DDS ImageClass is broken

[derplayer]

DDS class fails to deliver propper images.

Simple Code example (read dds and write as new file):

DDS oldImage = new DDS(fileNode.FullPath);
oldImage.Write(fileNode.RootPath + "\\Dummy\\" + fileNode.RelativPath);

will deliver binary incompatible output, that is unreadable by dds tools.

Same problem with custom BaseImage object creation (read png into baseclass, convert and write to dds format):

object baseimage = Activator.CreateInstance(typeof(PNG), new object[] {  AppDomain.CurrentDomain.BaseDirectory + "Dummy\\test.png" });
BaseImage entry = (BaseImage)baseimage;
DDS image= new DDS(entry);
image.FormatDetails = new DDSFormats.DDSFormatDetails(image.FormatDetails.Format);
image.AlphaSettings = image.AlphaSettings;
image.MipHandling = image.MipHandling;
image.HasTransparency = image.HasTransparency;
image.Write(fileNode.RootPath + "\\Dummy\\" + fileNode.RelativPath);

Microsoft DDS analyse tool (texdiag.exe) fails also to analyse the created dds files:

texdiag.exe analyze test.DDS
Microsoft (R) DirectX Texture Diagnostic Tool
Copyright (C) Microsoft Corp. All rights reserved.

test.DDS FAILED (80070032)

Input file is in this case a 32bit-A8R8G8B8" DDS file (32kb + header)
returned file is much smaller (6kb + header, compression?)
Same also happens with the Texture Converter.

Also: some DDS files are glitched when loaded by sdk: https://vgy.me/pZfOY4.png
