ComfyUI Node: ImageResize_Padding

ImageResize_Padding:

The ImageResize_Padding node is designed to resize an image to a specified width and height while optionally adding padding to maintain the original aspect ratio. This node is particularly useful when you need to fit an image into a specific dimension without distorting its content. By adding padding, the node ensures that the image's aspect ratio is preserved, preventing any stretching or squishing. The padding can be customized with specific colors, allowing for a seamless integration of the image into various backgrounds or layouts. This node is ideal for preparing images for further processing or display, ensuring they meet the required dimensions while maintaining their visual integrity.

ImageResize_Padding Input Parameters:

image

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

width

This parameter specifies the target width for the resized image. It determines the final width of the output image after resizing and padding. The value should be an integer representing the number of pixels.

height

This parameter specifies the target height for the resized image. It determines the final height of the output image after resizing and padding. The value should be an integer representing the number of pixels.

padding

This boolean parameter determines whether padding should be added to the image to maintain its aspect ratio. If set to True, the node will calculate and add the necessary padding to ensure the original aspect ratio is preserved.

Red

This parameter specifies the red component of the padding color. It should be an integer between 0 and 255, where 0 represents no red and 255 represents full red.

Green

This parameter specifies the green component of the padding color. It should be an integer between 0 and 255, where 0 represents no green and 255 represents full green.

Blue

This parameter specifies the blue component of the padding color. It should be an integer between 0 and 255, where 0 represents no blue and 255 represents full blue.

interpolation

This parameter specifies the interpolation method used for resizing the image. The default value is "nearest", but other methods like "bilinear" or "bicubic" can be used depending on the desired quality and performance.

ImageResize_Padding Output Parameters:

outputs

This parameter represents the resized and optionally padded image. It is the final output of the node, ready for further processing or display.

width

This parameter represents the width of the output image. It confirms the final width after resizing and padding.

height

This parameter represents the height of the output image. It confirms the final height after resizing and padding.

ImageResize_Padding Usage Tips:

• To maintain the original aspect ratio of your image while fitting it into a specific dimension, set the padding parameter to True.
• Customize the padding color using the Red, Green, and Blue parameters to match the background or layout where the image will be used.
• Experiment with different interpolation methods to find the best balance between quality and performance for your specific use case.

ImageResize_Padding Common Errors and Solutions:

"Invalid image format"

• Explanation: The input image is not in a supported format.
• Solution: Ensure the image is in a compatible format, such as a tensor or array.

"Width and height must be positive integers"

• Explanation: The specified width or height is not a positive integer.
• Solution: Provide positive integer values for both the width and height parameters.

"Padding color values must be between 0 and 255"

• Explanation: The Red, Green, or Blue parameter is outside the valid range.
• Solution: Ensure that the color values are integers between 0 and 255.

"Unsupported interpolation method"

• Explanation: The specified interpolation method is not recognized.
• Solution: Use a valid interpolation method such as "nearest", "bilinear", or "bicubic".
