ComfyUI Node: Bounded Image Blend

Bounded Image Blend:

The Bounded Image Blend node is designed to seamlessly blend two images within specified boundaries, allowing for precise control over the blending process. This node is particularly useful for AI artists who want to combine elements from different images while maintaining a natural and cohesive look. By defining target boundaries and applying a blend factor, you can achieve smooth transitions between images, enhancing the overall visual appeal. The node also supports feathering, which softens the edges of the blended area, further improving the integration of the images. This functionality is essential for creating complex compositions and achieving professional-quality results in your artwork.

Bounded Image Blend Input Parameters:

target

The target parameter specifies the primary image that will serve as the base for the blending operation. This image will be blended with the source image within the defined boundaries. The quality and resolution of the target image can significantly impact the final result, so it is advisable to use high-quality images for best outcomes.

target_bounds

The target_bounds parameter defines the specific area within the target image where the blending will occur. This allows you to control precisely which part of the target image will be affected by the blend. The boundaries are typically defined by coordinates or a mask, ensuring that only the desired region is blended with the source image.

source

The source parameter specifies the secondary image that will be blended into the target image. This image will be integrated into the target image within the defined boundaries. Like the target image, the quality and resolution of the source image are crucial for achieving a seamless blend.

blend_factor

The blend_factor parameter controls the intensity of the blending between the target and source images. It is a float value ranging from 0.0 to 1.0, where 0.0 means no blending (only the target image is visible) and 1.0 means full blending (only the source image is visible). The default value is 0.5, providing an equal mix of both images. Adjusting this parameter allows you to fine-tune the blend to achieve the desired visual effect.

feathering

The feathering parameter softens the edges of the blended area, creating a smooth transition between the target and source images. This helps to avoid harsh lines and makes the blend appear more natural. Feathering is particularly useful when blending images with different textures or colors, as it helps to integrate them more seamlessly.

Bounded Image Blend Output Parameters:

image

The image parameter is the output of the Bounded Image Blend node. It is the final blended image that combines the target and source images within the specified boundaries. The output image retains the dimensions and resolution of the target image, with the blended area reflecting the specified blend factor and feathering settings. This output can be used directly in your artwork or further processed with other nodes to achieve the desired artistic effect.

Bounded Image Blend Usage Tips:

• Use high-resolution images for both the target and source to ensure a high-quality blend.
• Experiment with different blend_factor values to achieve the perfect balance between the target and source images.
• Utilize the feathering parameter to soften the edges of the blended area, especially when working with images that have different textures or colors.
• Define precise target_bounds to control exactly where the blending occurs, allowing for more detailed and intentional compositions.

Bounded Image Blend Common Errors and Solutions:

"Invalid image format"

• Explanation: This error occurs when the input images are not in a supported format.
• Solution: Ensure that both the target and source images are in a compatible format, such as JPEG or PNG.

"Target bounds out of range"

• Explanation: This error occurs when the specified target_bounds exceed the dimensions of the target image.
• Solution: Verify that the target_bounds are within the dimensions of the target image and adjust them if necessary.

"Blend factor out of range"

• Explanation: This error occurs when the blend_factor is set outside the valid range of 0.0 to 1.0.
• Solution: Ensure that the blend_factor is a float value between 0.0 and 1.0.

"Feathering value invalid"

• Explanation: This error occurs when the feathering parameter is set to an invalid value.
• Solution: Check that the feathering value is appropriate and within any specified limits for the node.
