System

Asserts that two images are equal or differ by a small given margin.

Writes bytes from a byte buffer to a file.

Check license for a specified module.

Enables or disables deterministic image memory allocator.

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

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.

Releases preallocated image memory buffers.

Gets current Computer ID.

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

Gets current library version.

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.

Verifies a project ID.

This tools is useful for system integrators who need verification if a system is used with a license coming from a legitimate source.

Enumerates the avdata files present in a disk directory and sorts them according to the specified order and loads an object from a file.

Enumerates the files present in a disk directory sorted randomly.

Creates a directory tree if it does not exist.

Returns CRC checksum of the input file.

Returns files of the input directory.

Removes files older than the specified date/time from a directory.

Removes single file.

Splits a file path into a file name and a parent directory

Checks if a given directory is empty.

Checks if the size of the file is equal to zero.

Sends an image to a remote server using FTP (File Transfer Protocol).

Converts text from URL friendly text to a string.

Sends a DELETE request to server and receives a text answer.

Sends a GET request to server and receives a text answer.

Sends a PATCH request to the server and receives a text answer.

Sends a PATCH request in JSON format to the server and receives a text answer.

Sends a POST request to the server and receives a text answer.

Sends a PUT request to the server and receives a text answer.

Sends a PUT request in JSON format to the server and receives a text answer.

Adds or updates an INI value in the specified section & key.

Adds a new section.

Gets all key names within a section.

Gets all values within a section & key.

Gets value from section & key.

Gets value from section & key.

Saves an INI file.

Loads data from a DXF file as an image.

Loads entities from a file of one of available types as an array of points in 3D.

Loads entities from a file of one of available types as an array of points in 3D and an image. Assumes an unordered grid with possible holes.

Sets format parameters of JSON data.

Closes a connected Modbus socket gracefully.
