Initial implementation of GSK rendering pipeline GSK is conceptually split into two scene graphs: * a simple rendering tree of operations * a complex set of logical layers The latter is built on the former, and adds convenience and high level API for application developers. The lower layer, though, is what gets transformed into the rendering pipeline, as it's simple and thus can be transformed into appropriate rendering commands with minimal state changes. The lower layer is also suitable for reuse from more complex higher layers, like the CSS machinery in GTK, without necessarily port those layers to the GSK high level API. This lower layer is based on GskRenderNode instances, which represent the tree of rendering operations; and a GskRenderer instance, which takes the render nodes and submits them (after potentially reordering and transforming them to a more appropriate representation) to the underlying graphic system.

/**
* GskRenderNodeType:
* @GSK_NOT_A_RENDER_NODE: Error type. No node will ever have this type.
* @GSK_CONTAINER_NODE: A node containing a stack of children
* @GSK_CAIRO_NODE: A node drawing a #cairo_surface_t
gsk: Add gsk_color_node_new()
2016-12-13 02:35:56 +00:00
* @GSK_COLOR_NODE: A node drawing a single color rectangle
gsk: Implement linear gradient render nodes
2016-12-15 04:42:31 +00:00
* @GSK_LINEAR_GRADIENT_NODE: A node drawing a linear gradient
Cosmetic change
2017-09-21 01:16:45 +00:00
* @GSK_REPEATING_LINEAR_GRADIENT_NODE: A node drawing a repeating linear gradient
gsk: Add GskBorderNode The node draws a solid CSS border, which can be used to cover everything but dashed and dotted borders (double, groove, inset, ...). For different border styles, we overlay multiple nodes and set their colors to transparent for sides with non-matching styles.
2016-12-18 17:14:53 +00:00
* @GSK_BORDER_NODE: A node stroking a border around an area
Partially revert GskTexture → GdkTexture rename Excessive use of sed when moving GskTexture to GDK; the GskTextureNode should still live under the GSK namespace.
2017-11-04 15:03:03 +00:00
* @GSK_TEXTURE_NODE: A node drawing a #GdkTexture
gsk: Add GskInsetShadowNode And again lots of shadow code gets copied to GSK. But we're now almost at a stage where widget-factory does not use cairo nodes anymore.
2016-12-19 04:13:42 +00:00
* @GSK_INSET_SHADOW_NODE: A node drawing an inset shadow
gsk: Add GskOutsetShadowNode
2016-12-19 14:39:43 +00:00
* @GSK_OUTSET_SHADOW_NODE: A node drawing an outset shadow
Cosmetic change
2017-09-21 01:16:45 +00:00
* @GSK_TRANSFORM_NODE: A node that renders its child after applying a matrix transform
gsk: Replace gsk_render_node_set_opacity() ... with gsk_opacity_node_new(). Also implement support for opacity in gtk_widget_snapshot() using this new node.
2016-12-13 04:49:57 +00:00
* @GSK_OPACITY_NODE: A node that changes the opacity of its child
gsk: Add GskRepeatNode Also add gtk_snapshot_push_repeat() and use that to draw backgrounds. With that change, CSS background snapshots are created without Cairo nodes.
2017-01-01 18:52:18 +00:00
* @GSK_COLOR_MATRIX_NODE: A node that applies a color matrix to every pixel
* @GSK_REPEAT_NODE: A node that repeats the child's contents
gsk: Add gsk_clip_node_new() The node is a simple clipping node: It does a rectangular clip of its contents.
2016-12-13 08:37:51 +00:00
* @GSK_CLIP_NODE: A node that clips its child to a rectangular area
gsk: Add GskRoundedRect It's essentially a port of GtkRoundedBox to graphene.
2016-12-13 18:02:12 +00:00
* @GSK_ROUNDED_CLIP_NODE: A node that clips its child to a rounded rectangle
gsk: Add GskShadowNode ... and make the icon rendering code use it. This requires moving even more shadow renering code into GSK, but so be it. At least the "shadows not implemented" warning is now gone!
2016-12-18 23:45:35 +00:00
* @GSK_SHADOW_NODE: A node that draws a shadow below its child
gskenums: Fix typo/grammar in GskRenderNodeType doc
2017-08-29 22:10:14 +00:00
* @GSK_BLEND_NODE: A node that blends two children together
* @GSK_CROSS_FADE_NODE: A node that cross-fades between two children
Add a render node for text This is just a wrapper around a PangoGlyphString + PangoFont. Basically, the arguments that are passed to pango_renderer_draw_glyphs.
2017-08-29 21:28:10 +00:00
* @GSK_TEXT_NODE: A node containing a glyph string
gsk: Add a blur node For now, this has just a fallback implementation using the typical box filter approximation.
2017-09-03 03:49:34 +00:00
* @GSK_BLUR_NODE: A node that applies a blur
rendernode: Fix serializing Adding the offset node broke serialization in 2 ways: 1. We store the enum value in the node, so make sure to not change it for existing values 2. The offset node was missing in the deserialization lookup table
2018-03-26 17:41:38 +00:00
* @GSK_OFFSET_NODE: A node that renders its child after applying a 2D translation
gsk: Add GskRenderNodeType For now, this is unused.
2016-12-10 20:42:01 +00:00
*
* The type of a node determines what the node is rendering.
