ComfyUI Node: Runware Image Upscaler

Runware Image Upscaler:

The Runware Image Upscaler is a powerful tool designed to enhance the resolution and quality of your images using advanced upscaling techniques. This node is particularly beneficial for transforming low-resolution images into sharp, high-definition visuals, making it an essential asset for AI artists looking to improve the clarity and detail of their digital artwork. By leveraging Runware's sophisticated upscaling API, this node allows you to increase the size of your images while maintaining or even enhancing their visual quality. Whether you're working with digital art, photography, or any other form of visual media, the Runware Image Upscaler provides a seamless way to achieve high-quality results without the need for extensive technical knowledge.

Runware Image Upscaler Input Parameters:

Image

This parameter specifies the input image that you wish to upscale. It is the starting point for the upscaling process, and the quality of the input image can influence the final output. The image should be provided in a format compatible with the node's processing capabilities.

upscaleFactor

The upscaleFactor determines the level of upscaling applied to the input image. Each level increases the size of the image by the corresponding factor, allowing you to choose between doubling, tripling, or quadrupling the image size. The default value is 2, with a minimum of 2 and a maximum of 4. Selecting a higher factor will result in a larger image, but it may also require more processing power and time.

outputFormat

This parameter defines the format of the output image. The default format is "WEBP," which is known for its efficient compression and quality retention. You can choose other formats as specified in the Runware output formats, depending on your needs for compatibility and quality.

Runware Image Upscaler Output Parameters:

IMAGE

The output of the Runware Image Upscaler is the upscaled image itself. This image is returned in the format specified by the outputFormat parameter and is enhanced in resolution and quality compared to the original input. The upscaled image can be used directly in your projects, providing a higher level of detail and clarity.

Runware Image Upscaler Usage Tips:

• To achieve the best results, start with the highest quality input image available, as this will provide more data for the upscaling process to work with.
• Experiment with different upscaleFactor values to find the right balance between image size and processing time, especially if working with limited computational resources.
• Consider the final use case of the image when selecting the outputFormat, as different formats may offer varying levels of quality and compatibility.

Runware Image Upscaler Common Errors and Solutions:

"Mask Image Requires Seed Image To Be Provided!"

• Explanation: This error occurs when a mask image is provided without a corresponding seed image, which is necessary for the masking process.
• Solution: Ensure that you provide a seed image whenever you include a mask image in your configuration. The seed image acts as a base for the mask to be applied correctly.

"OOM_EXCEPTION"

• Explanation: This error indicates that the system has run out of memory while attempting to upscale the image, often due to a high upscaleFactor or large input image size.
• Solution: Try reducing the upscaleFactor or using a smaller input image. Additionally, ensure that your system has sufficient memory resources available for the upscaling process.
