Overview

Base Control: WellLogCanvas
Namespace: Beep.Skia.WellLogs

The WellLogCanvas is the root control for this diagram family. It inherits MaterialControl and provides shared port management, styling, and template methods for all nodes in the family.

This family contains 6 node types.

Node Types

Node Class	Shape	Description
`WellLogModels`	N/A (data layer)	LAS 2.0/3.0 and DLIS/RP66 file parsing. Curve data models, well header, and metadata.
`WellLogCanvas`	Canvas container	Main canvas with depth range, track management, grid display, and zoom/scroll.
`WellLogLayoutEngine`	N/A (layout)	Track layout calculation: widths, headers, depth grids, curve scaling.
`WellLogRenderer`	N/A (rendering)	SkiaSharp-based renderer for curves, fills, lithology patterns, and annotations.
`WellLogBrushLibrary`	N/A (styling)	Pre-built brush/fill patterns for lithology: sandstone, shale, limestone, etc.
`WellLogTemplates`	N/A (templates)	Pre-configured track templates: Gamma Ray, Resistivity, Density, Neutron, Sonic.

Connection Points

Every node in this family exposes connection points (ports) for linking to other nodes. Port positions are computed lazily by LayoutPorts(), which runs when MarkPortsDirty() flags the layout as stale after a move or resize.

Node Class	Input Ports	Output Ports	Extra

`WellLogCanvas`	N/A	N/A	—
`WellLogLayoutEngine`	N/A	N/A	—
`WellLogRenderer`	N/A	N/A	—

Connection Conventions

When building diagrams with this family, follow these conventions:

Depth axis runs from top (shallow) to bottom (deep)
Multiple tracks share the same depth column
Curves are displayed per-track with independent scales

Usage Example

Complete example showing creation, node placement, and connection:

C# Example

// Load LAS file
var lasData = WellLogModels.LoadFromLas("well.las");

// Create canvas
var canvas = new WellLogCanvas
{
    X = 50, Y = 50,
    Width = 800, Height = 600,
    DepthStart = 0,
    DepthEnd = 5000
};

// Configure tracks
var track1 = new WellLogTemplates.GammaRayTrack();
var track2 = new WellLogTemplates.ResistivityTrack();
canvas.AddTrack(track1);
canvas.AddTrack(track2);

// Set data and render
canvas.SetData(lasData);
var renderer = new WellLogRenderer(canvas);
renderer.Render(surface, canvas);
