Questions about RvMedia with XE7 (Save image to DbImage)

[rhernandezb]

Hi for all, thanks for read my question.....
I try save the snapshot in to Dbimage component and show error "[dcc32 Error] Unit1.pas(109): E2010 Incompatible types: 'TStream' and 'TRVImageWrapper'". I no know how solve this problem....I find in the forum but no appear info..... thanks for any information....

I try with this code


DbAdvPicture1.Picture.LoadFromStream(RVCamera1.GetCurrentImage);

[Sergey Tkachenko]

Code: Select all

var
  ImageWrapper: TRVImageWrapper;

ImageWrapper := RVCamera1.GetSnapShot;
DbAdvPicture1.Picture.Graphic := ImageWrapper.Bitmap.GetBitmap;
ImageWrapper.Free;

It was not mentioned in the help file, but GetSnapShot method works only if RVCamera1 is connected to a viewer or a sender, or OnGetImage event is assigned.
Otherwise, TRVCamera does not decode image frames.
