CYIImageSceneNode Class Reference

Detailed Description

Provides special resize behaviour typically useful for images.

Image layers in AE are imported as CYIImageSceneNode.

The following properties are supported by the CYIImageSceneNode:

Label Default value Accepted values Description
size-mode stretch stretch, fill, fit, original-size The sizing mode which will be applied when the image node size is larger than the original image texture size.
See also
repeat-mode none none, tile, mirror, clamp The repeat mode which will be applied when the image node size is larger than the original image texture size.
See also
mipmapping false true, false Toggles whether the underlying texture will use mipmapping.

Member Enumeration Documentation

◆ RepeatMode

When the node is resized, the selected repeat mode dictates how 'empty' space is used.

When the scene node is measured and its repeat mode is not CYIImageSceneNode::RepeatMode::None, the reported measured size will always be the incoming measure specs (rather than be based on the image's size and size mode). This differs from the normal behaviour where the measured size would be calculated from the size mode, the incoming measure spec, and the original image size.
The repeat mode has no effect when the size mode is CYIImageSceneNode::SizeMode::Stretch or CYIImageSceneNode::SizeMode::Fill.
To have a visible effect the CYIImageSceneNode size must be greater than the original image texture size as the CYIImageSceneNode size will be initialized to the size of the image texture. This can be accomplished by placing the CYIImageSceneNode in a layout which modifies the contents size. For example placing the CYIImageSceneNode in a CYIStackLayout with the fill-parent property enabled. Programatically setting the CYIImageSceneNode size via SetSize() outside of a layout will also work.
Not all devices support the use of CYIImageSceneNode::RepeatMode::Tile or CYIImageSceneNode::RepeatMode::Mirror with non-power-of-two texture sizes. A power-of-two texture size is a texture which has a height and width that are a power-of-two, for example a 256x128 texture. If a device does not support this and the image has a non-power-of-two texture size the image will not be rendered. It is recommended when using these modes that the image texture width and height are power-of-two.

Default: CYIImageSceneNode::RepeatMode::None


No repeat.


The image is tiled to fill the node's size.


The image is tiled to fill the node's size, but adjacent tiles are mirrored.


The edge pixels of the image are 'stretched' to fill the node's size.

◆ SizeMode

When the node is resized, the selected resize mode dictates how the image appears.

Default: CYIImageSceneNode::SizeMode::Stretch


Will resize the image to the size of the node. The aspect ratio will not be retained.


Will resize on either the width or the height, whichever is larger. The image may be larger than the node size. The aspect ratio of the image will be retained.


Will resize on either the width or the height, whichever is smaller. The image may be smaller than the node size. The aspect ratio of the image will be retained.


The original size and aspect ratio of the image will be retained and the image will be centered in the CYIImageSceneNode. The image may be smaller or larger than the node size.

◆ Init()

virtual bool CYIImageSceneNode::Init ( )

Initializes the scene node. Children of the scene node are also recursively initialized.

Subclasses must call CYISceneNode::Init.

A CYISceneManager must be set on the node using SetSceneManager before the node can be initialized.
The node must have an assigned CYISceneManager before this function can be called.

◆ IsMipmappingEnabled()

bool CYIImageSceneNode::IsMipmappingEnabled ( ) const

◆ Measure()

virtual void CYIImageSceneNode::Measure ( const MeasureSpec widthSpec,
const MeasureSpec heightSpec,
const MeasureSpec depthSpec 

Measures this scene node, considering the layout configuration constraints (if available) and the provided measure specifications. The Measure function is used by the layout system to determine the 'desired' size of elements in a container. The result of calls to this function can be accessed through the GetMeasuredSize() function.

The Measure function may be called multiple times on a single scene node during a layout pass.
The measure specs passed in must take in consideration the node's scale. For example, if a node is calling the Measure function on one of its children and that child has a scale of glm::vec3(1, 3, 1), then the size of heightSpec must be divided by 3.
The measured values may exceed the provided measure specifications if the specifications cannot be met given the constraints placed on this scene node. In other words, the constraints placed on this node have a higher priority than the provided measure specifications.
Subclasses that override this function must ensure that the Measure function of ALL children of this scene node is called at least once, even if those children are hidden.
Typically, if Measure is overridden then ApplyMeasurements must also be overridden.
Subclasses that override this function should make use of the GetCurrentLayoutDirtyFlag() function (rather than GetLayoutDirtyFlag() ).

Reimplemented from CYISceneNode.

◆ RecalculateMesh()

void CYIImageSceneNode::RecalculateMesh ( )

◆ SetImageAlignment()

void CYIImageSceneNode::SetImageAlignment ( const glm::vec2 &  imageAlignment)

Sets how the image should be aligned when a sizing mode is applied.

For the x component of the alignment, a value of 0.0f will align the left edge of the image to the left side of the size, a value of 1.0f will align the right edge of the image to the right side of the size, and a value of 0.5f will center the image horizontally. For the y component of the alignment, a value of 0.0f will align the top edge of the image to the top side of the size, a value of 1.0f will align the bottom edge of the image to the bottom side of the size, and a value of 0.5f will center the image vertically. Values outside of the 0.0f to 1.0f range are accepted and will behave as one might expect.

By default, the image is centered (using an image alignment of glm::vec2(0.5f, 0.5f)).

◆ SetImageScale()

void CYIImageSceneNode::SetImageScale ( const glm::vec2 &  imageScale)

Sets an image scale for this image node. The image scale is an extra scale that is applied on top of the calculated image size for a given sizing mode. By default, the image scale is 1.0.

Setting an image scale when the repeat mode is RepeatMode::None will result in undefined behaviour.

◆ SetMipmappingEnabled()

void CYIImageSceneNode::SetMipmappingEnabled ( bool  enable)

Configures the underlying texture to use mipmapping. Mipmapping is disabled by default.

void CYIImageSceneNode::SetRepeatMode ( RepeatMode  repeatMode)
