### F.2 Verify `RCreateContextWayland()` completeness
|
||||
### F.2 ~~Verify `RCreateContextWayland()` completeness~~ ✅
|
||||
**Status**: DONE — all fields verified correct, no issues.
|
||||
- **File**: `wrlib/context.c:725-775`
|
||||
- **Operation**: Read `RCreateContextWayland()`. Verify it sets all fields that `RConvertImage` and image loaders need: `depth`, `vclass`, `red_offset`, `green_offset`, `blue_offset`, `black`, `white`, `convert_image`, `convert_image_mask`. Verify `dpy`, `cmap`, `copy_gc`, `visual`, `drawable` are NULL/0.
|
||||
- **Test**: Call `RCreateContextWayland(1920, 1080, NULL)`, then `RLoadImage(ctx, "test.png", 0)`, then `RConvertImage(ctx, img, &pixmap)`. Confirm the pixmap is a `pixman_image_t*` cast to `Pixmap`.
|
||||
- **Blocked by**: nothing

|
||||
### F.3 Verify `wl_convert_image` / `wl_convert_image_mask`
|
||||
### F.3 ~~Verify `wl_convert_image` / `wl_convert_image_mask`~~ ✅
|
||||
**Status**: DONE — RGBA→ARGB32 conversion correct, alpha handling correct, no bugs.
|
||||
- **File**: `wrlib/convert_wl.c` (58 lines)
|
||||
- **Operation**: Read the implementation. Verify RGBA→ARGB32 byte order conversion is correct. Verify alpha channel handling for `RRGBFormat` (no alpha) vs `RRGBAFormat`. Verify the returned `Pixmap` is `(Pixmap)(uintptr_t)pixman_image_t*`.
|
||||
- **Test**: Load a PNG with alpha, convert, verify pixel values in the pixman image.
|
||||
- **Blocked by**: F.2

||||
|
||||
### F.4 Verify image format loaders are X11-independent
|
||||
### F.4 ~~Verify image format loaders are X11-independent~~ ✅
|
||||
**Status**: DONE — all 7 loaders verified X11-independent, zero dpy/cmap/visual references.
|
||||
- **Files**: `wrlib/load_png.c`, `wrlib/load_jpeg.c`, `wrlib/load_gif.c`, `wrlib/load_tiff.c`, `wrlib/load_webp.c`, `wrlib/load_ppm.c`, `wrlib/load_xpm_normalized.c`
|
||||
- **Operation**: Confirm each loader takes `RContext*` only for error reporting (or not at all) and returns `RImage*` without touching `ctx->dpy`. Grep each file for `->dpy`, `->cmap`, `->visual`.
|
||||
- **Expected result**: All clean except `load_xpm.c` (uses `XParseColor`).
|
||||
- **Blocked by**: nothing
|
||||
|
||||
### F.5 Provide Wayland-safe XPM loading path
|
||||
### F.5 ~~Provide Wayland-safe XPM loading path~~ ✅
|
||||
**Status**: DONE — already wired up at load.c:199-204 — ctx->dpy==NULL check dispatches to RLoadXPMNormalized.
|
||||
- **File**: `wrlib/load_xpm.c` (180 lines) — uses `XParseColor` for color name→RGB
|
||||
- **Operation**: `load_xpm_normalized.c` (459 lines) already exists as a pure-C XPM parser that doesn't need X11. Verify that `RLoadImage()` in `wrlib/load.c` dispatches to `load_xpm_normalized.c` when `ctx->dpy == NULL`. If not, add a check:

### Phase F Summary
|
||||
|
||||
All five Phase F tasks verified — the wrlib Wayland integration path is **complete with zero code changes required**:
|
||||
|
||||
| Task | Result |
|
||||
|------|--------|
|
||||
| F.1 | Gratuitous `#include <X11/Xlib.h>` in 10 pure files — cosmetic only, accepted per option (b). |
|
||||
| F.2 | `RCreateContextWayland()` — all fields verified correct. depth=32, TrueColor, RGBA offsets, black/white, convert function pointers all set. dpy/cmap/visual/drawable NULL'd. |
|
||||
| F.3 | `wl_convert_image` / `wl_convert_image_mask` — RGBA→ARGB32 byte order correct, alpha handling correct for both RRGBFormat and RRGBAFormat, mask thresholding with stride-aware indexing, Pixmap cast idiomatic. No bugs. |
|
||||
| F.4 | All 7 image format loaders verified X11-independent — zero references to `->dpy`, `->cmap`, `->visual`. |
|
||||
| F.5 | Wayland-safe XPM loading already wired at `load.c:199-204` — `dpy == NULL` check dispatches to `RLoadXPMNormalized` (pure-C parser) vs `RLoadXPM` (X11/XParseColor). |
|
||||
|
||||
Key architecture point: wrlib's `convert_image` function pointer (`context->convert_image`) is the single abstraction seam — set to `wl_convert_image` by `RCreateContextWayland()` and `x11_convert_image` by `RCreateContext()`. Everything else is either pure image manipulation (portable) or hardcoded X11 (`xutil.c`, `xpixmap.c`, `convert_x11.c`) that is dead code on the Wayland path.
