AltiumSharp

Reads and writes Altium library files, rendering them with C#. Many thanks to Tiago Trinidad (@Kronal on Discord) for his huge efforts on this library.

Usage

You will need to add a NuGet references to your project for:

• OpenMcdf by ironfede
• System.Drawing.Common (even if it's a command line project)
• System.Text.Encoding.CodePages

Opening a PcbLib File

// open a PcbLib file.
using (var reader = new PcbLibReader(fileName))
{
    // read the file
    reader.Read();

    // iterate through each component in the library
    foreach (var component in reader.Components)
    {
        Console.WriteLine($"{component.Name}, {component.Pads}, {component.Primitives.Count()}");
    }

    // Settings in the header.
    _displayUnit = reader.Header.DisplayUnit;
    _snapGridSize = reader.Header.SnapGridSize;
    _components = reader.Components.Cast<IComponent>().ToList();
}

Read/Write a SchLib File

// open a SchLib file.
string path = @"C:\altium-library\symbols\ARM Cortex";
        string[] files =
            { "SCH - ARM CORTEX - NXP LPC176X LQFP100.SCHLIB", "SCH - ARM CORTEX - NXP LPC176X TFBGA100.SCHLIB", "SCH - ARM CORTEX - NXP LPC176X WLCSP100.SCHLIB" };

        foreach (var file in files)
        {
            using (var reader = new AltiumSharp.SchLibReader())
            {
                var schLib = reader.Read(Path.Combine(path, file));

                // iterate through each component in the library
                foreach (var component in schLib.Items)
                {
                    Console.WriteLine($"{((IComponent)component).Name}, {component.Comment}");
                }

                // write schlib
                using (var writer = new SchLibWriter())
                {
                    writer.Write(schLib, Path.Combine(path, file), true);
                }
            }
        }

Rendering a Component

_renderer = new PcbLibRenderer();

if (_renderer != null)
{
    _renderer.Component = _activeComponent;
    
    if (_pictureBoxImage == null) _pictureBoxImage = new Bitmap(pictureBox.Width, pictureBox.Height);
    using (var g = Graphics.FromImage(_pictureBoxImage))
    {
        _renderer.Render(g, pictureBox.Width, pictureBox.Height, _autoZoom, fastRendering);
    }
    _autoZoom = false;
}
