ComfyUI Node: Match Image Ratio to Standard Size

Match Image Ratio to Standard Size:

The MatchImageRatioToPreset node is designed to help you adjust the aspect ratio of an image to match a predefined set of standard dimensions. This is particularly useful when you need to ensure that your images conform to specific size requirements, such as for printing, web design, or other digital media applications. By comparing the aspect ratio of your input image to a list of preset ratios, the node identifies the closest match and adjusts the image dimensions accordingly. This process helps maintain visual consistency and quality across different images, making it easier to work with standardized formats.

Match Image Ratio to Standard Size Input Parameters:

image

The image parameter is the input image that you want to adjust. This parameter accepts an image file and is essential for the node to perform its function. The image's aspect ratio will be compared to the preset ratios to find the closest match.

width_offset

The width_offset parameter allows you to adjust the width of the matched preset dimension. It accepts integer values ranging from -128 to 128, with a default value of 0. This parameter is useful if you need to fine-tune the width of the output image to better fit your specific requirements.

height_offset

The height_offset parameter allows you to adjust the height of the matched preset dimension. It accepts integer values ranging from -128 to 128, with a default value of 0. Similar to the width_offset, this parameter helps you fine-tune the height of the output image for more precise control over the final dimensions.

Match Image Ratio to Standard Size Output Parameters:

standard_width

The standard_width parameter represents the width of the closest matching preset dimension. This output helps you understand the adjusted width of your image after matching it to the preset ratios.

standard_height

The standard_height parameter represents the height of the closest matching preset dimension. This output provides the adjusted height of your image, ensuring it conforms to the closest preset ratio.

min

The min parameter indicates the smaller value between the standard_width and standard_height. This output is useful for understanding the minimum dimension of the adjusted image, which can be important for certain design or layout considerations.

max

The max parameter indicates the larger value between the standard_width and standard_height. This output helps you understand the maximum dimension of the adjusted image, which can be crucial for maintaining visual consistency and quality.

Match Image Ratio to Standard Size Usage Tips:

• Use the width_offset and height_offset parameters to fine-tune the dimensions of your image, ensuring it fits perfectly within your design requirements.
• When working with a batch of images, apply the same preset ratio to maintain consistency across all images.
• Utilize the min and max output parameters to make informed decisions about image placement and scaling in your projects.

Match Image Ratio to Standard Size Common Errors and Solutions:

Error: "Input image is not provided"

• Explanation: This error occurs when the image parameter is not supplied.
• Solution: Ensure that you provide a valid image file as input to the node.

Error: "Width offset or height offset out of range"

• Explanation: This error occurs when the width_offset or height_offset values are outside the allowed range of -128 to 128. - Solution: Adjust the width_offset and height_offset values to be within the specified range.

Error: "Failed to match aspect ratio"

• Explanation: This error occurs when the node is unable to find a close match for the input image's aspect ratio from the preset list.
• Solution: Verify that the input image has a reasonable aspect ratio and consider adjusting the preset list if necessary.
