ComfyUI Node: TileCalc (Legacy)

TileCalc (Legacy):

The TileCalc node is designed to calculate the final dimensions of an image after it has been divided into smaller tiles and then reassembled. This node is particularly useful for AI artists who work with large images and need to process them in smaller, more manageable sections. By calculating the final height and width of the reassembled image, TileCalc ensures that the tiles fit together seamlessly, taking into account any overlap between tiles. This helps in maintaining the integrity and continuity of the image, making it an essential tool for tasks that involve image tiling and stitching.

TileCalc (Legacy) Input Parameters:

tile_height

tile_height specifies the height of each individual tile in pixels. This parameter determines how tall each tile will be when the image is divided. The minimum value is 64 pixels, the maximum value is 4096 pixels, and the default value is 64 pixels. Adjusting this parameter affects the number of tiles generated and the final height of the reassembled image.

tile_width

tile_width specifies the width of each individual tile in pixels. This parameter determines how wide each tile will be when the image is divided. The minimum value is 64 pixels, the maximum value is 4096 pixels, and the default value is 64 pixels. Adjusting this parameter affects the number of tiles generated and the final width of the reassembled image.

overlap

overlap defines the number of pixels that each tile will overlap with its neighboring tiles. This parameter is crucial for ensuring that there are no gaps between tiles when they are reassembled. The minimum value is 0 pixels, the maximum value is 4096 pixels, and the default value is 64 pixels. Adjusting this parameter can help in achieving smoother transitions between tiles.

tile_width_n

tile_width_n specifies the number of tiles along the width of the image. This parameter determines how many tiles will be created horizontally. The minimum value is 1, the maximum value is 9, and the default value is 3. Adjusting this parameter affects the final width of the reassembled image.

tile_height_n

tile_height_n specifies the number of tiles along the height of the image. This parameter determines how many tiles will be created vertically. The minimum value is 1, the maximum value is 9, and the default value is 3. Adjusting this parameter affects the final height of the reassembled image.

TileCalc (Legacy) Output Parameters:

final_height

final_height represents the calculated height of the reassembled image after accounting for the specified tile height, number of tiles, and overlap. This output is crucial for understanding the dimensions of the final image and ensuring that all tiles fit together correctly.

final_width

final_width represents the calculated width of the reassembled image after accounting for the specified tile width, number of tiles, and overlap. This output is essential for understanding the dimensions of the final image and ensuring that all tiles fit together correctly.

TileCalc (Legacy) Usage Tips:

• To achieve a seamless reassembly of tiles, ensure that the overlap parameter is set appropriately based on the content of your image. Higher overlap values can help in blending the edges of tiles more smoothly.
• Experiment with different tile_height and tile_width values to find the optimal tile size for your specific image processing task. Smaller tiles may be easier to process but could increase the number of tiles and processing time.
• Use the tile_width_n and tile_height_n parameters to control the number of tiles generated. This can be useful for balancing between the number of tiles and the final image dimensions.

TileCalc (Legacy) Common Errors and Solutions:

"Invalid tile dimensions"

• Explanation: This error occurs when the specified tile_height or tile_width is outside the allowed range (64 to 4096 pixels).
• Solution: Ensure that both tile_height and tile_width are set within the valid range of 64 to 4096 pixels.

"Overlap value out of range"

• Explanation: This error occurs when the overlap parameter is set to a value outside the allowed range (0 to 4096 pixels).
• Solution: Adjust the overlap parameter to be within the valid range of 0 to 4096 pixels.

"Number of tiles out of range"

• Explanation: This error occurs when the tile_width_n or tile_height_n parameters are set to values outside the allowed range (1 to 9).
• Solution: Ensure that both tile_width_n and tile_height_n are set within the valid range of 1 to 9.
