  Advances in Alpha-Blending
Konqueror Posted by Dre on Thursday 30/Nov/2000, @18:29
from the cooler-than-an-icebox dept.
Icon alpha-blending has taken some big steps forward today. First, Antonio Larrosa introduced alpha blending to the HEAD branch in CVS. Here's a screenshot showing one icon blended into another. A few hours later, Carsten Pfeiffer shot back with this tasty screenshot of Konqueror previewing text files with the mimetype icon blended in. Oh, I can't wait for 2.1 -- time to hit CVS! (screenshots below)

Thought I'd put the screenshots right inline for ya'll:

My word! That's absolutely gorgeous!

Off to hit the CVS, who's coming?

I see no need for this feature - except making KDE's code slower and bigger. Maybe not this one feature alone, but as we say in germany: "Kleinvieh macht auch Mist"

Blending disabled icons
by Maarten ter Huurne on Thursday 30/Nov/2000, @22:14
Will disabled icons be alpha-blended with the background to get a nicer semi-transparent effect? Currently, semi-transparency is implemented by displaying half the pixels, but displaying at half alpha would look much better. Take a look at the disabled icons in the toolbar of Konqueror in the screenshot.

Text file preview.
by JC on Thursday 30/Nov/2000, @22:44
The whole text-file thumbnail preview thing has a certain gee-whiz coolness to it, but I gotta say I think it is a step backwards from a UI standpoint. At first glance, all of the text files look alike - I can't distinguish between .txt, .cpp, .c , .h etc. The text included is completely useless unless I study each one close enough to identify the language (perl, C++, whatever). In the screenshot above, the original icons are still there, but now they are semi-transparent(looks very cool btw) and I can't really see them unless I look hard. I think I'll stick with my boring icons that give strong immediate cues about what the file types are.

Alpha blending in PNG images?
by Federico Cozzi on Friday 01/Dec/2000, @03:39
While the alpha blending for icons is very nice, do you plan to support the alpha channel of PNG images in Konqueror?
With KDE2.0, Konqueror uses only partially the alpha channel. I would like a complete support.

Thanks.

Actually i think these are exellent features because it makes the desktop attractive to windows users because when they see a console they panic but when they have an attractive GUI they feel like they're home.

Menus and toolbars
by Sam on Friday 01/Dec/2000, @06:30
Completely of topic, but:
Will Qt-3 or KDE-2.1 allow menubars and toolbars to be combined on the same bar to say. Today you can have more than one toolbar vertically connected....

Just like IE and Win2000 has it.

This is great. Unlike a lot of people I find many text utilities usefull and I'm not scared about the commandline but I do like a nice looking desktop and I like cool features even though they might not be terribly usefull. I think a lot of people would agree on that. I remember when I first booted up Linux (RedHat 4.2 I think) I though yuck this looks really amaturish. I didn't matter if you could to productive things with the thing. It didn't look proffesional and I think that has scared off a lot of people earlier. After looking at the Quick Time movies of Mac OS X I'm almost ready to waste a lot of money to get a Mac and play with that wonderful looking OS (yeah I know it's stupid but the OS just looks so good). I hope we will be able to make KDE look like Mac OS X some day. But before we can do that I think we got to get rid of X.

Why don't you folks just use GNOME and stop wasting your time?

I just rebuilt from CVS, but cannot see the new effect. Do I need to grad any new icons, and if so, from where?

Thanks,

Kind of on this subject
by Otter on Friday 01/Dec/2000, @11:29
Speaking of icons and alpha channels, I've been having a problem that no one else seems to have seen. Anyone know about this?

Using recent CVS, starting about three weeks ago, kicker icons look fine during the zooming. However, if I turn off the zooming, the icons are all greyed out. Going to the control panel for icon effects shows no effects active. If I apply an effect, it works but the icon is still greyed out.

This is after reinstalling from scratch with fresh CVS and a fresh .~/kde. Any ideas?

Antoñito es un maestro, el Malagueño más apañado que he visto. Además le tengo mucha envidia porque vive más cerca de mi niña (ella está en Sevilla y yo en Barcelona). Ya me gustaría a mi poder tener tus conocimientos para poder contribuir a KDE. Ahora que mi editorial ha cerrado mi revista podría meterme de lleno en ello, tendré que conformarme con la traducción.

I think this is great and a step forward. If you don't like it and you feel it slows you down, I am sure that there will be an option to turn it off. Keep up the good work guys!

I think this is a great feature, as long as i have the option to disable it. But what about font smothing and colored mouse cursors?

OK here is what i have to say in case u care:

this is one step towards a windows-like gui and when i say windows-like im mean a gui stuffed with crap nobody needs. stuff like this here is only slowing down the system - increasing kde-code - could make system unstable

when will we have a mouse-shadow ???

hi to everybody

to the developers and all who are interested ;)
by Spark on Sunday 03/Dec/2000, @15:07
maybe this is the right moment to discuss something, i lately noticed. i switched to icewm as my desktop of choice. this is not a big deal. i still like to use konqueror, kmail, knode, etc. these are great programs. but i noticed, that if i start any kde app, several kdeinit processes are started. i guess these are all the processes to provide enough of a kde environment, that those apps are able to run. i don't like this really much, but i can understand that it is necessary now. nevertheless, they should atleast quit, when they are not needed anymore. i hope that you will think more of other desktop environments soon. the power of choice is the power of unix. if you want to become a unix standard desktop, you shouldn't ignore the rules. this is not a rule, just a friendly reminder ;) i used to like kde a lot and it sure has a great potential when working together with other applications and not ignoring them.

Great stuff!!! But what about the overall GEOMETRY Control of KDE2 packages? It aint no good if it just looks good because it has to also function as a usable desktop too! Maybe you need some "Alpha Bent Feet Icons" and do a re-name to "Knome"?

Good stuff, but usefull?
by Christian Parpart on Sunday 03/Dec/2000, @16:26

Hi all,

this feature looks really very nice. But as you have read above, it's not really usefull.
Btw. the shadow cursor like the one from m$win looks nice too.

But I think the real missing features (for developers) aren't implemented yet.

So, what do you think about an integration of CVS access for the konqueror, such as TortoiseCVS for InternetExplorer it is. These is something required from all developers (developing for kde, gnome or all sourceforge projects) (otherwise an standalone K-CVS-app)

What do you think?

Text preview: Theoretically a very useful feature, but the way its done above is not good enough. First, as mentioned several times above, the icon is more important than the content and should thus be displayed stronger. Maybe in the top left corner going over the edge of the white paper, leaving a nice alpha-blended drop shadow on paper as well as background (with different displacements to show that the paper is closer to the icon...)? Alpha channel for icons: Cool, alpha channel should really be standard when dealing with any kind of graphics.

What would be even cooler is antialiased text. This might be a problem due to stone age X architecture - but if it could be done it would be soo great. It's getting sort of embarrasing not having antialiasing yet... Looks Win3.1-isch to MS users. .
