ComfyUI Node: TileMerge (Legacy)

TileMerge (Legacy):

TileMerge is a node designed to seamlessly combine multiple image tiles into a single cohesive image. This node is particularly useful when working with large images that have been split into smaller tiles for processing or manipulation. By merging these tiles back together, TileMerge ensures that the final image retains its original dimensions and quality. This node is essential for workflows that involve tiling operations, as it simplifies the process of reassembling the image, saving you time and effort. The primary goal of TileMerge is to provide a straightforward and efficient method for recombining image tiles, making it an invaluable tool for AI artists working with high-resolution images or complex compositions.

TileMerge (Legacy) Input Parameters:

tile_height

This parameter specifies the height of each individual tile in pixels. It is crucial for determining how the tiles will be merged back together. The minimum value is 64, the maximum value is 4096, and the default value is 64. Adjusting this parameter affects the vertical alignment of the tiles in the final image.

tile_width

This parameter defines the width of each individual tile in pixels. Similar to tile_height, it plays a significant role in the horizontal alignment of the tiles during the merging process. The minimum value is 64, the maximum value is 4096, and the default value is 64. Properly setting this parameter ensures that the tiles fit together correctly.

overlap

This parameter indicates the number of pixels that overlap between adjacent tiles. Overlap is important for blending the edges of the tiles to create a seamless final image. The minimum value is 0, the maximum value is 4096, and the default value is 64. Adjusting the overlap can help reduce visible seams between tiles.

tile_width_n

This parameter determines the number of tiles along the width of the final image. It helps in calculating the total width of the merged image. The minimum value is 1, the maximum value is 9, and the default value is 3. Setting this parameter correctly ensures that all tiles are included in the final image.

tile_height_n

This parameter specifies the number of tiles along the height of the final image. It is used to calculate the total height of the merged image. The minimum value is 1, the maximum value is 9, and the default value is 3. Properly configuring this parameter ensures that the final image includes all the tiles.

TileMerge (Legacy) Output Parameters:

final_height

This output parameter represents the total height of the merged image in pixels. It is calculated based on the tile_height, overlap, and tile_height_n parameters. The final_height ensures that the merged image has the correct vertical dimensions.

final_width

This output parameter indicates the total width of the merged image in pixels. It is derived from the tile_width, overlap, and tile_width_n parameters. The final_width ensures that the merged image has the correct horizontal dimensions.

TileMerge (Legacy) Usage Tips:

• Ensure that the tile_height and tile_width parameters match the dimensions of the tiles you are merging to avoid misalignment.
• Adjust the overlap parameter to blend the edges of the tiles smoothly, reducing visible seams in the final image.
• Verify the tile_width_n and tile_height_n parameters to include all tiles in the final image, ensuring no tiles are left out.

TileMerge (Legacy) Common Errors and Solutions:

Mismatched Tile Dimensions

• Explanation: The dimensions of the tiles do not match the specified tile_height and tile_width parameters.
• Solution: Double-check the dimensions of your tiles and ensure they match the tile_height and tile_width parameters.

Incorrect Overlap Value

• Explanation: The overlap parameter is set too high or too low, causing visible seams or excessive blending.
• Solution: Adjust the overlap parameter to find a balance that minimizes seams without excessive blending.

Missing Tiles in Final Image

• Explanation: The tile_width_n or tile_height_n parameters are set incorrectly, resulting in missing tiles.
• Solution: Verify and adjust the tile_width_n and tile_height_n parameters to include all tiles in the final image.
