| 1 | // dear imgui: Renderer Backend for DirectX9 |
| 2 | // This needs to be used along with a Platform Backend (e.g. Win32) |
| 3 | |
| 4 | // Implemented features: |
| 5 | // [X] Renderer: User texture binding. Use 'LPDIRECT3DTEXTURE9' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef! |
| 6 | // [X] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset). |
| 7 | // [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures). |
| 8 | // [X] Renderer: IMGUI_USE_BGRA_PACKED_COLOR support, as this is the optimal color encoding for DirectX9. |
| 9 | // [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'. |
| 10 | |
| 11 | // You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this. |
| 12 | // Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need. |
