link?

When you open that image in Gimp and compare that with that webpage, does it in Gimp look like background or the foreground of the webpage?

The link doesn't have any effect on it. I added a link so I could show a border around it when hovered.

I'm using FF 2.0 on SUSE 10.1 and see no difference in the color between the image and the background.

You can have this effect with any HTML element. You don't need a link for that.

I see no problem at all on XP with FF2, Opera 9 or IE7, they all look fine on your page (i.e. same colour for image and backgoround). However, I remember I had a similar problem many years ago with a Macintosh. I think it was related to Gamma correction. Apples had (and probably still have) a different gamma setting, and this was creating a difference then (probably because my PNG did not contain the Gamma information then). Check that your PNG contains the Gamma information, and that your browsers can use it.

Best regards,

Olivier.

Thanks, but I've done it every which way from hell and back, and still looks off in FF/linux.

As he has repeatedly stated, the problem is under FF/Linux. There are many things in which FF/Win FF/Max and FF/Linux are different. It looks like FF/Linux isn't up to date with Gamma correction for some reason

Still, it seems to be specific to your setup. Mine, as I said in an earlier post, shows no color differences using FF 2.0 and SUSE 10.1.

FF1.5.0.9 running under FC5: no visible difference.

Actually - since the file and web page itself is OK, for some (... some people can see it correctly) then using simple logic, the problem isn't to do with The GIMP ...

If there is something wrong with the file then no one should be able to see it correctly ... unless the display process is correcting the problem ... ... doesn't sound likely ...

and thus it most likely IS a FF or Linux issue.

i.e. the people not seeing it correctly must have

either: a) a setting "issue" in FF or Linux (display)

or: b) using a version of FF or Linux (display driver) with that "issue"

...

I'm suspecting my X server or questionable nVidia driver or my new monitor is responsible...anyway, it seems not a gimp issue, but I figured I'd ask anyway.

Just to make sure I'm saving the image correctly, this is my process:

1 layer: with text 1 background (alpha channel removed): color: #99cc00; When I save as .png, I check the "save gamma", UNcheck "save background-color", and check the last item: "dither transparency from background".

Can someone please confirm that these are the correct steps moving forward with transparent PNG?

hhmm?? if you want the text, without the surrounding background to show up over the green bg of the page, why not just save it witha trasnaprent background? Just turn off the visibility of the background layer before saving.

When I save as .png, I check the "save gamma",

Actually, checking the " save gamma" optin is a good candidate for the color difference to show up at all!!! The problem is _all_ about gamma correction. You should e tried with9u tit already.

UNcheck "save
background-color",

NP. this doe snothing, but zero out tthe transparent area

and check the last item: "dither transparency from background".

Uncheck this - you don't want dithered transparency, you wnat true transparency!

Can someone please confirm that these are the correct steps moving forward with transparent PNG?

Actually - making a transparent background (as probably most realise) means that IE6 will probably pick a color to place there ... which is probably the original reason for the question ...

and just an FYI - my successful display test was: FC5=2.6.18-1.2257 + FF1.5.0.8 + nv=6600GT

This worked everywhere but IE6.

If i leave the bg color intact, it dithers inproperly in FF.
