Please check the KDE licensing page for correct texts.</pre>

I've changed my files now according to the KDE policy, but probably someone should also change the older files</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Needs to check image.isValid() before writing data via scanLine() pointers. The allocation may fail because of too large width*height.
Additionally, I would like the loader to return a Format_RGB32 image, when the data did not contain an alpha component.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">QImage has no isValid() method. Also I find no hint in QImage docu that it _can_ be invalid after this constructor.
Regarding alpha: the version of the WebP library I have installed on openSuse 12.1 (0.1.2) does not have
a function to check if the image has alpha data.
On the Google page https://developers.google.com/speed/webp/docs/api?hl=ru
I find the function WebPGetFeatures() but as said, my version does not have it.
