DESCRIPTION</B></FONT></P>
<BLOCKQUOTE>
<P><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">TPicShow is an
image slider control with 150 transitional effects in pure Delphi code. The
major characteristics of TPicShow are:</FONT></P>
<UL>
<LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">Image transition
can be controlled programmatically</FONT></LI>
<LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">Image can
be stretched or centered in the client area of the control</FONT></LI>
<LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">Control can
show a background image as centered, stretched, or tiled</FONT></LI>
<LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">Transition
process can use a separated thread</FONT></LI>
<LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">New transitional
effects can be easily implemented and added to the control<NOBR></NOBR></FONT></LI>
</UL>
<P><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2">TDBPicShow is
the data-aware version of TPicShow with ability to load bitmap, jpeg, and
metafile images (natively) from a blob field.</FONT></P>
<P><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><B><FONT SIZE="2">IMPORTANT
NOTE FOR DELPHI 3.0 USERS</FONT></B><FONT SIZE="2">: Two procedures in 'Graphics.pas'
are missing a call to 'BitmapCanvasList.UnlockList'. <BR>
This bug will cause VCL graphics functions, which have not been called from
the main thread, to hang. They cannot lock 'BitmapCanvasList' because the
main thread never unlocks it. Because of this bug, running PicShow in threaded
mode will lead your application to deadlock. For the bug's details and fix
please visit: <A HREF="http://www.dataweb.nl/~r.p.sterkenburg/generated/entry0016.htm">http://www.dataweb.nl/~r.p.sterkenburg/generated/entry0016.htm</A>.</FONT></FONT></P>
