Attempt a contiguous access on the plane's pixels.

Parameters

[in] basePtr Pointer to the first pixel.

Returns: True if contiguous access is possible, false otherwise.

Exceptions

Does	not throw any exception.

This function will try to get the linear increments in x and y. Then it will analyze the increments and if the image plane's memory is contiguous it will return the base pointer.

inlinenoexcept

Attempt a linear access on the plane's pixels.

Parameters

[in] linearAccessData Data structure receiving the values for accessing the pixels.

Returns: True if linear access is possible, false otherwise.

Exceptions

Does	not throw any exception.

This function scans the image's VPAT for the possibility to access the individual pixels with linear increments in x and y direction. If either of the VPATs are jumbled, it will return false, otherwise the values in LinearAccessData can be used to calculate the address of each pixel.

Exceptions

Any	exception derived from std::exception including CvbException.

Normally this property only needs to be accessed if you want to access the underlying CVB image on the pixel level. Note that VPAT access is one of the slower access modes. If possible, linear access is preferred.
