Configuration

Select a function from the list below.

Icon Name Description / Applications
ChargeImageMemoryPools

Preallocates memory buffers for images.


This may improve performance when many images are created and destroyed in an application.

CheckLicense

Check license for a specified module.

ControlAVX2

Enables or disables AVX2 cpu extension usage by other filters.

ControlImageMemoryPools

Enables or disables deterministic image memory allocator.


This may improve performance when many images are created and destroyed in an application.

ControlParallelComputing

Enables or disables filters multithreading parallelization.

ControlSIMD

Enables or disables SIMD cpu extension (e.g. SSE, AVX2, NEON) usage by other filters. This filter does not affect third party components e.g. camera software, OpenCV.

ControlSSE

Enables or disables SSE cpu extension usage by other filters.

DischargeImageMemoryPools

Releases preallocated image memory buffers.

GetAvailableLicenses

Reads available licenses in the system.

GetComputerID

Gets current Computer ID.


Can be used for creating custom license protection for integrator's applications.

GetLibraryVersion

Gets current library version.

GetThreadLimitInfo

Returns how many threads are possible and a list of threads currently being used.


Makes it easier to diagnose licensing problems related to exceeding the limit of threads.

InitLibrary

Initializes library internals. Should be called before any other function from AVL.


If you do not call this first, initialization will be done in the first iteration, possibly affecting system's performance.

InspectImageMemoryPools

Returns information about allocated image memory buffers. This information can be used for preallocation.

WriteLog

Write log message with selected log level.
