059017188d DrawList: baking half-texel in TexUvLines[] now that AddPolylineLegacy() was removed. 2026-10-07 18:53:54 +02:00

deb9c70ace DrawList: ImDrawFlags_AALineEnds also requires ImDrawFlags_AALine, which makes it easier for widgets to opt-in AAEnds. 2026-10-07 18:53:54 +02:00

20f17eeb6f DrawList: fixed using ImDrawFlags_UseTexForRoundCorners when ImFontAtlasFlags_NoBakedRoundCorners has also been set. 2026-10-07 18:53:54 +02:00

a597beaf95 DrawList: fixed dropping prim flags in some paths (most for ImDrawFlags_AAXXX flags). 2026-10-07 18:53:54 +02:00

ba918bc45c DrawList: fixed filled rect baked AA. 
Always add 1px to the fill side of the rounded corner to prevent the corner AA to bleed into the rectangle edges.

7a510274ce DrawList: Comments. Atlas's NoBakedLines automatically disable AA at Style level. Fix passing non-Legacy stroke mask to PushDrawFlag(). Demo: Custom Rendering: use LiveEdit everywhere. 2026-10-07 18:53:54 +02:00

b220bffdbb Checkbox, Menus: check marks use anti-aliased ends. 
Currently not a satisfying resolution.

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() 
- test overestimate before testing more expensive details when testing if stroked ngon is actualy filled
- Note: not a common function, but the test harness is using this to draw a triangle, which makes it show up in profiling

145b838818 DrawList: Optimize AddRectFilled() 
- detect and draw non-rounded non-AA rect with less branches and calculations
- improves new AddRectFilled() overhead from 30% to 5-10%

c5c76dcda5 DrawList: Optimize _SelectFringeTexture() 
- store inverse line thickness in the spare texture uv component (same v was stord twice) to avoid division in _SelectFringeTexture

b181739cea DrawList: Revert texture selection to simple round() in _SelectFringeTexture 
- revert texture selection to use just (inlined) round()
- the values were tuned to hide texture selection pops on small thickness
- since we're using super sampling for the problematic range, the tweaks are not necessayr anymore

f272141a4d DrawList: merged _AddPolyline back into AddPolyline. 
- AddPolyline used to call different versions of _AddPolyline, the separation is not needed anymore, one less function call in debug mode

9be9c998d7 DrawList: removed vertex offset overflow (for 16-bit ImDrawIdx support) handling. 
This seems unnecessary for now.

478813c359 DrawList: restored non-AA rendering mode. 
- the ImDrawListFlags_AntiAliasedFill and ImDrawListFlags_AntiAliasedLines flags work again
- added non-AA rendering for polyline and convex poly filled
- do not use corner textures when AA is not used
- Add missing no-AA for single line case

a5d8450a0f DrawList: fixed overdraw of transparent rounded rectangles 
- transition earlier to _AddRectTinyRounding() to avoid overdraw issues

2edac09d9f DrawList: fixed baked corners to better match polyline corners 
- added CalcArcStepAndCount() to calculate the step size consistently
- _AddRectTinyRounding: fixed stem placement with thin lines (clamping was needed for an older version of the function)
- _AddRectTinyRounding: fixed texture coordinates (uses if inner/outer were reversed)
- use polygon instead of circle when calculating baked corner rounds (the circle was more accurate but looked different size comparet to polyline)

002e2a5f00 DrawList: added macro to have consistent check for rounding 
- use macro to test if rounding value is worthy
- changed threshold to be a bit smaller (for smoother handling of small radius), and relative to fringe

7ec1bc17fd DrawList: debug build optimizations. 
- changed truncated tests to use macro, and inline the computation in debug builds (~15% was spent on calling the functions)
- inlined the common rectangle cases in AddRect() for debug build speed up

ed8ed8bb71 DrawList: fixed thin lines appearing too bright. 
- fixed how super sampled line textures are generated (and documented wrong assumption)
- switched to more samples and smaller thickness range
- tweaked super sampled texture selection to hide the texture changed better
