The Resize Image/Mask node provides multiple methods to change the dimensions of an input image or mask. It can scale by a multiplier, set specific dimensions, match the size of another input, or adjust based on pixel count, using various interpolation methods for quality.

Inputs

Parameter	Data Type	Required	Range	Description
input	IMAGE or MASK	Yes	N/A	The image or mask to be resized.
resize_type	COMBO	Yes	SCALE_BY SCALE_DIMENSIONS SCALE_LONGER_DIMENSION SCALE_SHORTER_DIMENSION SCALE_WIDTH SCALE_HEIGHT SCALE_TOTAL_PIXELS MATCH_SIZE	The method used to determine the new size. The required parameters change based on the selected type.
multiplier	FLOAT	No	0.01 to 8.0	The scaling factor. Required when resize_type is SCALE_BY (default: 1.00).
width	INT	No	0 to 8192	The target width in pixels. Required when resize_type is SCALE_DIMENSIONS or SCALE_WIDTH (default: 512).
height	INT	No	0 to 8192	The target height in pixels. Required when resize_type is SCALE_DIMENSIONS or SCALE_HEIGHT (default: 512).
crop	COMBO	No	"disabled" "center"	The cropping method to apply when dimensions don’t match the aspect ratio. Only available when resize_type is SCALE_DIMENSIONS or MATCH_SIZE (default: “center”).
longer_size	INT	No	0 to 8192	The target size for the longer side of the image. Required when resize_type is SCALE_LONGER_DIMENSION (default: 512).
shorter_size	INT	No	0 to 8192	The target size for the shorter side of the image. Required when resize_type is SCALE_SHORTER_DIMENSION (default: 512).
megapixels	FLOAT	No	0.01 to 16.0	The target total number of megapixels. Required when resize_type is SCALE_TOTAL_PIXELS (default: 1.0).
match	IMAGE or MASK	No	N/A	An image or mask whose dimensions the input will be resized to match. Required when resize_type is MATCH_SIZE.
scale_method	COMBO	Yes	"nearest-exact" "bilinear" "area" "bicubic" "lanczos"	The interpolation algorithm used for scaling (default: “area”).

Note: The crop parameter is only available and relevant when the resize_type is set to SCALE_DIMENSIONS or MATCH_SIZE. When using SCALE_WIDTH or SCALE_HEIGHT, the other dimension is automatically scaled to maintain the original aspect ratio.

Outputs

Output Name	Data Type	Description
resized	IMAGE or MASK	The resized image or mask, matching the data type of the input.
