ComfyUI Node: Image Resize Advanced

Image Resize Advanced:

The ImageResizeAdvanced node is designed to provide advanced image resizing capabilities, allowing you to adjust the dimensions of an image with precision and flexibility. This node is particularly useful for AI artists who need to resize images while maintaining quality and aspect ratio. It supports various interpolation methods to ensure the resized image meets your quality expectations. The primary goal of this node is to offer a robust solution for resizing images, whether for preparing data for AI models, creating artwork, or any other application where image dimensions need to be adjusted.

Image Resize Advanced Input Parameters:

image

This parameter represents the input image that you want to resize. It is essential as it provides the source data for the resizing operation. The image should be in a format that the node can process, typically a multi-dimensional array representing pixel values.

width

This parameter specifies the desired width of the resized image. It allows you to set the exact width in pixels. If set to 0, the width will be automatically calculated to maintain the aspect ratio based on the height. The default value is 512, with a minimum of 0 and a maximum defined by the system's maximum resolution.

height

This parameter specifies the desired height of the resized image. Similar to the width parameter, it allows you to set the exact height in pixels. If set to 0, the height will be automatically calculated to maintain the aspect ratio based on the width. The default value is 512, with a minimum of 0 and a maximum defined by the system's maximum resolution.

upscale_method

This parameter determines the interpolation method used for resizing the image. The available options are "nearest-exact", "bilinear", "area", "bicubic", and "lanczos". Each method offers different trade-offs between speed and quality, allowing you to choose the most suitable one for your specific needs.

crop

This parameter specifies the cropping method to be used if the aspect ratio of the resized image does not match the original. The available options are "disabled" and "center". "Disabled" will not crop the image, while "center" will crop the image from the center to fit the desired dimensions.

Image Resize Advanced Output Parameters:

image

The output parameter is the resized image. This image will have the dimensions specified by the width and height parameters, and it will be processed using the selected interpolation and cropping methods. The output image is ready for further processing or use in your projects.

Image Resize Advanced Usage Tips:

• To maintain the aspect ratio of the original image, set either the width or height to 0. This will automatically calculate the other dimension.
• Choose the interpolation method based on your quality requirements. For high-quality results, "lanczos" or "bicubic" are recommended, while "nearest-exact" is faster but may produce lower quality.
• Use the "center" crop method if you need to ensure the resized image fits within specific dimensions without distorting the aspect ratio.

Image Resize Advanced Common Errors and Solutions:

"Invalid image format"

• Explanation: The input image is not in a supported format.
• Solution: Ensure the image is a multi-dimensional array representing pixel values.

"Width and height cannot both be zero"

• Explanation: Both width and height parameters are set to 0, making it impossible to determine the resized dimensions.
• Solution: Set either the width or height to a non-zero value to allow the node to calculate the other dimension.

"Unsupported interpolation method"

• Explanation: The selected interpolation method is not recognized.
• Solution: Choose one of the supported interpolation methods: "nearest-exact", "bilinear", "area", "bicubic", or "lanczos".
