Pull Request Overview
This PR updates the C API to use opaque pointer types for all Tvg_* objects, improving encapsulation and clarity.
- Changed all
typedef struct _Tvg_Xdeclarations to pointer types (typedef struct _Tvg_X* Tvg_X) - Updated function signatures in headers and implementations to accept handles (
Tvg_X) instead of pointers-to-pointers - Adjusted example code to declare handles directly and removed unnecessary indirection

| src/bindings/capi/tvgCapi.cpp | Updated all C API functions to use opaque pointer types |
| src/bindings/capi/thorvg_capi.h | Changed typedefs and function declarations for handles |
| examples/Capi.cpp | Refactored example code to use new opaque handle usage |

- The variables
color_stops2_getandcntare not declared in this scope. You likely meant to passcolor_stops2and the count3(or a named count variable).
tvg_gradient_set_color_stops(grad_stroke, color_stops2_get, cnt);
examples/Capi.cpp:145
- Typo in comment: "Prapare" should be "Prepare".
//Prapare a dash for the stroke
src/bindings/capi/thorvg_capi.h:444
- The doc comment above this signature still refers to
canvasas a pointer. Update parameter descriptions (@param canvas) and return-value notes to reflect thatcanvasis now an opaque handle, not a pointer-to-pointer.
TVG_API Tvg_Result tvg_swcanvas_set_target(Tvg_Canvas canvas, uint32_t* buffer, uint32_t stride, uint32_t w, uint32_t h, Tvg_Colorspace cs);

API breaks, but abstracts & simplifies the interface. Let's carefully confirm. |
