.png test

Darkhorse · December 19, 2003 12:54PM

This kind of test is useless on the testing forum because you get no real feedback.
These are PNG files. They're different than GIF or JPG files in that the images have transparency that will make it blend into any background, dark or light and it has high image quality. It essentially has the image quality of a JPG and the transparent interlaced properties of a GIF but better... the only drawback is the size is greater, each of these images is 50kb.

On MY browser, Camino (which is unusual) the PNG's look fine but on your browser they may not appear correctly, if at all.

This test shows a PNG with a more blurry/transparent edge

same image, different background colour.

Both of the flipped versions of the royal pair have the same light blue background on my browser, and the edge is clear and distinct.

Darkhorse · December 19, 2003 2:21PM

hmm. how old is your computer? What browser are you using?

Me too.

About 2 years old, running IE 6.0 with XP Home 2002.

It's flipped for no reason whatsoever.
Perhaps I wasn't clear in my description. It's the same image in both posts but in subsequent posts the background colours in the message field are different because they alternate. I just was seeing how well the same image integrated on in both backgound colours particularly at the bottom parts of the portraits. Are you seeing the image of the heads within a box or something?

MacCrimmon · December 19, 2003 3:03PM

<< same image, different background colour. >>

I gotcha!

It may be how some people have their CU Forum "customize" settings configured which is causing them to not see the alternating post colours.

Both pngs look clean to me and I'm crawling with a Gen. 1 PIII/450 machine with Netscape 7.0, and IE 6.0

They look OK with the Mozilla browser running on Red Hat Linux 9.0.

So it's settled. PNG's will work well on this board in most browsers and with Linux, Windows and Macintoshes.

Thanks.

cosmicdebris · December 19, 2003 8:00PM

Transparency part is still not working ofr me. I still see the box and a color around the image other than the backgorund color here.

XP with IE 6 here.

cosmicdebris · December 19, 2003 8:10PM

Here it what I see with your PNG

Here is one I made ( P.S. You can not upload png files to the cu server )

Askari · December 20, 2003 12:46AM

They look really superb!

I'm running IE 6 on W98. The boxes do not blend out, nor does the one with a different background color show up as such; all have a moderately darker gray than the light bluish-gray of my text boxes (which I believe is CU's default). Cosmic's displayed version is much darker gray than what I see. The blurred edge does show as blurred along the bottom of their clothes in what appears to be an oval portraiture style.

Darkhorse · December 20, 2003 5:49AM

Odd that you wouldn't see the PNG's properly, Bill. Check your net settings.

Here's what I see. I use the 'sky blue' colour scheme.

See how the image interlaces into each background and can do this for any background.

canadiancoinguy · December 20, 2003 6:31AM

Same as Askari here.

trozau · December 20, 2003 6:56AM

I see a light sky blue background.

farthing · December 20, 2003 9:30AM

I see the same as Askari reports, a slightly darker background then CUs normal background color. That is except for your second post - the blurry/transparent picture background is totally transparent. IE 6 on a Windows 2000 platform

cosmicdebris · December 20, 2003 9:10PM

Phil I also see the same thing in PhotoShop 7.0 as I see here. The one I posted that shows a transparency is an 8 bit PNG. 24 bit PNGs show the dark grey background in PhotoShop and IE 6.0 for me???????

SYRACUSIAN · December 20, 2003 10:55PM

I see what Askari sees (PIII 450, IE 6, XP Pro). Phil, what exactly have you done with the reverse of the 1971 dollar and it looks orange (and transparent) ?

cosmicdebris · December 21, 2003 12:13AM

Well apparently there is some issue with IE 6. I just downloaded and Installed Netscape 7.1 and all Phil's images show up with full transparency.

spoon · December 21, 2003 12:21AM

They all look fine for me in Opera 6 on WinME. However, in IE6 they all have a light grey background.

The problem is that IE still does not fully support png.. here's a petition regarding this problem (I don't know how old it is).

cosmicdebris · December 21, 2003 12:23AM

The thing that's weird for me is I saw the same grey background in Photoshop for a 24 bit version????????

spoon · December 21, 2003 12:24AM

Here's a MS Knowledge Base article on the problem, with a dumb fix: PNG Files Do Not Show Transparency in Internet Explorer

EDIT = Here's a demo of the above fix applied.. seems to work, in IE but not Opera!

spoon · December 21, 2003 12:30AM

<< The thing that's weird for me is I saw the same grey background in Photoshop for a 24 bit version???????? >>

I got the same. That's the transparency layer, left visible in case you want to change the settings/color.. I think. I usually use bright green.

spoon · December 21, 2003 12:34AM

Ah! This might be a good fix:

If you save an image with a transparent background in Portable Network Graphics (PNG) format and then open the image inside Microsoft Internet Explorer or another Web browser, the image background may appear to be gray rather than transparent.

*****
This behavior can occur if you enable the True Color option when you save an image in PNG format in PhotoDraw 2000.

Internet Explorer versions 4.0 and later support transparent backgrounds in PNG images only if you save the image with a 256 color palette.

cosmicdebris · December 21, 2003 12:36AM

Test, Too bad the iamge size is so big.

cosmicdebris · December 21, 2003 12:43AM

I'll post an 8 bit example later but you will see a big difference between 8 and 24 bit images.

Got to go, time to see the final LOTR movie

spoon · December 21, 2003 12:58AM

<< Got to go, time to see the final LOTR movie

>>

it'll be another month at least before it gets here

Here's Goetz in png, made in Jasc PSP, reduced colors to 256, then saved with the existing palette and used single color transparency.. so it takes some of the fun out of it.. but works for me in IE:

...looks like a gif

Darkhorse · December 21, 2003 10:07AM

<< Test, Too bad the iamge size is so big.

>>

Looks a bit chopped at the end but otherwise it looks great. I think the png makes the coin look a bit more tangible. I think in the future when web space is cheaper and everyone's surfing on broadband you'll see a lot more PNG files on your screen.

Strange though, IE version 5 on the Mac will show the png transparency just fine.

Askari · December 21, 2003 10:12AM

Spoon's "gif" at least has working transparency for me.

cosmicdebris · December 21, 2003 7:09PM

The chopping is from the file size and the drop shadow. If I had added a few more pixels to the height that would have been fixed.

The MAC IE has a lot better PNG support than the Winblows version.
