ComfyUI Node: Image Resize to 8x

Image Resize to 8x:

The ImageResizeTo8x node is designed to resize images to dimensions that are multiples of 8, ensuring compatibility with various image processing and machine learning models that require such dimensions. This node can either resize, crop, or pad images to achieve the desired dimensions, making it a versatile tool for preparing images for further processing. By ensuring that the image dimensions are multiples of 8, you can avoid potential issues with model compatibility and improve the efficiency of subsequent image processing tasks.

Image Resize to 8x Input Parameters:

image

This parameter represents the input image that you want to resize. The image should be in a format that the node can process, typically a tensor or array representing the pixel values.

mask

This optional parameter represents a mask image that can be resized along with the main image. The mask is used to preserve certain areas of the image during the resizing process.

action

This parameter determines the type of resizing action to be performed. It can be set to resize only, crop to ratio, or pad to ratio. The resize only option will simply resize the image to the nearest multiple of 8, while crop to ratio and pad to ratio will adjust the image dimensions by cropping or padding, respectively, to maintain a specific aspect ratio.

smaller_side

This parameter specifies the target size for the smaller side of the image. It is used in conjunction with the resize only action to determine the new dimensions of the image.

larger_side

This parameter specifies the target size for the larger side of the image. It is used in conjunction with the resize only action to determine the new dimensions of the image.

scale_factor

This parameter determines the scaling factor to be applied to the image. It is used to resize the image by a specific factor, either upscaling or downscaling it.

resize_mode

This parameter specifies the mode of resizing. It can be set to reduce size only or increase size only. The reduce size only mode will only downscale the image, while the increase size only mode will only upscale the image.

side_ratio

This parameter specifies the aspect ratio to be maintained during the resizing process. It is used in conjunction with the crop to ratio and pad to ratio actions to ensure that the resized image maintains the desired aspect ratio.

crop_pad_position

This parameter determines the position for cropping or padding the image. It is used to specify where the cropping or padding should be applied, allowing for more control over the final image dimensions.

pad_feathering

This parameter specifies the amount of feathering to be applied to the padding. Feathering helps to blend the padded areas with the original image, creating a smoother transition.

mask_optional

This optional parameter allows you to specify whether the mask should be used during the resizing process. If set to True, the mask will be resized along with the main image.

all_size_8x

This parameter determines whether all dimensions of the image should be resized to multiples of 8. It can be set to enable or disable. When enabled, the node will ensure that both the width and height of the image are multiples of 8.

target_width

This parameter specifies the target width for the resized image. It is used to set a specific width for the image, overriding other resizing parameters.

target_height

This parameter specifies the target height for the resized image. It is used to set a specific height for the image, overriding other resizing parameters.

Image Resize to 8x Output Parameters:

image

The resized image with dimensions that are multiples of 8. This output image is ready for further processing or use in machine learning models.

mask

The resized mask image, if provided as an input. The mask will have the same dimensions as the resized image, ensuring consistency between the image and mask.

Image Resize to 8x Usage Tips:

• Use the resize only action when you simply need to adjust the image dimensions to the nearest multiple of 8 without changing the aspect ratio.
• Utilize the crop to ratio or pad to ratio actions when you need to maintain a specific aspect ratio while resizing the image.
• Adjust the crop_pad_position parameter to control where the cropping or padding is applied, allowing for more precise control over the final image dimensions.
• Enable the all_size_8x parameter to ensure that both the width and height of the image are multiples of 8, which can be important for certain models and processing tasks.

Image Resize to 8x Common Errors and Solutions:

Image dimensions not a multiple of 8

• Explanation: The input image dimensions are not multiples of 8, which can cause issues with certain models and processing tasks.
• Solution: Use the ImageResizeTo8x node to resize the image to dimensions that are multiples of 8.

Mask dimensions do not match image dimensions

• Explanation: The mask image dimensions do not match the dimensions of the main image, causing inconsistencies during processing.
• Solution: Ensure that the mask image is resized along with the main image using the mask parameter.

Invalid resize mode

• Explanation: The specified resize_mode is not valid, causing the node to fail.
• Solution: Check the resize_mode parameter and ensure it is set to either reduce size only or increase size only.

Invalid action type

• Explanation: The specified action type is not valid, causing the node to fail.
• Solution: Check the action parameter and ensure it is set to resize only, crop to ratio, or pad to ratio.
