391f714c37 RenderArrow doesn't need 64-bits rounding. Added ImRoundPositive() for consistency. 2026-10-30 19:54:08 +01:00

048d7e10b5 Style: made default arrow stroked. Added SymbolArrowSizeFactor, SymbolArrowThicknessFactor to style arrow. (#5233, #2431, #2235, #6730, #8243) 
Internal function takes a angle: #5812.
This doesn't cover generic rendering override for symbols: #8243, #2431 (arrows, somehow less needed now), #3351 (checkmarks), #6730 (tree nodes)

In the absence of a better standardized symbol/icon design this seem more consistent.

b2ade5f3ad DrawList: AddRectFilled: add support for ImDrawFlags_StrokeLegacy to handle inverted coordinates + non-AA path. 
Fix cases 207 and 251 in testbed.
+ add braces near an IM_APPEND_TRI() to silence PVS-Studio reasonable warning "V640  The code's operational logic does not correspond with its formatting"

3dbb849acf DrawList: fixed PathArcTo to not emit small segments. 
- Changed PathArcTo to select start/end sample in quatized multiples of arc fast sample count
- This is done in order to avoid small segments at the start and end of the path, which causes issues with line AA ends
- Renamed CalcArcStepAndCount to CalcCornerArcStepAndCount to make it more clear that it returns the values for 90 degree arc

c6c352f77d DrawList: fixed too many detailed line textures being created. 
Fixed issue where were creating detailed line textures up to detailed witdh + 1
Changed IM_DRAWLIST_TEX_LINES_DETAILED_WIDTH_MAX to IM_DRAWLIST_TEX_LINES_DETAILED_WIDTH_COUNT which no accounts for all the detailed line textures.

91dc4f456a DrawList: fixed rendering issues on small and degenerate shapes. 
The "does stroke cover the whole shape" used to be overly pessimistic to stroking artifacts. This was due to the fringe, where the geometry would mess up before visually closing the shape.
Fixed the issue by adding max inner offest for the AddPolyline(), which limits the inner offset and also adjusts the texture coords.
Second part of the fix was to calculate the pass the max inner offset from the common shapes (circle, ngon, ellipse, rect).
While this does not fix all the ellipse rendering issues, it limits the issue a lot.
e.g. AddRect() w/ size=5, thickness=2 used to trigger AddRectFilled() fallback because threshold was pessimistic to prevent the AddPolyline() issues.

475660f53c DrawList: fixed overdraw issue for filled baked corner rendering. 
Require all corners to fit inside the rect to avoid overdraw (or fallback to path rendering).
eg. AddRectFilled() w/ size=10, rounding=8 or 10 would break.

7e87cb984d DrawList: consistently support scope flags (ImDrawFlags::Flags) + primitive flags. 
ImDrawFlags_AAEnds and ImDrawFlags_StrokeLegacy ok. (the most important ones).
ImDrawFlags_UseTexForRoundCorners ok.
ImDrawFlags_AAFill, ImDrawFlags_AAStrokes: for primitives: only for selected ones taking flags params. Haven't added the flag to all functions because it feels like a fringe use case.
ImDrawFlags_TextNoPixelSnap supported in RenderText(), per-prim (9417)

10aa5d92e6 DrawList: Optimize AddNgon()
