PdfBox.Net.ImageSharp

PdfBox.Net.ImageSharp

Optional rendering backend that proves the core Java AWT/ImageIO proxy layer can also be backed by SixLabors.ImageSharp.

This package intentionally depends only on SixLabors.ImageSharp 3.1.x. It does not reference SixLabors.ImageSharp.Drawing because the current 3.x Drawing package requires a Six Labors license key during build. ImageSharp remains under the Six Labors split license, so this backend should stay optional and should not become a core dependency without an explicit project licensing decision.

This package currently implements:

• BufferedImage pixel storage through Image<Rgba32>
• Graphics2D basic clear, image draw, and transform operations through ImageSharp pixels
• Image decode/encode for PNG and JPEG through ImageSharp codecs

It intentionally does not yet implement a full PageDrawer equivalent. Calling PDF page rendering with this backend throws a clear NotSupportedException. PdfBox.Net.SkiaSharp remains the complete cross-platform rendering backend.

Install:

dotnet add package PdfBox.Net.ImageSharp

Register the backend once at application startup when you want ImageSharp to back the Java AWT/ImageIO proxy APIs for supported image operations.
