Description Ben Burton 2004-01-19 01:04:28 UTC

Version:           1.2.95 (using KDE KDE 3.1.4)
Installed from:    Debian testing/unstable Packages
OS:          Linux

(Received through the Debian BTS as #226116.)

(I cannot reproduce this bug since I only have i386 machines to test on, but if you CC 226116-submitter@bugs.debian.org then you'll keep the original bug submitter in the loop. - Ben.)

Karbon14 seems to be suffering an endianness bug on PPC.  When a blank document is selected, the page appears as cyan.  Drawing a square and filling it with solid white also produces cyan on the canvas, even though the color (and *all* colors) appears correct in the color dialog.  Seems like the karbon14-specific canvas code is messing up the rgb values due to endianness assumptions.

Any progress on this?  To provide a little more info...

When I select a circle, and set it's RGB value to black, that's fine.  When I then increase the R slider, nothing happens.  Increasing only the G slider makes it blue, while increasing only the B slider makes it green.

filling a shape with a colour at 99% opacity works fine.  100% opacity and <bang> it goes wrong as described above.

Comment 3 Paolo Peruzzi 2006-06-26 09:43:38 UTC

Same for me, I have to use the 99% opacity. If I choose 100% "white" for example, it is displayed as cyan eventhough any other viewer application shows the save file correctly.

I think this one can safely be closed now. Karbon in trunk does use Qt for all the drawing now, which does the right thing (TM) with regard to endianness.
