Allocation/Deallocation

A MovieSaver can be created with the usual tools:

Functionality

A MovieSaver object simply opens a movie file and writes multiple frames into that file:

// This example saves multiple bitmaps into a movie file.
if (movieSaver == nullptr)
return maxon::OutOfMemoryError(MAXON_SOURCE_LOCATION);
// open the movie file
const IMAGERESULT res = movieSaver->Open(saveMovieFile,
typicalFrame, 25, FILTER_AVI, nullptr, SAVEBIT::NONE);
return maxon::IoError(MAXON_SOURCE_LOCATION, MaxonConvert(saveMovieFile, MAXONCONVERTMODE::NONE), "Could not create movie file."_s);
// store each frame
for (Int32 frame = 0; frame < frameCnt; ++frame)
{
// get bitmap content
// this is a just a custom function
GetBitmapOfFrame(bitmap, frame) iferr_return;
// store bitmap data
if (movieSaver->Write(bitmap) != IMAGERESULT::OK)
return maxon::UnknownError(MAXON_SOURCE_LOCATION);
}
movieSaver->Close();
