Struct gsk4::BlurNode[][src]

pub struct BlurNode(_);
Expand description

A render node applying a blur effect to its single child.

Implementations

Creates a render node that blurs the child.

child

the child node to blur

radius

the blur radius

Returns

a new RenderNode

Retrieves the child RenderNode of the blur self.

Returns

the blurred child node

Retrieves the blur radius of the self.

Returns

the blur radius

Methods from Deref<Target = RenderNode>

Draw the contents of self to the given cairo context.

Typically, you’ll use this function to implement fallback rendering of RenderNodes on an intermediate Cairo context, instead of using the drawing context associated to a gdk::Surface’s rendering buffer.

For advanced nodes that cannot be supported using Cairo, in particular for nodes doing 3D operations, this function may fail.

cr

cairo context to draw to

Retrieves the boundaries of the self.

The node will not draw outside of its boundaries.

Returns
bounds

return location for the boundaries

Returns the type of the self.

Returns

the type of the RenderNode

Serializes the self for later deserialization via deserialize(). No guarantees are made about the format used other than that the same version of GTK will be able to deserialize the result of a call to serialize() and deserialize() will correctly reject files it cannot open that were created with previous versions of GTK.

The intended use of this functions is testing, benchmarking and debugging. The format is not meant as a permanent storage format.

Returns

a GBytes representing the node.

This function is equivalent to calling serialize() followed by g_file_set_contents().

See those two functions for details on the arguments.

It is mostly intended for use inside a debugger to quickly dump a render node to a file for later inspection.

filename

the file to save it to.

Returns

true if saving was successful
