Public Functions Documentation#

function CGrabResultImageT#

inline CGrabResultImageT(
    GrabResultT grabResult,
    bool isUnique
)

Creates a grab result image object.

Parameters:

grabResult A grab result.
isUnique User provided info whether the buffer is referenced only by this grab result.

Error Safety:

Does not throw C++ exceptions.

function ~CGrabResultImageT#

inline virtual ~CGrabResultImageT()

Destroys a grab result image object.

function IsValid#

inline virtual bool IsValid() const

Can be used to check whether an image is valid.

Return: Returns false if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::IsValid

function GetPixelType#

inline virtual EPixelType GetPixelType() const

Get the current pixel type.

Return: Returns the pixel type or PixelType_Undefined if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetPixelType

function GetWidth#

inline virtual uint32_t GetWidth() const

Get the current number of columns in pixels.

Return: Returns the current number of columns in pixels or 0 if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetWidth

function GetHeight#

inline virtual uint32_t GetHeight() const

Get the current number of rows.

Return: Returns the current number of rows or 0 if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetHeight

function GetPaddingX#

inline virtual size_t GetPaddingX() const

Get the number of extra data bytes at the end of each row.

Return: Returns the number of extra data bytes at the end of each row or 0 if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetPaddingX

function GetOrientation#

inline virtual EImageOrientation GetOrientation() const

Get the vertical orientation of the image in memory.

Return: Returns the orientation of the image or ImageOrientation_TopDown if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetOrientation

function GetBuffer#

inline virtual void * GetBuffer()

Get the pointer to the buffer.

Return: Returns the pointer to the used buffer or NULL if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetBuffer

function GetBuffer#

inline virtual const void * GetBuffer() const

Get the pointer to the buffer containing the image.

Return: Returns the pointer to the used buffer or NULL if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetBuffer

The buffer is at least as large as the value returned by GetImageSize().

function GetImageSize#

inline virtual size_t GetImageSize() const

Get the size of the image in bytes.

Return: Returns the size of the image in bytes or 0 if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetImageSize

function IsUnique#

inline virtual bool IsUnique() const

Indicates that the referenced buffer is only referenced by this image.

Return: Returns true if the referenced buffer is only referenced by this image. Returns false if the image is invalid.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::IsUnique

function GetStride#

inline virtual bool GetStride(
    size_t & strideBytes
) const

Get the stride in bytes.

Parameters:

strideBytes The stride in byte if it can be computed.

Return: Returns true if the stride can be computed.

Error Safety:

Does not throw C++ exceptions.

Reimplements: Pylon::CPylonImageBase::GetStride

The stride in bytes can not be computed for packed image format when the stride is not byte aligned. See also Pylon::IsPacked(). The stride in bytes can not be computed if the image is invalid.

Protected Attributes Documentation#

variable m_grabResult#

GrabResultT m_grabResult;

The grab result that is adapted to IImage.

variable m_isUnique#

bool m_isUnique;

User provided info whether the buffer is referenced only by this adapter.
