Image Scale Down By(imageScaleDownBy)

The Image Scale Down By node resizes an input image (or batch of images) by a fractional factor, downsizing its dimensions to a percentage of the original size. It belongs to the EasyUse/Image category.

Inputs

• images (IMAGE, required): The image or batch of images to be scaled down. Each image in the batch is resized using the same factor.
• scale_by (FLOAT, required): The scaling factor applied to the image dimensions. It is a multiplier: a value of 0.5 reduces the image width and height to half their original size, while a value of 1.0 leaves the image unchanged. The accepted range is 0.01 to 1.0, with a default of 0.5 and step size 0.01. Because the maximum allowed value is 1.0, this node only ever scales images down — it cannot upscale them.

Outputs

• IMAGE: The resized image or batch of images, with dimensions scaled down by the given factor.

Usage Notes

• The scale factor applies uniformly to both width and height, preserving the original aspect ratio.
• If you need to upscale an image, use a dedicated upscaling node instead, since this node's scale_by is clamped at 1.0.
• When processing a batch, the output is a new batch where every image has been downscaled to the same resulting dimensions based on the factor.
