All 5 phases of the open-source Decal rebuild: Phase 1: 14 decompiled .NET projects (Interop.*, Adapter, FileService, DecalUtil) Phase 2: 10 native DLLs rewritten as C# COM servers with matching GUIDs - DecalDat, DHS, SpellFilter, DecalInput, DecalNet, DecalFilters - Decal.Core, DecalControls, DecalRender, D3DService Phase 3: C++ shims for Inject.DLL (D3D9 hooking) and LauncherHook.DLL Phase 4: DenAgent WinForms tray application Phase 5: WiX installer and build script 25 C# projects building with 0 errors. Native C++ projects require VS 2022 + Windows SDK (x86). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# DecalRender.DLL
|
|
|
|
## Origin
|
|
Factored out of the old **Inject.DLL** — the rendering functionality (texture creation,
|
|
font rendering, surface blitting) that previously lived inside Inject was moved into
|
|
this dedicated COM server.
|
|
|
|
## Binary Facts
|
|
- Size: **108 KB**
|
|
- Type: COM in-process server (DLL)
|
|
- Standard 4 COM exports: `DllCanUnloadNow`, `DllGetClassObject`, `DllRegisterServer`, `DllUnregisterServer`
|
|
|
|
## Key Imports
|
|
| DLL | Functions |
|
|
|-----|-----------|
|
|
| **Inject.DLL** | `BeginSceneO`, `EndSceneO` |
|
|
| **d3dx9_30.dll** | `D3DXCreateTexture`, `D3DXLoadSurfaceFromMemory`, `D3DXCreateFontW`, and others |
|
|
|
|
## What It Does
|
|
Provides the 2D rendering layer for Decal's overlay UI — creating textures, loading
|
|
surfaces from memory, and drawing text with DirectX fonts. Inject.DLL hooks the
|
|
Direct3D scene begin/end, and DecalRender plugs into those hooks to draw.
|
|
|
|
## Reconstruction Notes
|
|
- **LOOK AT:** `Managed/Decal.Interop.Render/` for the COM interface definitions
|
|
this DLL must implement. That directory contains **19 decompiled C# files**
|
|
describing every interface, enum, and coclass.
|
|
- **LOOK AT:** The old `Native/Inject/` source for rendering code that was likely
|
|
moved here. Search for anything that touches `IDirect3DTexture9`, `ID3DXFont`,
|
|
surface blitting, etc.
|
|
- The interop assembly will define the exact vtable layout the managed side expects.
|
|
Every COM interface in `Decal.Interop.Render` maps to an interface this DLL exposes.
