Class EdgeBlock

Namespace
VisioForge.Core.MediaBlocks.VideoProcessing
Assembly
VisioForge.Core.dll

Edge detection video effect block that highlights object boundaries and structural features. This block applies advanced edge detection algorithms to identify and emphasize edges, contours, and boundaries in video content using gradient analysis and convolution filters. Creates artistic line-art style visuals by converting images to edge-only representations with adjustable sensitivity and threshold parameters. Essential for computer vision applications, artistic video filters, technical analysis, and creative content requiring structural outline visualization. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Methods

Build()

Constructs and initializes the edge filter and its associated GStreamer elements. This method creates the filter for edge detection, establishes input and output pads, and prepares the block for highlighting edges and boundaries using gradient analysis algorithms.

public override bool Build()

Returns

bool

true if the filter was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this edge detection block. This method disposes of the GStreamer elements and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core BaseElement wrapper that provides additional functionality around the GStreamer edge filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer edge filter.

GetElement()

Gets the underlying GStreamer element that performs the edge detection processing.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the edge filter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project.

public static bool IsAvailable()

Returns

bool

true if this media block is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this edge detection block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
