Old network
As of Houdini 20.5, use Copernicus nodes instead of Compositing nodes. Though both networks still exist, the Compositing network is now designated as COP Network - Old. The Compositing network and its nodes will be deprecated and then removed in a future Houdini release.
This operation changes the resolution of the image. The contents of the image are scaled appropriately. The aspect ratio may be optionally preserved.
Scale does not affect the cook resolution of its Inputs.
Note
As Scale affects the resolution of the image sequence, its parameters cannot be animated (if animation is desired, use a Transform COP’s scale parameter).
Parameters ¶
Scale
Specifies the scaling method:
To Resolution
Scales to the specified number of pixels.
To Fraction
Scales to a fraction (e.g. 0.5 = 50%)
To Aspect Ratio
Scales to a given Pixel Aspect ratio.
To Second Input’s Resolution
Scales to match the resolution of the second input.
To a Fraction of the Second Input
Scales to match the resolution of the second input scaled by a fraction (e.g. 0.5 = 50%).
To Second Input’s Aspect Ratio
Scales to match the second input’s aspect ratio.
Image Size
Specify the size the image should be scaled to (in Pixels).
Image Fraction
Specify the size you'd like to scale the image as a fraction (e.g. 0.5 = 50%).
Pixel Aspect
Pixel Aspect is the ratio of the width to the height. Specify the pixel aspect ratio to scale the image by here.
Preserve Aspect Ratio
When enabled, it preserves the ratio of the image width to height when scaling.
Image Filter
Specifies the type of filter to use when scaling. The Box filter is the fastest; for almost all uses, the Gaussian is the best choice; use Catmull when you need something a bit sharper than Gaussian.
