Detailed Description
template<typename T>
class CVD::DiskBuffer2Frame< T >
A frame from a DiskBuffer2.
The frames in a DiskBuffer2 are image files loaded from disk.
- Parameters
-
T The pixel type of the frames to provide (usually CVD::Rgb<CVD::byte>orCVD::byte. If the image files are of a different type, they will be automatically converted (see Image loading and saving, and format conversion).
The documentation for this class was generated from the following file:
