recording is started that has a frame rate other than the default.
- The include path to the freetype2 header files is now retrieved via a call to
'pkg-config --cflags freetype2' (suggested by Andreas Oberritter).
- The OSD now has full TrueColor support. There can be several "pixmaps" that can
be overlayed with alpha blending. All existing skins should work out of the box
with the TrueColor OSD - the only exception being cOsd::GetBitmap(). Since the
TrueColor OSD doesn't use bitmaps, this function will return a dummy bitmap, which
may not be what the plugin expects. As long as this bitmap is only used for setting
the palette, there is no problem. However, any other operations on this bitmap will
have no effect. See the description of the cPixmap functions in osd.h for details
about the new functionalities.
The "ST:TNG Panels" skin has been enhanced to automatically use the TrueColor OSD
if available.
The "osddemo" plugin has been extended to show some of the possibilities of the
TrueColor OSD if it is run on a system that actually provides TrueColor support.
Thanks to Reinhard Nissl for some valuable input, help with debugging, and an
implementation of the AlphaBlend() function.

@ -19,4 +19,11 @@ Demonstration of how a plugin can have its very own OSD setup.
It's a very primitive game that opens a small window in which the
user can draw lines with the Up, Down, Left and Right buttons.
The color buttons are used to switch color.
On a VDR system with TrueColor support it displays some of the
possibilities available with the TrueColor OSD. Once the "Animation"
pixmap is displayed, it can be moved around with the Up, Down, Left
and Right buttons. The Red button turns off the "Tiled Pixmaps"
display, and the Green button toggles the color display.
Press Ok to close the window.
