ComfyUI Node: ImageComposite_Zho

ImageComposite_Zho:

The ImageComposite_Zho node is designed to facilitate the seamless combination of two images into a single composite image. This node allows you to position and blend two images (images_a and images_b) within a specified container, providing control over their transparency and placement. The primary goal of this node is to enable the creation of complex image compositions with ease, making it a valuable tool for AI artists looking to merge visual elements creatively. By adjusting parameters such as the position, transparency, and background, you can achieve a wide range of visual effects, from simple overlays to intricate image matrices.

ImageComposite_Zho Input Parameters:

images_a

This parameter represents the first image to be used in the composite. It is an essential input and must be provided for the node to function.

images_b

This parameter represents the second image to be used in the composite. Like images_a, it is a required input.

alpha_a

This parameter controls the transparency of images_a. It accepts a float value ranging from 0.0 (completely transparent) to 1.0 (completely opaque), with a default value of 1.0. Adjusting this parameter allows you to blend images_a with the background and images_b.

alpha_b

This parameter controls the transparency of images_b. It accepts a float value ranging from 0.0 to 1.0, with a default value of 1.0. This parameter helps in blending images_b with the background and images_a.

images_a_x

This parameter specifies the horizontal position of images_a within the container. It accepts a float value between 0.0 and 1.0, with a default value of 0.0. The value represents the percentage offset from the left edge of the container.

images_a_y

This parameter specifies the vertical position of images_a within the container. It accepts a float value between 0.0 and 1.0, with a default value of 0.0. The value represents the percentage offset from the top edge of the container.

images_b_x

This parameter specifies the horizontal position of images_b within the container. It accepts a float value between 0.0 and 1.0, with a default value of 0.0. The value represents the percentage offset from the left edge of the container.

images_b_y

This parameter specifies the vertical position of images_b within the container. It accepts a float value between 0.0 and 1.0, with a default value of 0.0. The value represents the percentage offset from the top edge of the container.

background

This parameter determines which image (images_a or images_b) will serve as the background for the composite. It accepts either images_a or images_b.

method

This parameter defines the method of compositing the images. It accepts either pair or matrix, allowing you to choose between a simple overlay or a more complex matrix arrangement.

ImageComposite_Zho Output Parameters:

IMAGE

The output of the ImageComposite_Zho node is a single composite image that combines images_a and images_b based on the specified parameters. This composite image reflects the positioning, transparency, and background settings applied, resulting in a unified visual output.

ImageComposite_Zho Usage Tips:

• To create a simple overlay effect, set method to pair and adjust the alpha_a and alpha_b parameters to blend the images smoothly.
• For more complex compositions, use the matrix method and experiment with different images_a_x, images_a_y, images_b_x, and images_b_y values to achieve the desired layout.
• Utilize the background parameter to determine which image should serve as the base layer, providing a foundation for the composite.

ImageComposite_Zho Common Errors and Solutions:

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.

Invalid value for alpha_a or alpha_b.

• Explanation: This error occurs when the transparency values for alpha_a or alpha_b are outside the acceptable range (0.0 to 1.0).
• Solution: Verify that the alpha_a and alpha_b parameters are set within the range of 0.0 to 1.0. Adjust the values to fall within this range.

Invalid method specified.

• Explanation: This error occurs when an unsupported method is specified for the method parameter.
• Solution: Ensure that the method parameter is set to either pair or matrix. Double-check the spelling and case of the method value.
