KSnapshot no longer capturing window decorations

Re: KSnapshot no longer capturing window decorations

That isn't the case here. The glow is captured using the Window Under Cursor option.

What graphics card and driver do you have?

Re: KSnapshot no longer capturing window decorations

I thought that you would ask. I did see that you (and the others) have an nVidia card/GPU. I have an Intel Corporation Core Processor Integrated Graphics Controller (rev 02) in my HP laptop. My Graphics details:

Graphics: Card: Intel Core Processor Integrated Graphics Controller
X.Org: 1.10.4 drivers: intel (unloaded: vesa,fbdev) Resolution: 1600x900@60.1hz
GLX Renderer: Mesa DRI Intel Ironlake Mobile GLX Version: 2.1 Mesa 7.11

Thanks.

I know correlation <> causation and all that, but since it worked before the nVidia blob upgrade and failed after, maybe I'll roll back the driver to verify. Too lazy to walk into the home office right now, though.

actually upon further investigation it dose capture the window decorations with the window-under-cursor setting.
like this.......



but not a background if opacity is enough to see it on screen .

I have a different, but similar issue:

With effects and window decorations turned on

This is with desktop effects turned off:


Any ideas?

[SteveRiley]

So it turns out that the symptom I reported earlier has absolutely nothing to do with drivers or window decorations. The Screenshot desktop effect controls whether the window glow is captured by KSnapshot. When that effect is off, KSnapshot excludes the glow. When that effect is on, KSnapshot includes the glow.

Now in your case, if I'm interpreting your images correctly, the upper one appears to have a glow, but KSnapshot appears not to recognize the glow's transparency, and instead renders the area formerly covered by the glow as solid black. What theme and widget style is that?

[sumski]

You are correct. Insted of the glow, ksnapshot produces solid black color.
That's bespin, but i have the problem also with oxygen.

[SteveRiley]

If you capture a screenshot of a window, save it as a PNG, then open it in Gwenview, do you see the hashmarks behind the transparent area? Example:

[sumski]

It's there. Any suggestion?

Here's the same thing but saved as jpeg:


Note that there's proper rendering of glow in ksnapshots preview, only the saved image doesn't show glow.

EDIT3:
Here's the result if i drag the image from ksnapshots preview directly to pastebin plasmoid:

Ah, this works as imgur saves the resulting image to png.

[SteveRiley]

Yeah, you have to use PNG. JPEG doesn't support transparency. I just tried the same thing I did before, but saved as JPEG -- and sure enough, the "transparent" bit is actually solid black.

[sumski]

Thanks for helping me clear this

[SteveRiley]

Well, I had no idea that dragging from KSnapshot was possible! That's cool. Now to figure out a way to drag-drop into Picasa...

[sumski]

There's a kipi-plugin for picasa export, don't know how/does it work.
Here it is:

My experience with the Kipi plugin's Picasa integration is that it works for a few weeks, then fails to log on. I've tried purging the Google token but that doens't always fix the problem.
