ComfyUI Node: ImageCompositeBy_Zho

ImageCompositeBy_Zho:

The ImageCompositeBy_Zho node is designed to facilitate the seamless combination of two images into a single composite image. This node allows you to specify the positioning of each image within a container, adjust their transparency levels, and choose the background image for the composite. The primary goal of this node is to provide a flexible and intuitive way to overlay images, making it an essential tool for AI artists looking to create complex visual compositions. By leveraging different methods such as "pair" or "matrix," you can achieve various compositional effects, enhancing your creative workflow.

ImageCompositeBy_Zho Input Parameters:

images_a

This parameter represents the first image to be used in the composite. It is essential for defining the primary visual element of your composition. The image should be provided in a compatible format.

images_b

This parameter represents the second image to be used in the composite. It serves as the secondary visual element that will be overlaid or combined with the first image.

images_a_x

This parameter specifies the horizontal position of the first image within the container. It is a float value ranging from 0.0 to 1.0, where 0.0 represents the leftmost position and 1.0 represents the rightmost position. The default value is 0.0.

images_a_y

This parameter specifies the vertical position of the first image within the container. It is a float value ranging from 0.0 to 1.0, where 0.0 represents the topmost position and 1.0 represents the bottommost position. The default value is 0.0.

images_b_x

This parameter specifies the horizontal position of the second image within the container. It is a float value ranging from 0.0 to 1.0, where 0.0 represents the leftmost position and 1.0 represents the rightmost position. The default value is 0.0.

images_b_y

This parameter specifies the vertical position of the second image within the container. It is a float value ranging from 0.0 to 1.0, where 0.0 represents the topmost position and 1.0 represents the bottommost position. The default value is 0.0.

alpha_a

This parameter controls the transparency level of the first image. It is a float value ranging from 0.0 (completely transparent) to 1.0 (completely opaque). The default value is 1.0.

alpha_b

This parameter controls the transparency level of the second image. It is a float value ranging from 0.0 (completely transparent) to 1.0 (completely opaque). The default value is 1.0.

background

This parameter determines which image will be used as the background in the composite. It can be either "images_a" or "images_b".

method

This parameter specifies the compositing method to be used. It can be either "pair" or "matrix", allowing for different styles of image combination.

ImageCompositeBy_Zho Output Parameters:

IMAGE

The output is a single composite image that combines the two input images based on the specified parameters. This image reflects the positioning, transparency, and background choices made, providing a final visual result ready for further use or display.

ImageCompositeBy_Zho Usage Tips:

• To achieve a balanced overlay, experiment with the alpha_a and alpha_b parameters to adjust the transparency levels of each image.
• Use the images_a_x, images_a_y, images_b_x, and images_b_y parameters to fine-tune the positioning of each image within the container, ensuring they align as desired.
• Select the appropriate background parameter to determine which image should serve as the base layer, affecting the overall look of the composite.

ImageCompositeBy_Zho Common Errors and Solutions:

ValueError: "Container can't be smaller than max width or height of images."

• Explanation: This error occurs when the container size is smaller than the maximum width or height of the input images.
• Solution: Ensure that the container dimensions are large enough to accommodate the largest input image. Adjust the container size or resize the input images accordingly.

TypeError: "Invalid input type for images_a or images_b."

• Explanation: This error occurs when the input images are not provided in a compatible format.
• Solution: Verify that the input images are in the correct format and try again. Ensure that the images are properly loaded and passed to the node.

ValueError: "Invalid value for alpha_a or alpha_b."

• Explanation: This error occurs when the transparency values are outside the acceptable range of 0.0 to 1.0.
• Solution: Adjust the alpha_a and alpha_b parameters to be within the range of 0.0 to 1.0. Use the default values if unsure.
