Overview

A render node for a GdkTexture.

Instance Method Summary

• #filter ⇒ Gsk::ScalingFilter

  Retrieves the GskScalingFilter used when creating this GskRenderNode.

• #initialize(texture, bounds, filter) ⇒ Gsk::TextureScaleNode constructor

  Creates a node that scales the texture to the size given by the bounds using the filter and then places it at the bounds' position.

• #texture ⇒ Gdk::Texture

  Retrieves the GdkTexture used when creating this GskRenderNode.

Constructor Details

#initialize(texture, bounds, filter) ⇒ Gsk::TextureScaleNode

Creates a node that scales the texture to the size given by the bounds using the filter and then places it at the bounds' position.

Note that further scaling and other transformations which are applied to the node will apply linear filtering to the resulting texture, as usual.

This node is intended for tight control over scaling applied to a texture, such as in image editors and requires the application to be aware of the whole render tree as further transforms may be applied that conflict with the desired effect of this node.

Parameters:

• texture (Gdk::Texture) —

  the texture to scale

• bounds (Graphene::Rect) —

  the size of the texture to scale to

• filter (Gsk::ScalingFilter) —

  how to scale the texture

#filter ⇒ Gsk::ScalingFilter

Retrieves the GskScalingFilter used when creating this GskRenderNode.

Returns:

• (Gsk::ScalingFilter) —

#texture ⇒ Gdk::Texture

Retrieves the GdkTexture used when creating this GskRenderNode.

Returns:

• (Gdk::Texture) —
