ComfyUI Node: Merge Image Tile

Merge Image Tile:

The ETN_MergeImageTile node is designed to seamlessly integrate a smaller image tile into a larger image canvas based on a specified layout and index. This node is particularly useful for tasks that involve working with subdivided images, such as image processing, editing, or AI-based image generation. By allowing you to merge individual tiles back into the main image, it ensures that the final output maintains a cohesive and unified appearance. The primary function of this node is to take a tile and place it at the correct position within the larger image, blending it smoothly to avoid visible seams or artifacts.

Merge Image Tile Input Parameters:

image

This parameter represents the main image canvas into which the tile will be merged. It is of type IMAGE and serves as the base image that will be updated with the new tile. The image should be a tensor that can accommodate the tile at the specified index.

layout

The layout parameter defines the tiling structure of the main image. It is of type TILE_LAYOUT and provides the necessary information about how the image is divided into tiles, including the size and position of each tile. This layout ensures that the tile is placed correctly within the main image.

index

The index parameter specifies the position within the layout where the tile should be merged. It is of type INT with a minimum value of 0. This index must be within the range of the total number of tiles defined by the layout. It determines the exact location in the main image where the tile will be inserted.

tile

This parameter represents the smaller image tile that will be merged into the main image. It is of type IMAGE and should match the dimensions expected by the layout at the specified index. The tile is blended into the main image to ensure a smooth transition.

Merge Image Tile Output Parameters:

image

The output parameter is the updated main image with the tile merged into it. It is of type IMAGE and reflects the main image after the specified tile has been integrated at the correct position. This ensures that the final image maintains a cohesive and unified appearance.

Merge Image Tile Usage Tips:

• Ensure that the index parameter is within the valid range of the layout to avoid errors.
• Use a consistent TILE_LAYOUT to maintain uniformity in the final image.
• Verify that the dimensions of the tile match the expected size for the specified index in the layout to ensure proper blending.

Merge Image Tile Common Errors and Solutions:

Index {index} out of range

• Explanation: This error occurs when the specified index is outside the valid range defined by the layout.
• Solution: Ensure that the index is within the range of the total number of tiles in the layout.

Image size must be divisible by 8

• Explanation: This error occurs if the dimensions of the main image are not divisible by 8. - Solution: Adjust the dimensions of the main image to be divisible by 8 to meet the node's requirements.

Tile size must be divisible by 8

• Explanation: This error occurs if the dimensions of the tile are not divisible by 8.
• Solution: Adjust the dimensions of the tile to be divisible by 8 to ensure proper merging.
