Inputs
Outputs

This node performs image scaling by changing the width, height, and pixel sizes of an image. Use this node to resize images into new output canvases that can be of different aspect ratios or resolutions. This node allows for different sampling algorithms such as point sampling, bilinear sampling, and box sampling.

Parameters ¶

Signature

The layer type that the source accepts.

See Signatures for more information.

Canvas ¶

Size Control

The method used to control how resampling is done.

Resolution

Control the number of pixels in the width or height.

Aspect Ratio

Control the ratio between the width and height.

Pixel Size

Control the size of the pixels.

Base Size

The base size to use as the final output’s dimensions.

Parameter

Set the base parameters directly using Base Resolution, Base Aspect Ratio, or Pixel Size.

Size Input

Inherit the base parameters from the size_ref input or, if not wired in, the source input.

Base Resolution

When Size Control is Resolution and Base Size is Parameter, this is the base number of pixels for the final image’s width and height.

Base Aspect Ratio

When Size Control is Aspect Ratio and Base Size is Parameter, this is the base aspect ratio for the final image.

Pixel Size

When Size Control is Pixel Size and Base Size is Parameter, this is the base pixel size for the final image. The base pixel size is square pixels, so this size is for both the width and height of a pixel.

Uniform Scale

The scale to apply to the Base Size.

For Resolution, this scales the number of pixels in both dimensions. For Aspect Ratio, this scales the aspect ratio. For Pixel Size, this scales the pixel’s dimensions.

Resolution Scale

When Size Control is Resolution, this scales the number of pixels in width and height respectively.

Fixed Dimension

When Size Control is Aspect Ratio, this determines which dimension stays constant from the input image. The other dimension changes to match the aspect ratio.

Width

The width matches the input image’s width.

Height

The height matches the input image’s height.

Smaller Dimension

The smaller resolution matches the input image’s smaller resolution.

Larger Dimension

The larger resolution matches the input image’s larger resolution.

Size Scale

When Size Control is Pixel Size, this scales the pixel’s width and height respectively.

Reframe to Destination

Stretches the input image through resampling to conform to the entire boundary of the output and maintains the given pixel size. Specifically, this makes the display window match the data window.

See Data and display windows for more information.

Sampling ¶

Filter

The filter used to sample.

See Filters for more information.

Point

Sets the pixel value to the pixel value of the nearest neighbor.

Bilinear

Sets the pixel value through bilinear interpolation .

Box

Sets the pixel value through a box filter, done by sampling all pixels within a box on the original image’s matching pixel.

Bartlett

Sets the pixel value through interpolating according to a triangular window or a Bartlett window , taking each pixel as a sample of this signal.

Catmull-Rom

Sets the pixel value through a bicubic spline known as the Catmull-Rom spline . This is a special case of the Mitchell-Netravali filter .

Mitchell

Sets the pixel value through a bicubic spline known as the Mitchell-Netravali filter.

B-spline

Sets the pixel value through a bicubic spline known as the B-spline . This is a special case of the Mitchell-Netravali filter.

Stretch Behavior

Determine how the image stretches after the resample operation. Specifically, this determines how to stretch the display window.

Note

If Reframe to Destination is on, this parameter has no effect since the display window doesn’t stretch differently.

Stretch to Fit

Stretches the pixels to fit within the new display window. The display window is scaled naively according to the same scale that the data window is scaled at.

Fit Horizontally

Maintains the original pixel aspect ratio and aspect ratio by scaling the display window’s x dimension in relation to the data window’s x dimension.

Fit Vertically

Maintains the original pixel aspect ratio and aspect ratio by scaling the display window’s y dimension in relation to the data window’s y dimension.

Fit Maximally

Maintains the original pixel aspect ratio and aspect ratio by scaling the display window according to the original image’s data window’s maximal dimension.

Fit Minimally

Maintains the original pixel aspect ratio and aspect ratio by scaling the display window according to the original image’s data window’s minimal dimension.

Inputs ¶
