ComfyUI Node: 🔧 Image Resize

🔧 Image Resize+:

The ImageResize+ node is designed to help you easily adjust the dimensions of your images, making it a versatile tool for various image manipulation tasks. Whether you need to scale down a large image to fit a specific size or upscale a smaller image without losing too much quality, this node provides a straightforward solution. By leveraging advanced resizing algorithms, ImageResize+ ensures that your images maintain their visual integrity, even when resized significantly. This node is particularly useful for preparing images for different display formats, optimizing them for web use, or simply adjusting their size to meet specific project requirements.

🔧 Image Resize+ Input Parameters:

image

This parameter accepts the image you want to resize. The image should be in a compatible format that the node can process. The function of this parameter is to provide the source material for the resizing operation.

width

This parameter specifies the desired width of the output image. It accepts integer values with a default of 512, a minimum of 0, and a maximum defined by the system's maximum resolution. Setting this parameter to 0 will maintain the aspect ratio based on the height.

height

This parameter specifies the desired height of the output image. It accepts integer values with a default of 512, a minimum of 0, and a maximum defined by the system's maximum resolution. Setting this parameter to 0 will maintain the aspect ratio based on the width.

upscale_method

This parameter determines the algorithm used for resizing the image. The available options are "nearest-exact", "bilinear", "area", "bicubic", and "lanczos". Each method offers a different balance between speed and quality, with "nearest-exact" being the fastest and "lanczos" providing the highest quality for most images.

crop

This parameter specifies how the image should be cropped if the aspect ratio changes during resizing. The options are "disabled" and "center". "Disabled" will not crop the image, while "center" will crop the image from the center to fit the new dimensions.

🔧 Image Resize+ Output Parameters:

image

The output parameter is the resized image. This image will have the dimensions specified by the width and height parameters, adjusted according to the selected upscale method and crop settings. The resized image maintains as much of the original quality as possible, given the constraints of the resizing operation.

🔧 Image Resize+ Usage Tips:

• For best results when upscaling images, use the "lanczos" method to maintain high quality.
• If you need to maintain the aspect ratio, set either the width or height to 0.
• Use the "center" crop method to ensure the most important part of the image remains in view after resizing.

🔧 Image Resize+ Common Errors and Solutions:

Image dimensions exceed maximum resolution

• Explanation: The specified width or height exceeds the system's maximum resolution.
• Solution: Ensure that the width and height parameters are within the allowed range.

Unsupported image format

• Explanation: The input image is in a format that the node cannot process.
• Solution: Convert the image to a supported format before using the node.

Invalid upscale method

• Explanation: The specified upscale method is not one of the allowed options.
• Solution: Choose an upscale method from the provided list: "nearest-exact", "bilinear", "area", "bicubic", or "lanczos".
