Gif support true transparency?

gif support true transparency?

Tiff is a big image, so probably not. Do a web search for gif vs png. Might look at this also http://animation.about.com/b/2010/10/08/animated-gifs-vs-animated-pngs.htm

[Solved] True transparency possible in rxvt-unicode...?

I'm just wondering if it's even possible to run urxvt with true transparency, without adding command line arguments. I've tried urxvt*depth:32 and urxvt*bg:rgba:1000/1000/1000/cccc in .Xdefaults, and several permutations of scripts/hints found on the web, to no avail. urxvt -bg rgba:1000/1000/1000/cccc works as it should. Is there something obvious I'm missing, or is it just not an option?
Oops, if I had only read it before posting it... that should be urxvt*background, not urxvt*bg. Somewhere during my fiddling I changed that to match the command-line syntax just on the off chance. It didn't change anything when I first edited it, but apparently I've hit the magic config now. Never mind

Here's the relevant part:
urxvt*depth:32
urxvt*foreground:#B0B0B0
urxvt*background:rgba:2000/2000/2000/cccc
@ShortError: the transparent resource turns on pseudo transparency, not true transparency.

How to make a gif have a transparent background which is ready for use within premier pro cc ?

hi
guys
could you please explain the process of creating gif with a transparent background ?

Just create the document with transparency and save a gif (»Save As« or »Safe for Web« depending on your needs).
Are you talking about an animated gif?

Urxvt true transparency troubles (titlebar goes transparent too)

I'm running Openbox/GNOME under XGL/Xcompmgr with ATI's fglrx drivers. I'm trying to enable true transparency for urxvt, but for some reason when I set the transparency in ~/.Xdefaults the entire window (including titlebar) become transparent. Furthermore, the titlebar becomes nearly invisible even though the terminal window is almost opaque.
From what I've seen in screenshots, urxvt is supposed to make only the terminal portion of the window transparent. Has anyone encountered the same problem? Is there a workaround?
Xcompmgr flags:
xcompmgr -c -t-5 -l-5 -r4.2 -o.55
Pertinent ~/.Xdefaults settings:
urxvt*background: rgba:0000/0000/0000/eeee
urxvt*fading: 10
urxvt*shading: 30
urxvt*tintColor: grey
urxvt*depth: 32
urxvt*inheritPixmap: true
Thanks for any advice!

I've done a lot of searching, both in the Arch forums and out of them, and I can't really find anything related to this. I can find a bunch of posts about enabling transparency, but that's not the issue I'm having.
This issue might be due to the convergence of several issues among xcompmgr, urxvt, and awesome. If there is a thread lurking around somewhere that I missed, I can't find it.

Custom RepaintManager can't support true double-buffering?

RepaintManager doesn't provide a way to set bufferStrategyType. Custom RepaintManager can't support true double-buffering and 'gray rect' problem again?

Well looking at the source code, I was wrong... nevermind

Does anyone have TRUE transparency with urxvt in fluxbox?

Been using rxvt-unicode for a while and I really like it, and I loved how it looked in Openbox, the transparency worked wonderfully. But now that I've moved to Fluxbox, the transparency doesn't work at all. I've googled and searched a few forums, but everything I've tried fails. my Xdefaults are tweaked nicely, and I can certainly modify the appearance of urxvt, EXCEPT the transparency.
Is this a fluke of Fluxbox? Or am I just missing something?

rson451 wrote:iirc fluxbox has a transparency setting in it's own config, maybe the init file. it's been a while since i've used it but you may wanna start there.
Not quite what I'm looking for, but you're right.. With Fluxbox, you can make entire windows transparent. Which is fine, but I'm nitpicky. What I liked about Urxvt in Openbox, was that The terminal itself was transparent, while the window decoration stayed opaque. Thank you, though.
rine wrote:Don't you need compositing for true transparency? Maybe you missed something?
You most certainly do, and I should have mentioned that I'm running XCompMGR quite smoothly with drop shadows and all, I'm just having a small issue with one app.

GIF file with transparent background (white spots)

Hii. I've been having a problem. I was trying to make a signature earlier with gif on photoshop cs5. I tried making it with a transparent background and when I put it up on the forum, it gave me white spots. It's not noticeable with a white background as the spots are white, but with another color background, it would show. Can someone tell me why?
-- this is the image i made with a transparent background. and because it didn't work out, I decided to not use a transparent background and used a color of the background of the forum which was off gray. I know i have erased all of the white spots in the transparent file becuase it seems perfectly fine in the one with a gray background.
Can someone fill me in on as to what i am doing wrong?

Gif only supports 1 bit transparency: either on or off. The edges of your artwork are anti-aliased, and these cannot be converted neatly without setting the matte colour in the save for web dialog.
With Gif you have two option: either live with the coloured fringe surrounding your artwork (and it will only display correct when the background color matches the matte colour, or remove every single anti-aliased pixel, effectively creating a perfect sharp pixel edge.
Neither options are great: with the first option you always run the risk of ugly artifacts around the edges when the background color does not match, and with a perfect pixel edge it may look somewhat jaggy.
Solution: avoid Gif, and instead save as a fully transparent PNG. File size-wise not the greatest option, because Photoshop cannot optimize a PNG file properly. To do that, load up Color Quantizer, and open the PNG file. Then set the number of colours to about 256~512 (should be more than enough in your case), and save.
Done!
Get Color Quantizer here: http://x128.ho.ua/color-quantizer.html
If certain areas in your artwork look less than ideal, make use of quality mask/brush in CQ.

Copy/Paste Image from Clipboard - still no support for transparency?

I just tried to load an Image from the Clipboard by using DataFlavor.imageFlavor. Everything works well if the clipboard-image doesn´t use any transparency. When loading an image with alpha-channel (png or gif), the transparency occurs as black pixels. Here is the code snippet:
Clipboard clip = Toolkit.getDefaultToolkit().getSystemClipboard();;
Transferable t = clip.getContents(null);
BufferedImage img = (BufferedImage) t.getTransferData(DataFlavor.imageFlavor);img.getType allways returns TYPE_INT_RGB, even if the image contains alpha-data.
According to this Bug-Report
[http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4720930]
this should have bin fixed in 1.4.2, if i´m not wrong?
Can anyone confirm this problem, and is there any workaround? The one described in the bug-report doesn´t work for me, since clipboard-images in my case don´t match DataFlavor.javaFileListFlavor.

The best is to try it yourself I guess.
Go to Github and try pasting an image into the compose editor.
The editor definitely supports image pastings. They work directly in Chrome(ium).
Thus I am wondering why Firefox does not support direct pasting from clipboard into the editor.
See the attached screenshot regarding the editor I am talking about.

Animated Gif supported?

Mac OS 10.4.11 Acrobat CS4 - Can Acrobat support an animated gif.

Seem to be unsupported, sorry.
See this thread:
Re: I can't seem to get my GIF files on iBook. Anyone else having this problem?
Try a simple movie in a media widget or keynote slideshow widget instead.

I'm making an intentionally terrible montage. How can I convert a gif to a transparent .mov?

I want to be able to insert gifs into my final cut videos. They have to loop, and be transparent.
Is there a program that can convert them into transparent .movs or some other format recognized by Final Cut Pro?

Quick Time Pro should be able to open the GIF and save as a Quicktime .mov file. Whether the looping will work I don't know and can't test it.myself.
If you don't have QT Pro, it's a $30 license.

Where is my gif & tiff with transparency?

I saved a part of picture as both a gif & a tiff which was to include transparency. I wanted to see the difference in file size & quality. I went back to Organizer expecting to find the pictures but they aren't displayed. I tried importing the pictures but once I had selected them it says that it can't probably because they are already in my catalog. Well if they aren't in my catalog I can't see them. I can see them if I go to them using Windows Explorer. If they display in the Organizer where are they or do I have to change some setting?

Try searching the file through the Find menu. In case you want to just see the file info in organizer, you can make a new catalog, import the images and check the properties of the image.

Verizon Message+ gif support

I started using the Verizon Message+ app and really like it especially because of the integrated features for texting via a PC or a tablet. However I have tried to send and receive animated gifs and they do not work. They work with other apps including the default messaging app but not when sent or received in messages+. Is there a solution or does this app just not support gifs?

Randy_Randerson
I would like to look into this for you and see what is going on. Verizon Messages is a great application to use. Have you ever been able to send animation gifs? What happens exactly when you try to send these gifs via Verizon Messages?

Gif Support?

Does the starter edition not support gifs?
I can't find any mention of it in the documentation or in the comparison chart.

I ask because I have tried it. When I try to import a gif specificlly, I get a message saying "file type not supported" which I'm unable to find any documentation on.
This means I don't know if it's just that it dosn't support gifs,or if there's some other problem I'm having that I may well have with the full version as well.

Add animated GIF support in chats (for computer users)

Support!

I know that there's a post for getting GIFs availalble in the mobile section but I wanted to add it to the laptop/desktop section. I think that being able to add GIFs just like if they were regular images would be a tremendous improvement to the IM system.
