---------------
- Added retain/release mechanism to RImage by adding RRetainImage() and
RReleaseImage(). RDestroyImage() is an alias to RReleaseImage() now, but
will be removed in a future release because it no longer fits with the
semantics. Will be kept for a while to allow a smoother transition.
More about in wrlib/NEWS
For WINGs:
----------
- Small API change:
1. Renamed WMSetApplicationIconImage(), WMGetApplicationIconImage() and
WMSetWindowMiniwindowImage() to respectively WMSetApplicationIconPixmap(),
WMGetApplicationIconPixmap() and WMSetWindowMiniwindowPixmap()
They operate on a WMPixmap which is practically an X Pixmap with no alpha
channel information and the new name is more suggestive and also leaves
room for the new functions added for operating on images with alpha info.
2. Added WMSetApplicationIconImage() and WMGetApplicationIconImage() which
operate on an RImage and store alpha information too.
3. Added WMGetApplicationIconBlendedPixmap() which will take the image with
alpha set by WMSetApplicationIconImage() and will blend it with a color.
If color is NULL it will blend using the default panel color (#aeaaae)
All these changes will allow WINGs to handle images with alpha blending
correctly in panels and wherever else needed. More about in WINGs/NEWS.
- updated panels to use the newly available RImages if present and fallback
to old WMPixmaps if not, to properly show alpha blended images.
- replaced some still left malloc's with wmalloc's.
For Window Maker:
-----------------
- Fixed wrong mapping position of the "Docked Applications Panel" for some
icons.
- Smoother animation for the smiley =)
- Made images with alpha blending be shown correctly in the panels and the
icon chooser.
- The icon image set to be shown in panels ("Logo.WMPanel") will be
automatically updated if its entry in WMWindowAttributes changes (without
a need to restart as until now).
*** Note!!! ***
If you are developing applications with one of libwraster or libWINGs
then you should look to wrlib/NEWS and WINGs/NEWS to see what changed
and how should you update your code.

API change
|
|
----------
|
|
|
|
To allow a retain/release mechanism to be implemented for RImages, the
|
|
following new functions were introduced:
|
|
|
|
RImage* RRetainImage(RImage* image);
|
|
void RReleaseImage(RImage* image);
|
|
|
|
RDestroyImage() is now aliased to RReleaseImage(), but because it's no
|
|
longer compatible with the new semantics, it was only kept to allow a
|
|
smoother transition and the ability to run programs that were not updated
|
|
yet.
|
|
|
|
Do _NOT_ continue to use RDestroyImage(), because it will be removed in a
|
|
future version. You should start using RReleaseImage() in your code, and
|
|
also update all your existing programs to use RReleaseImage().
|
|
|
|
Also keep in mind that its name is also misleading: RDestroyImage() no
|
|
longer destroys images, unless they are not retained in some other place.
|
|
|
|
All existing code will continue to function with the new lib, even if not
|
|
recompiled, but you are encouraged to update your code to these changes
