ComfyUI Node: Scaled paste v4.7.3

Scaled paste v4.7.3:

The tri3d-scaled-paste node is designed to seamlessly integrate a foreground image onto a background image, with the ability to scale and position the foreground image precisely. This node is particularly useful for AI artists looking to create composite images where the foreground needs to be adjusted in size and position relative to the background. By utilizing a mask, the node ensures that only the desired parts of the foreground are blended into the background, allowing for smooth transitions and realistic compositions. The node's scaling and positioning capabilities are controlled through parameters that adjust the size and height of the foreground, making it a versatile tool for various artistic applications.

Scaled paste v4.7.3 Input Parameters:

image_background

This parameter represents the background image onto which the foreground image will be pasted. It is crucial as it serves as the canvas for the composite image. The dimensions of this image influence the scaling and positioning of the foreground image.

image_foreground

This parameter is the image that will be placed over the background. Its size and content are adjusted based on the scale_factor and height_factor to fit seamlessly onto the background image.

mask_foreground

The mask_foreground is a grayscale image that determines which parts of the foreground image are visible and which are transparent. This mask is essential for blending the foreground image into the background, ensuring that only the desired areas are visible.

scale_factor

The scale_factor controls the overall scaling of the foreground image. It affects how much the foreground image is enlarged or reduced before being pasted onto the background. A higher scale factor results in a larger foreground image.

height_factor

The height_factor adjusts the vertical positioning of the foreground image relative to the background. It influences the height at which the foreground image is placed, allowing for precise control over its vertical alignment.

Scaled paste v4.7.3 Output Parameters:

image_output

The image_output is the final composite image resulting from the scaled and positioned foreground image being pasted onto the background. This output is a seamless blend of the two images, with the foreground image adjusted according to the specified parameters.

Scaled paste v4.7.3 Usage Tips:

• To achieve a natural blend, ensure that the mask_foreground accurately represents the areas of the foreground image you want to be visible. A well-defined mask will result in a more realistic composite image.
• Experiment with different scale_factor and height_factor values to find the perfect balance for your composition. Small adjustments can significantly impact the final image's appearance.

Scaled paste v4.7.3 Common Errors and Solutions:

Image dimension mismatch

• Explanation: This error occurs when the dimensions of the background and foreground images are incompatible for the specified scaling and positioning.
• Solution: Ensure that the images are of compatible sizes or adjust the scale_factor and height_factor to accommodate the differences.

Mask application failure

• Explanation: This error happens when the mask_foreground is not correctly applied, leading to improper blending of the foreground image.
• Solution: Verify that the mask is a grayscale image and correctly aligned with the foreground image. Adjust the mask to ensure it accurately represents the desired visible areas.
