ComfyUI Node: Width and height for scaling image to ideal resolution 🪴

Width and height for scaling image to ideal resolution 🪴:

The "Width and height for scaling image to ideal resolution 🪴" node is designed to help you resize images to a target resolution that is optimal for your needs. This node calculates the ideal width and height for an image based on a specified target size, ensuring that the image maintains its aspect ratio while being scaled to a resolution that is a multiple of a specified value. This is particularly useful for AI artists who need to prepare images for various applications, ensuring that the images are not only visually appealing but also technically suitable for further processing or display. By using this node, you can achieve a balance between image quality and computational efficiency, making it an essential tool for image scaling tasks.

Width and height for scaling image to ideal resolution 🪴 Input Parameters:

image

This parameter represents the input image that you want to scale. It is the source image whose dimensions will be adjusted to meet the target resolution requirements. The image should be provided in a format that the node can process, typically as a tensor or array.

target_size

The target_size parameter specifies the desired size for the scaled image. It is an integer value that determines the overall resolution of the output image. The default value is 1024, with a minimum of 64 and a maximum of 8192. This parameter is crucial as it guides the scaling process to ensure the image is resized to an optimal resolution.

multiple_of

This optional parameter defines the factor by which the width and height of the image should be divisible. It ensures that the scaled dimensions are aligned to a specific multiple, which can be important for certain applications that require images to have dimensions that are multiples of a specific number. The default value is 8, with a minimum of 1 and a maximum of 1024.

Width and height for scaling image to ideal resolution 🪴 Output Parameters:

width

The width output parameter provides the calculated width of the scaled image. It is an integer value that represents the new width of the image after scaling, ensuring that it is a multiple of the specified multiple_of parameter. This value is crucial for maintaining the aspect ratio and ensuring the image is scaled correctly.

height

The height output parameter provides the calculated height of the scaled image. Similar to the width, it is an integer value that represents the new height of the image after scaling, ensuring that it is a multiple of the specified multiple_of parameter. This value is essential for maintaining the aspect ratio and ensuring the image is scaled correctly.

Width and height for scaling image to ideal resolution 🪴 Usage Tips:

• Ensure that the target_size is set according to the desired resolution for your specific use case, balancing between image quality and processing efficiency.
• Use the multiple_of parameter to align the image dimensions to specific requirements, especially if the image will be used in applications that require dimensions to be multiples of a certain number.
• Consider the aspect ratio of the original image when setting the target_size to avoid distortion in the scaled image.

Width and height for scaling image to ideal resolution 🪴 Common Errors and Solutions:

Invalid target size

• Explanation: The target_size provided is outside the allowed range (64 to 8192).
• Solution: Ensure that the target_size is set within the valid range to avoid errors during the scaling process.

Non-divisible dimensions

• Explanation: The calculated dimensions are not divisible by the specified multiple_of value.
• Solution: Adjust the multiple_of parameter to a value that allows the dimensions to be divisible, or modify the target_size to achieve the desired divisibility.
