分享rave怎样支持jpg格式的字段？
含有jpg格式的数据需要输出到rave打印（系统需要穿过Internet，所以不可以用bmp格式），但好像rave的Bitmap只支持bmp格式。
rave的帮助中提到在TRvSystem的OnDecodeImage事件中用代码转换，但我发现这个事件好像根本不会触发。

需要加一个补丁，
问题16:打印JPEG
法一:在RAVE上增加JPEG控件
Bitmap components can only display bitmaps, not jpegs. You'll need the jpeg
add-on that's available from the Nevrona web site,
http://www.nevrona.com/rave/addons.shtml.
Installation instructions for TRaveJPEGImage
--------------------------------------------
1: Extract the files in this archive in your Rave main directory
(normally d:\RAVE5). Make sure to expand with directories so that the source
will be placed in it's own directory.
2: Copy the NDCsJPEG.PAS file into the appropriate directory for the version
of Delphi or C++Builder that you are using (for Delphi 6.0 it would normally
be d:\RAVE5\D6).
3: Start Rave, go to the preferences dialog (Edit|Preferences), select the
Packages tab and add the D:\RAVE5\ND_JPEG.BPL package file to the list of
installed package and click OK.
法二,程序中控制,具体参照//www.nevrona.com/rave/tips/rvtip31.html
