Detailed Description

Camera API

Member Function Documentation

◆ AddTag()

virtual void MM::Camera::AddTag ( const char *  key,
const char *  deviceLabel,
const char *  value 
)
pure virtual

Adds new tag or modifies the value of an existing one These will automatically be added to images inserted into the circular buffer. Use this mechanism for tags that do not change often. For metadata that change often, create an instance of metadata yourself and add to one of the versions of the InsertImage function

Implemented in CCameraBase< U >.

◆ ClearROI()

virtual int MM::Camera::ClearROI ( )
pure virtual

Resets the Region of Interest to full frame.

◆ GetBinning()

virtual int MM::Camera::GetBinning ( ) const
pure virtual

Returns the current binning factor.

Referenced by CCameraBase< U >::GetPixelSizeUm().

◆ GetBitDepth()

virtual unsigned MM::Camera::GetBitDepth ( ) const
pure virtual

Returns the bit depth (dynamic range) of the pixel. This does not affect the buffer size, it just gives the client application a guideline on how to interpret pixel values. Required by the MM::Camera API.

◆ GetChannelName()

virtual int MM::Camera::GetChannelName ( unsigned  channel,
char *  name 
)
pure virtual

Returns the name for each Channel. An implementation of this function is provided in DeviceBase.h. It will return an empty string

Implemented in CCameraBase< U >.

◆ GetComponentName()

virtual int MM::Camera::GetComponentName ( unsigned  component,
char *  name 
)
pure virtual

Returns the name for each component

Implemented in CCameraBase< U >.

◆ GetExposure()

virtual double MM::Camera::GetExposure ( ) const
pure virtual

Returns the current exposure setting in milliseconds.

◆ GetImageBuffer() [1/2]

virtual const unsigned char * MM::Camera::GetImageBuffer ( )
pure virtual

Returns pixel data. Required by the MM::Camera API. GetImageBuffer will be called shortly after SnapImage returns. Use it to wait for camera read-out and transfer of data into memory Return a pointer to a buffer containing the image data The calling program will assume the size of the buffer based on the values obtained from GetImageBufferSize(), which in turn should be consistent with values returned by GetImageWidth(), GetImageHeight(), GetImageBytesPerPixel(), and getNumberOfComponents(). The calling program also assumes that camera never changes the size of the pixel buffer on its own. In other words, the buffer can change only if appropriate properties are set (such as binning, pixel type, etc.) Multi-Channel cameras should return the content of the first channel in this call.

Supported data types are byte (8 bits per pixel, 1 component), short (16 bits per pixel, 1 component), float (32 bits per pixel, 1 component, not supported by the UI yet), RGB_32 (8 bits per component, 4 components), RGB_64 (16 bits per component, 4 components, not supported by UI yet).
RGB buffers are expected to be in big endian ARGB format (ARGB8888), which means that on little endian format (currently most/all? code is compiled for little endian architecture), the format is BGRA888 (see: https://en.wikipedia.org/wiki/RGBA_color_model).

Implemented in CCameraBase< U >.

◆ GetImageBuffer() [2/2]

virtual const unsigned char * MM::Camera::GetImageBuffer ( unsigned  channelNr)
pure virtual

Returns pixel data for cameras with multiple channels. See description for GetImageBuffer() for details. Use this overloaded version for cameras with multiple channels When calling this function for a single channel camera, this function should return the content of the imagebuffer as returned by the function GetImageBuffer(). This behavior is implemented in the DeviceBase. When GetImageBuffer() is called for a multi-channel camera, the camera adapter should return the ImageBuffer for the first channel

Parameters
channelNrNumber of the channel for which the image data are requested.

Implemented in CCameraBase< U >.

◆ GetImageBufferAsRGB32()

virtual const unsigned int * MM::Camera::GetImageBufferAsRGB32 ( )
pure virtual

Returns pixel data with interleaved RGB pixels in 32 bpp format

Implemented in CCameraBase< U >.

◆ GetImageBufferSize()

virtual long MM::Camera::GetImageBufferSize ( ) const
pure virtual

Returns the size in bytes of the image buffer. Required by the MM::Camera API. For multi-channel cameras, return the size of a single channel

◆ GetImageBytesPerPixel()

virtual unsigned MM::Camera::GetImageBytesPerPixel ( ) const
pure virtual

Returns image buffer pixel depth in bytes. Required by the MM::Camera API.

Implemented in CCameraBase< U >.

◆ GetImageHeight()

virtual unsigned MM::Camera::GetImageHeight ( ) const
pure virtual

Returns image buffer Y-size in pixels. Required by the MM::Camera API.

Implemented in CCameraBase< U >.

◆ GetImageWidth()

virtual unsigned MM::Camera::GetImageWidth ( ) const
pure virtual

Returns image buffer X-size in pixels. Required by the MM::Camera API.

Implemented in CCameraBase< U >.

◆ GetNumberOfChannels()

virtual int unsigned MM::Camera::GetNumberOfChannels ( ) const
pure virtual

Returns the number of simultaneous channels that camera is capable of. This should be used by devices capable of generating multiple channels of imagedata simultaneously. Note: this should not be used by color cameras (use getNumberOfComponents instead).

Implemented in CCameraBase< U >.

◆ GetNumberOfComponents()

virtual unsigned MM::Camera::GetNumberOfComponents ( ) const
pure virtual

Returns the number of components in this image. This is '1' for grayscale cameras, and '4' for RGB cameras.

Implemented in CCameraBase< U >.

◆ GetPixelSizeUm()

virtual double MM::Camera::GetPixelSizeUm ( ) const
pure virtual

Returns binnings factor. Used to calculate current pixelsize Not appropriately named. Implemented in DeviceBase.h

Implemented in CCameraBase< U >.

◆ GetROI()

virtual int MM::Camera::GetROI ( unsigned &  x,
unsigned &  y,
unsigned &  xSize,
unsigned &  ySize 
)
pure virtual

Returns the actual dimensions of the current ROI.

◆ GetTags()

virtual void MM::Camera::GetTags ( char *  serializedMetadata)
pure virtual

inlinevirtual

Implements MM::Device.

◆ IsCapturing()

Flag to indicate whether Sequence Acquisition is currently running. Return true when Sequence acquisition is active, false otherwise

Implemented in CCameraBase< U >.

◆ IsExposureSequenceable()

virtual int MM::Camera::IsExposureSequenceable ( bool &  isSequenceable) const
pure virtual

Returns whether a camera's exposure time can be sequenced. If returning true, then a Camera adapter class should also inherit the SequenceableExposure class and implement its methods.

◆ PrepareSequenceAcqusition()

virtual int MM::Camera::PrepareSequenceAcqusition ( )
pure virtual

Sets up the camera so that Sequence acquisition can start without delay

Implemented in CCameraBase< U >.

◆ RemoveTag()

virtual void MM::Camera::RemoveTag ( const char *  key)
pure virtual

Removes an existing tag from the metadata associated with this device These tags will automatically be add to the metadata of an image inserted into the circular buffer

pure virtual

Sets binning factor.

◆ SetExposure()

virtual void MM::Camera::SetExposure ( double  exp_ms)

◆ SetROI()

virtual int MM::Camera::SetROI ( unsigned  x,
unsigned  y,
unsigned  xSize,
unsigned  ySize 
)
pure virtual

Sets the camera Region Of Interest. Required by the MM::Camera API. This command will change the dimensions of the image. Depending on the hardware capabilities the camera may not be able to configure the exact dimensions requested - but should try do as close as possible. If the hardware does not have this capability the software should simulate the ROI by appropriately cropping each frame.

Parameters
x- top-left corner coordinate
y- top-left corner coordinate
xSize- width
ySize- height

◆ SnapImage()

virtual int MM::Camera::SnapImage ( )
pure virtual

Performs exposure and grabs a single image. Required by the MM::Camera API.

SnapImage should start the image exposure in the camera and block until the exposure is finished. It should not wait for read-out and transfer of data. Return DEVICE_OK on success, error code otherwise.

Implemented in CCameraBase< U >.
