virtual int InitImage(BIAS::ImageBase &Image)
Defines a common interface to different devices.
This class implements a video streaming client using shared memory to receive images from another app...
unsigned int GetWidth() const
Definition: ImageBase.hh:312
virtual int OpenDevice()
selects the first available device to open (e.g.
unsigned int GetChannelCount() const
returns the number of Color channels, e.g.

void SetDebugLevel(const long int lv)
Definition: Debug.hh:318
unsigned int GetHeight() const
Definition: ImageBase.hh:319
virtual int PreGrab()
Do last preparations before grabbing (e.g. start ISO transfer)
static int Save(const std::string &filename, const ImageBase &img, const enum TFileFormat FileFormat=FF_auto, const bool sync=BIAS_DEFAULT_SYNC, const int c_jpeg_quality=BIAS_DEFAULT_IMAGE_QUALITY, const bool forceNewID=BIAS_DEFAULT_FORCENEWID, const bool &writeMetaData=true)
Export image as file using extrnal libs.

virtual int GrabSingle(BIAS::Camera< unsigned char > &image)
virtual int PostGrab()
Stop anything started in PreGrab()
