Sergii Liebodkin	149acea6a4	wg/gl: add composition blend mode ... Set the scene to use Composition mode so that it generates a pre-composition image, and then normal blend with destination. see also: https://github.com/thorvg/thorvg/pull/3621	2025-07-25 14:44:33 +09:00
Hermet Park	da05042b53	engines: ++TODO ... some blends are not supported yet	2025-07-25 14:33:17 +09:00
Jinny You	bdccfb2449	renderer: support duplicate effects ... implement effect duplication functionality to enable proper Scene duplication with effects. issue: https://github.com/thorvg/thorvg/issues/3631 Co-Authored-By: Hermet Park <hermet@lottiefiles.com>	2025-07-25 12:28:35 +09:00
Sergii Liebodkin	9369642642	gl_engine: fix FBO validation ... At the moment, we use the value GL_INVALID_VALUE to mark an invalid handle for FBO, which is not correct. It is more correct to use the value 0, which signals that the buffer was not created. Canvas initialization processes have also been adjusted.	2025-07-24 21:46:48 +09:00
Hermet Park	7730f8ba8b	renderer: properly support stroke bounding box after scaling. ... The stroke bounding box in ThorVG was previously only approximated, as the stroke transformation was mistakenly omitted. This has now been enhanced. The stroke join/corner is still not taken into account in the bounding box computation...	2025-07-24 19:08:43 +09:00
Hermet Park	0cb903c711	example: updated BoundingBox ... take cover the stroke + matrix use-case.	2025-07-24 19:08:43 +09:00

Hermet Park	7fc8e616da	sw_engine: support hue, color, saturation, luminosity, hardmix blends ... - Hue: Creates a result color with the luminance and saturation of the base color and the hue of the blend color. - Color: Creates a result color with the luminance of the base color and the hue and saturation of the blend color. This preserves the gray levels in the image and is useful for coloring monochrome images and for tinting color images. - Luminosity: reates a result color with the hue and saturation of the base color and the luminance of the blend color. This mode creates the inverse effect of Color mode. - Saturation: Creates a result color with the luminance and hue of the base color and the saturation of the blend color. Painting with this mode in an area with no (0) saturation (gray) causes no change. - HardMix: Adds the bottom & top. If the resulting sum for a channel is 255 or greater, it receives a value of 255; if less than 255, a value of 0. issue: https://github.com/thorvg/thorvg/issues/2701	2025-07-23 18:47:32 +09:00
Sergii Liebodkin	bada5691bc	wg_engine: tessellator optimization ... 1. new tesseletor and stroker are used: less vertexes generated In general, the previous implementation was based on the path-outline-mesh approach. It has now been changed to a path-mesh approach, so we skip the path-outline transformation. For shape fills, a BW-tesselator now used, and all submeshes (moveTo) are stored in a single buffer. For strokes, all intermediate operations such as trimming and dash use path-path logic instead of outline-outline logic. In addition, the new stroker generates fewer polygons for joints, especially for Rounds 2. render all sub-shapes by single draw call https://github.com/thorvg/thorvg/issues/3557 https://github.com/thorvg/thorvg/issues/3288 https://github.com/thorvg/thorvg/issues/3273	2025-07-23 15:38:36 +09:00

Hermet Park	930de44359	api: Add Composition blend mode ... The composition mode enables intermediate blending. When a scene uses Composition mode, it generates an intermediate buffer to render the scene image first. This image can then be blended with the canvas afterward. Please avoid to use this, unless you really need to composite the precomposite scene. This feature is relatively expensive at performance.

Sungun No	3ca2c0edfd	gl_engine: Fix GlRenderTarget reset function ... - Avoid deleting the framebuffer when mFbo == GL_INVALID_VALUE, as this is not a valid framebuffer object.	2025-07-21 11:22:07 +09:00
Hermet Park	a79f9788c1	common: code cleanup++ ... - Use RenderPath common interfaces instead of direct array manipulations. - Replace multiple scalar operations with Point utility operations where applicable.	2025-07-18 23:06:26 +09:00
Sergii Liebodkin	d85952b252	renderer: refactored to share gl stroke dasher among engines ... Move stroke dasher to the common code space to create an abillity to use it on the cross API renderers (wg and gl). Stroke dasher is a path-to-path operation, same as path trim, so can be placed to the common space. Now RenderShape can generate dashed path by itself. Dashing mechanics fully hiden from the user but can be used in gl and wg renderers. issue: https://github.com/thorvg/thorvg/issues/3557 Co-Authored-By: Hermet Park <hermet@lottiefiles.com>	2025-07-18 15:21:33 +09:00
Mira Grudzinska	d8bbb0df31	svg: fix nested use nodes ... Previously, only single-level <use> references were supported. If a <use> node pointed to another element that itself contained a <use> node, the reference wasn’t resolved. This has been fixed by replacing the array of postponed elements with a list. The list is traversed, and nodes aren’t cloned while they or any of their children remain unresolved. In such cases, the target element also gets added to the list, enabling recursive resolution of nested href references. issue: https://github.com/thorvg/thorvg/issues/3615	2025-07-18 11:10:51 +09:00
