The previous code wrote input.Length (character count) instead of Encoding.UTF8.GetBytes(input).Length (byte count). This caused path strings containing non-ASCII characters (e.g., Chinese) to be written with incorrect length prefix, corrupting the PKG header.
- Add net8.0 alongside net472 for cross-platform support - Conditional Microsoft.CSharp reference for net472 only
When source mipmap dimensions differ from header dimensions, resize instead of only cropping. Also handle the case where source is smaller than header dimensions.
- Info.cs: recognize .mpkg files when processing single file input - Info.cs: merge .pkg and .mpkg directory enumeration - Extract.cs: recognize .mpkg files in single file mode - Extract.cs: merge recursive and non-recursive .pkg/.mpkg enumeration
Pack command (repkg pack):
- Directory mode: pack directory to .pkg or .mpkg
- File mode: convert image/gif/video to .tex texture
- Auto-detect magic: .pkg -> PKGV0005, .mpkg -> PKGM0019
- Options: --format, --lz4, --no-gif, --video-width/height
ImageToTexConverter:
- Convert PNG, JPEG, GIF to TEX textures (RGBA8888/R8/RG88)
- Convert GIF animations to multi-frame TEX with frame info
- Convert MP4/WebM/MOV/AVI to video TEX (MP4 wrapped in TEX container)
V4 texture container support:
- TexImageContainerWriter: write V4 header (Format + isVideoMp4 flag)
- TexImageWriter: add WriteMipmapV4 with extra metadata fields
- For non-MP4 V4 containers, fall back to V3 mipmap format (matching
official Wallpaper Engine TEX structure)
- ITexImageWriter interface updated to pass FreeImageFormat
Program.cs: register PackOptions verb for CLI dispatch

Summary
This PR adds a
packcommand for creating.pkg/.mpkgpackages and.textextures from images, GIFs, and video files. It also adds.mpkgextension support to existing commands (info,extract) and fixes a Unicode path bug in the PKG writer.Commits
1. fix: use UTF-8 byte count in WriteStringI32Size
WriteStringI32Sizeusedinput.Length(character count) instead of UTF-8bytes.Length. Non-ASCII filenames (e.g., Chinese) had incorrect length prefix, corrupting PKG headers.2. build: add net8.0 target framework
Dual-target
net472;net8.0for cross-platform compatibility. ConditionalMicrosoft.CSharpreference.3. fix: improve TexToImageConverter crop/resize logic
Handle case where mipmap dimensions are smaller than header dimensions by resizing.
4. fix: support .mpkg extension in info and extract commands
.mpkgfiles in single-file mode (was only.pkg).pkg/.mpkgdirectory enumeration into singleConcatcalls5. feat: add pack command and video TEX support
