ComfyUI Node: Image Blending Mode

Image Blending Mode:

The Image Blending Mode node is designed to combine two images using various blending techniques, allowing you to create visually appealing and complex compositions. This node provides a range of blending modes such as add, multiply, overlay, screen, and more, each offering a unique way to merge images. By adjusting the blend percentage, you can control the intensity of the blending effect, making it a versatile tool for AI artists looking to enhance their digital artwork. The primary goal of this node is to offer a flexible and intuitive way to blend images, enabling you to achieve the desired artistic effect with ease.

Image Blending Mode Input Parameters:

image_a

This parameter represents the first image to be blended. It serves as one of the base images in the blending process. The image should be in a compatible format that the node can process.

image_b

This parameter represents the second image to be blended. It acts as the other base image in the blending process. Like image_a, this image should also be in a compatible format.

blend_percentage

This parameter controls the intensity of the blending effect between the two images. It is a float value ranging from 0.0 to 1.0, where 0.0 means no blending (only image_a is visible) and 1.0 means full blending (only image_b is visible). The default value is 0.5, providing an equal blend of both images.

Image Blending Mode Output Parameters:

image

This output parameter represents the final blended image. The resulting image is a combination of image_a and image_b based on the selected blending mode and blend percentage. This output can be used for further processing or as a final artwork.

Image Blending Mode Usage Tips:

• Experiment with different blending modes to achieve various artistic effects. For example, the overlay mode can enhance contrast, while the screen mode can lighten the image.
• Adjust the blend percentage to fine-tune the blending effect. A lower percentage will make the effect more subtle, while a higher percentage will make it more pronounced.
• Use high-resolution images for better quality results, especially when blending images with intricate details.

Image Blending Mode Common Errors and Solutions:

Unsupported blend mode: <mode>

• Explanation: This error occurs when an invalid or unsupported blending mode is specified.
• Solution: Ensure that you are using one of the supported blending modes such as add, multiply, overlay, screen, etc. Refer to the node documentation for the complete list of supported modes.

Image size mismatch

• Explanation: This error occurs when the input images image_a and image_b have different dimensions.
• Solution: Make sure both images have the same dimensions before blending. You can resize the images to match their dimensions using an image editing tool or a preprocessing node.

Invalid blend percentage

• Explanation: This error occurs when the blend percentage is set outside the valid range of 0.0 to 1.0.
• Solution: Adjust the blend percentage to be within the valid range. The value should be between 0.0 and 1.0, inclusive.
