@ -4008,3 +4008,7 @@ Video Disk Recorder Revision History
- Dropped the unused "stop recording on primary interface" stuff.
- Converting a grabbed image to JPEG is now done with the new function
RgbToJpeg() (see tools.h).
- The SVDRP command GRAB now determines the image type (JPEG or PNM) from the
extension (".jpg", ".jpeg" or ".pnm") of the given file name. The explicit
'jpeg' or 'pnm' parameter is still accepted for backward compatibility, but
has no meaning any more.
