How Can I Speed Up Bitmap to BitmapSource Conversion in WPF?

Boosting Bitmap Conversion for Seamless WPF Image Rendering

Smooth image display is crucial for high-performance WPF applications. A common performance bottleneck arises from converting Bitmap objects to BitmapSource. While CreateBitmapSourceFromHBitmap offers a simple solution, it's often too slow for optimal performance.

A Superior Solution: Direct Pixel Manipulation

For significantly faster conversion without sacrificing image quality, consider direct pixel mapping. This technique bypasses internal image processing for remarkable speed gains.

<code class="language-csharp">public static BitmapSource Convert(System.Drawing.Bitmap bitmap)
{
    var bitmapData = bitmap.LockBits(
        new System.Drawing.Rectangle(0, 0, bitmap.Width, bitmap.Height),
        System.Drawing.Imaging.ImageLockMode.ReadOnly, bitmap.PixelFormat);

    var bitmapSource = BitmapSource.Create(
        bitmapData.Width, bitmapData.Height,
        bitmap.HorizontalResolution, bitmap.VerticalResolution,
        PixelFormats.Bgr24, null,
        bitmapData.Scan0, bitmapData.Stride * bitmapData.Height, bitmapData.Stride);

    bitmap.UnlockBits(bitmapData);

    return bitmapSource;
}</code>

This code directly copies pixel data, utilizing unsafe code and efficient memory management for extremely fast conversion. This minimizes CPU load, resulting in a noticeable performance improvement for your WPF applications. Implement this optimized method today to experience the benefits of accelerated image rendering.
