ComfyUI Node: Blend Images

Blend Images:

The JDC_BlendImages node is designed to seamlessly blend two images together, creating a smooth transition between them. This node is particularly useful for AI artists looking to combine different visual elements into a cohesive image. By adjusting the blend factor, you can control the degree to which each image contributes to the final result, allowing for creative and nuanced compositions. The node ensures that the images are properly aligned and resized if necessary, making the blending process straightforward and efficient.

Blend Images Input Parameters:

IMAGE_A

This parameter represents the first image to be blended. It serves as one of the two primary sources for the blending operation. The image should be provided in a compatible format that the node can process.

IMAGE_B

This parameter represents the second image to be blended. Like IMAGE_A, it is a primary source for the blending operation. The node will handle any necessary resizing to ensure that IMAGE_B matches the dimensions of IMAGE_A.

blend

The blend parameter is a floating-point value that determines the blending ratio between IMAGE_A and IMAGE_B. A value of 0.0 means that only IMAGE_A will be visible, while a value of 1.0 means that only IMAGE_B will be visible. Values between 0.0 and 1.0 will result in a mix of both images. The default value is 0.5, with a minimum of 0 and a maximum of 1, allowing for fine-tuned control over the blending process.

Blend Images Output Parameters:

IMAGE

The output parameter is the resulting image from the blending operation. This image is a combination of IMAGE_A and IMAGE_B, blended according to the specified blend factor. The output image retains the dimensions of IMAGE_A and is provided in a format suitable for further processing or final use.

Blend Images Usage Tips:

• Experiment with different blend values to achieve the desired level of transparency and merging between the two images.
• Ensure that the images you are blending have similar content or themes for a more harmonious result.
• Use this node to create double exposure effects or to overlay textures and patterns onto base images.

Blend Images Common Errors and Solutions:

Unsupported image format

• Explanation: The provided images are in a format that the node cannot process.
• Solution: Convert the images to a supported format, such as JPEG or PNG, before using the node.

Mismatched image dimensions

• Explanation: The dimensions of IMAGE_A and IMAGE_B do not match, causing issues during the blending process.
• Solution: The node automatically resizes IMAGE_B to match IMAGE_A. Ensure that the content of the images aligns well after resizing.

Invalid blend value

• Explanation: The blend parameter is set to a value outside the allowed range (0 to 1).
• Solution: Adjust the blend value to be within the range of 0 to 1. The default value is 0.5, which provides an equal mix of both images.
