For some reason some images with the case 1 format show up transparent as well.

Newer KMS wz introduces a new PNG format--format 257(A1R5G5B5).The new NPCs with IDs starting with 257XXXX.img

PHP Code:


case 257: 
        {
          pngDecoded = new Bitmap(this.w, this.h, PixelFormat.Format16bppArgb1555);
          bmpdata = pngDecoded.LockBits(new Rectangle(Point.Empty, pngDecoded.Size), ImageLockMode.WriteOnly, PixelFormat.Format16bppArgb1555);
          CopyBmpDataWithStride(pixel, pngDecoded.Width * 2, bmpdata);
          pngDecoded.UnlockBits(bmpdata);
          break;
        }
........
........
 public static void CopyBmpDataWithStride(byte[] source, int stride, BitmapData bmpData)
        {
            if (bmpData.Stride == stride)
            {
                Marshal.Copy(source, 0, bmpData.Scan0, source.Length);
            }
            else
            {
                for (int y = 0; y < bmpData.Height; y++)
                {
                    Marshal.Copy(source, stride * y, bmpData.Scan0 + bmpData.Stride * y, stride);
                }
            }

        }
