Does anyone know how to convert a .png image to a .gif images while still preserving the high quality and transparency. I've spent all evening trying to work this out, and I am having no luck.
Note: I am using PaintShopPro 8, not Photoshop.
:canadian:
GIF's don't have an alpha layer to allow transperancy...
why on earth would you want to us GIF anyway...
converting to a gif would cause you to lose quality. as GIF's are 8-bit palleted.. where as PNG's are 24+8bits
I use Photoshop to make godo gifs, and it allows to make some setting so it display right on some backgrounds. I'm not into painshop pro, but after searching at google I found this:
http://www.tiemdesign.com/HOWTO/2002/Novem...zer/default.htm
is a tutorial for exporting and enhancing gifs, similar to the "safe for web" of photoshop.
Good Luck
GIF is old school, the only drawback with PNG is that some browsers don't disply them correctly, like IE for example.
GIF cannot have partial transparency (Alpha). A Pixel is either a color, or transparent. Like what MageGuru said.
it really depends on the purpose, you cant use png's in a website because it wont display correctly on Internet Explorer, and since it is like the most used browser, then you should stick to gif if you want your website displayed correctly.
I dont understand why Internet Explorer still has this problem, they should give the ability to display png's.
GIF is not that bad, it might be old but not obsolete. It allows transparency and animation. The transparency is great if used correctly, not every transparency. Plus it is very small, it cna be compressed a lot, for example my sig is 2kb and it can be compressed more, im testing it at photoshop and I can compress it to 800bytes with no loss of quality, isnt that good?
hmm, IE can't display the alpha transparency of PNGs, that's right so far. but single color transparency is no problem. as it's not for Mozilla and opera. i prefer PNGs ober GIFs as they seem to be even little smaller (500B instead of 2k or so) and GIF needs some patent licence to display, I've read several times. for example, the GD library (used on some webservers) can't handle GIFs any more, but they added PNG support instead, aso.
OK, if you need animation, GIF is the only chance to do so, but as I see all those blinking smilies on the left here... I must say, I'm not that fan of animations surrounding you just everywhere.
BTW, I've seen some IE plugin saying to display alpha PNGs correctly... never found that again. anyone an idea about that?

oh, thanks for the info... i didn't know about that filter property.
you said the patent expired this year?
then read this:
UPDATED GIF INFORMATION, 06/17/03: Many have asked whether gd will support creating GIF files again after June 20th, 2003, when the well-known Unisys LZW patent expires. Although this patent exires in the US soon, this patent does not expire for another year in the rest of the world. Since I have no way of limiting distribution of GIF-creating code to US users only, I have opted to follow the same policy that the ImageMagick authors are following: GIF creation will not reappear in gd until the patent expires world-wide on July 7th, 2004. I realize this situation is frustrating for many; please direct your anger and complaints toward the questionable patent system that allows the patenting of such straightforward algorithms in the first place. Thank you!
found on the GD homepage (http://www.boutell.com/gd/)
and not everyone comes from the US...
(damn on this stupid quoting mechanism of this board....)
