Hermet Park	3eaf110e0a	sw_engine: revised the texture clipping ... previous logic doesn't work if the clipping shape has any inner corners. replace the logic with a intermediate composition approach for stability. - performance can be drop at texture clipping by ~11% - size is reduced by -0.5kb issue: https://github.com/thorvg/thorvg/issues/3520	2025-06-11 22:35:54 +09:00
Hermet Park	b3d73e1568	lottie: do not try matting if the layer has no contents	2025-06-09 22:33:25 +09:00
Hermet Park	a2665cbab7	lottie: fixed a repeater opacity logic ... preserve the target opacity by multiplying, do not overwrite it.	2025-06-09 18:52:05 +09:00
Mira Grudzinska	211fee73e2	lottie: fix precomposition with masking ... A precomposition layer is clipped to its viewport. If the same layer also had a mask that was optimized using clipping, this clip was unintentionally overridden by the viewport clipping. This conflict is now fixed.	2025-05-26 19:26:45 +09:00
Hermet Park	bace6b9e52	lottie: removed undesired embedded option. ... Use local font by default and fall back if no glyphs exist. Co-Authored-By: Mira Grudzinska <mira@lottiefiles.com>	2025-05-15 19:21:24 +09:00
Mira Grudzinska	6e41b44ea1	lottie: fix points calculation for rounded polygon ... Added missing factor. issue: https://github.com/thorvg/thorvg/issues/2629	2025-05-14 21:53:32 +09:00
Mira Grudzinska	24fba7cfae	lottie: add missing delimiter ... \u0003 (\3) can be used as delimiter. Now handled correctly.	2025-05-07 10:53:32 +09:00
Hermet Park	1a332acd37	renderer: revise the pImpl design with a better efficiency ... The following is a redesign that extends the class internally. The main goal is to preserve the characteristics of the pImpl idiom for data encapsulation, while simultaneously reducing the memory allocation overhead typically associated with pImpl. The stragegy is here: Rather than alloc the impl memory inside of the thorvg engine, impl extends the API classes in order to consolidate the memory. size has been decreased by -4kb with optimization=s issue: https://github.com/thorvg/thorvg/issues/3214	2025-04-20 00:07:50 +09:00
Hermet Park	e308d3416a	lottie: code refactoring ... align the internal naming for lottie "ix" properites and its variables	2025-04-10 15:10:33 +09:00
Mira Grudzinska	b304448ef7	lottie: revert "lottie: more precise culling for inverse mattes" ... This reverts commit 7ef3352efa. For mattes of type 'InvAlpha' or 'InvLuma', the matted layer can still be visible regardless of the matte's opacity (unlike 'Alpha' and 'Luma' masks, which cut out the entire layer when opacity = 0). The previously introduced optimization incorrectly assumed that with opacity = 255, the image would not be visible. @Issue: https://github.com/thorvg/thorvg/issues/3375 @Issue: https://github.com/thorvg/thorvg/issues/3380 @Issue: https://github.com/thorvg/thorvg/issues/3381 @Issue: https://github.com/thorvg/thorvg/issues/3382	2025-04-09 11:21:36 +09:00
Jinny You	fbe10255d7	lottie/text: added range selector flags ... Duplicated text document properties (fill color, stroke color, and stroke width) to the text range. If these properties are not defined in the range selector, ThorVG incorrectly overrides them with default values. The correct behavior is to preserve the original values. The added flags address this issue. Co-Authored-By: Hermet Park<hermet@lottiefiles.com>	2025-04-07 17:34:52 +09:00
Jinny You	2b3cdb0d97	lottie: simplify text layout calculation	2025-04-05 02:35:11 +09:00
Hermet Park	93cb33fb8e	lottie: improve the compatiblity ... merge the scene with more accurate condition to allow the evenodd pathes among the lottie render tree.	2025-03-27 14:06:19 +09:00
Hermet Park	e5d55d0651	lottie: safety++ ... Don't apply matte — it's already been pushed into the scene. This is a corner-case bug that occurs when the Lottie data violates the specification.	2025-03-27 12:43:17 +09:00
Hermet Park	fba861cb4f	lottie: fixed a regression bug ... reverted stroke optimization from the previous cullting stragtegy. introduced by d386a5654a	2025-03-27 12:43:11 +09:00
Hermet Park	3136cac6e4	Revert "lottie: minor optimization" ... This reverts commit 51bc7e81f8. note: side effect!	2025-03-26 20:56:24 +09:00
Hermet Park	ffdb30cba2	lottie: don't evaluate local font text again	2025-03-26 12:19:32 +09:00
Hermet Park	51bc7e81f8	lottie: minor optimization ... trim out a group when it has only one child.	2025-03-26 00:28:20 +09:00
Hermet Park	333e65ef7a	renderer: revise the Bounding Box Behavior ... - modify the concept of AABB to apply only to transformed shapes. - transform points before computing the bounding box min/max to obtain a more compact shape region. - trimmming memory by removing the cached matrix, about 36kb of memory has been reduced per paint instance.	2025-03-20 13:26:25 +09:00
Mira Grudzinska	ac080ffabc	lottie: add support for text follow path ... Added support for cases without text grouping and range selector. Co-Authored-By: Hemet Park <hermet@lottiefiles.com> @Issue: https://github.com/thorvg/thorvg/issues/2888	2025-03-12 13:08:26 +09:00
Jinny You	e4834e9190	lottie/text: render carriage return with local font (#3310) ... Added missing carriage return support in local font case. issue: #3301	2025-03-11 13:39:55 +09:00

Jinny You	716311f44f	lottie/text: fix justification in embedded font rendering ... issue: #3266	2025-03-04 15:01:35 +09:00
Hermet Park	d386a5654a	Lottie: optimize rendering performance ... implemented an aggressive culling strategy to eliminate unnecessary renderings if the rendering visuals were hidden by other overlaid opaque fills or strokes this pretty improves the performance for those scenarios when rendering sequences are fragmented by fills/strokes. Performance has been improved ~7% with those cases	2025-02-27 19:05:41 +09:00
Hermet Park	9a79dd0267	lottie: code clean up++	2025-02-26 19:00:16 +09:00
Hermet Park	7ef3352efa	lottie: more precise culling for inverse mattes ... don't do rendering further when the inverse mattes has a fully translucent. This could improve rendering performance in that case.	2025-02-26 12:55:47 +09:00
Hermet Park	c5ca7b4b12	lottie: hotfix a regression ... a regression by the code refactoring: 5b30e2ad65	2025-02-25 18:54:04 +09:00
Hermet Park	66a30b2c50	lottie: fixed a regression bug of a weird artififact observation ... this reverts a logic that was introduced by https://github.com/thorvg/thorvg/pull/3167 this logic change was not necessary thus revert it.	2025-02-24 15:47:09 +09:00
Mira Grudzinska	5b30e2ad65	lottie: prevent trimming in masks ... Until now the fill's trimming was not supported, which allowed masks to function correctly. Introducing trimming for the entire shape caused the mask to be trimmed as well, leading to incorrect results. Co-Authored-By: Hermet Park <hermet@lottiefiles.com>	2025-02-24 15:06:16 +09:00
Mira Grudzinska	b939a60bfa	api: change api name strokeTrim() -> trimpath() ... No changes in behaviour so far.	2025-02-24 15:05:38 +09:00
Jinny You	646e35484f	loaders: added lottie, svg font fallback mechanism ... fallback for allowing any available fonts. Co-Authored-By: Hermet Park <hermet@lottiefiles.com>	2025-02-20 18:47:01 +09:00
Hermet Park	b77f3ca024	common: introduced designated memory allocators ... Support the bindings to be more integrable with a system's coherent memory management. Pleaes note that thorvg now only allow the desinated memory allocators here: malloc -> tvg::malloc calloc -> tvg::calloc realloc -> tvg::realloc free -> tvg::free issue: https://github.com/thorvg/thorvg/issues/2652	2025-02-18 17:20:31 +09:00
Mira Grudzinska	ad261731b6	lottie: parsing embedded fonts data (#3220) ... Only parsing and font loading is added with a very basic text update while building the scene. @Issue: https://github.com/thorvg/thorvg/issues/3184	2025-02-14 15:52:10 +01:00
Hermet Park	305da05b1b	lottie: resolved minor memory leaks	2025-02-14 00:31:14 +09:00
Mira Grudzinska	391777091c	lottie: ++ dashed stroke support ... Until now lottie loader supported only a single dash-gap pair, and only the case where only the dash was provided was handled correctly. When both values were provided, the gap was incorrectly increased by the dash value. If more values were supplied, only the last pair was considered. @Issue: https://github.com/thorvg/thorvg/issues/3191	2025-02-13 23:37:32 +09:00
Fabian Blatz	71bb4163ed	common: fixed double-precision promotion compilation warnings ... Co-Authored-By: Hermet Park <hermet@lottiefiles.com>	2025-02-12 20:23:34 +09:00
Hermet Park	cc4c18d6c6	renderer: revise the Shape rect/circle features ... The path direction of shapes is now functional for path trimming. Replace the main logic with Lottie's by default to align the spec, migrate the original logic to svg loader side. This revision helps to reduce the binary size by 2–3 KB for lottie loader. API Modifications: - Result Shape::appendRect(float x, float y, float w, float h, float rx = 0, float ry = 0) -> Result Shape::appendRect(float x, float y, float w, float h, float rx = 0, float ry = 0, bool cw = true) - Result Shape::appendCircle(float cx, float cy, float rx, float ry) -> Result Shape::appendCircle(float cx, float cy, float rx, float ry, bool cw = true) - TVG_API Tvg_Result tvg_shape_append_circle(Tvg_Paint* paint, float cx, float cy, float rx, float ry) -> TVG_API Tvg_Result tvg_shape_append_circle(Tvg_Paint* paint, float cx, float cy, float rx, float ry, bool cw) - Tvg_Result tvg_shape_append_rect(Tvg_Paint* paint, float x, float y, float w, float h, float rx, float ry) -> Tvg_Result tvg_shape_append_rect(Tvg_Paint* paint, float x, float y, float w, float h, float rx, float ry, bool cw) issue: https://github.com/thorvg/thorvg/issues/3179	2025-02-12 01:41:02 +09:00
Hermet Park	78cfc33f4c	lottie: support frame tweening feature ... frame tweening allows user to interpolate two frames over a speicified duration. This Tweening functionality can be particularly powerful when combined with state-based (a.k.a. Marker) animation playback in Lottie. For example, apps support state machine based animations, where the transition sequences between states are not linear and can occur in highly irregular directions. Experimental APIs: - Result LottieAnimation::tween(float from, float to, float progress) - Tvg_Result tvg_lottie_animation_tween(Tvg_Animation* animation, float from, float to, float progress)	2025-02-06 19:09:27 +09:00
