BLPSharp 0.1.0

BLPSharp (formerly known as SereniaBLPLib)

.NET 8.0+ library for decoding BLP textures. Uses TinyBCSharp for fast texture decompression.

Initially created under the name of SereniaBLPLib by Xalcon & later maintained by hazzik & tomrus88.

Notes

Due to not relying on any specific image library anymore, support for BLPs containing JPEG-encoded data was removed and will throw a NYI exception. If someone wants to add this back without relying on a specific image library, feel free to open a PR.

Sample usage

 using (var fs = File.OpenRead("test.blp"))
 {
 var blp = new BLPFile(fs);
 var pixels = blp.GetPixels(mipmapLevel, out int w, out int h);
 // Pixel handling code, see below!
 }

System.Drawing.Bitmap

 Bitmap bmp = new Bitmap(w, h);
 BitmapData bmpdata = bmp.LockBits(new System.Drawing.Rectangle(0, 0, w, h), ImageLockMode.WriteOnly, PixelFormat.Format32bppArgb);
 Marshal.Copy(pixels, 0, bmpdata.Scan0, pic.Length);
 bmp.UnlockBits(bmpdata);

ImageSharp

 var image = SixLabors.ImageSharp.Image.LoadPixelData<Rgba32>(pixels, w, h);

SkiaSharp

 var bitmap = new SKBitmap(w, h);
 using var pixmap = bitmap.PeekPixels();
 var data = pixmap.GetPixelSpan<byte>();
 pixels.CopyTo(data);
