ComfyUI Node: GR Checkered Board

GR Checkered Board:

The GR Checkered Board node is designed to generate a checkered board pattern image, which can be used as a background, texture, or visual element in your AI art projects. This node allows you to customize various aspects of the checkered board, including the number of rows and columns, the size of each tile, and the colors of the tiles. Additionally, you can add borders around each tile and an outer border around the entire checkered board, with customizable colors for these borders. This flexibility makes the GR Checkered Board node a powerful tool for creating visually appealing and unique patterns that can enhance your artwork.

GR Checkered Board Input Parameters:

rows

This parameter specifies the number of rows in the checkered board. Increasing the number of rows will add more horizontal divisions to the pattern, making the tiles smaller if the overall size of the board remains constant. There is no strict minimum or maximum value, but typical values range from 2 to 100. The default value is usually set to 8.

columns

This parameter determines the number of columns in the checkered board. Similar to the rows parameter, increasing the number of columns will add more vertical divisions, resulting in smaller tiles. There is no strict minimum or maximum value, but typical values range from 2 to 100. The default value is usually set to 8.

tile_size

This parameter defines the size of each individual tile in the checkered board. The size is usually measured in pixels. Larger tile sizes will result in fewer tiles fitting within the same overall board size, while smaller tile sizes will increase the number of tiles. The default value is typically set to 50 pixels.

color1

This parameter sets the color of the first set of tiles in the checkered pattern. The color can be specified using standard color names (e.g., "red", "blue") or hexadecimal color codes (e.g., "#FF0000" for red). The default color is often set to white.

color2

This parameter sets the color of the second set of tiles in the checkered pattern. Similar to color1, the color can be specified using standard color names or hexadecimal color codes. The default color is often set to black.

border

This parameter specifies the width of the border around each individual tile. The width is usually measured in pixels. A border width of 0 means no border will be drawn. The default value is typically set to 0 pixels.

border_color

This parameter sets the color of the border around each individual tile. The color can be specified using standard color names or hexadecimal color codes. The default color is often set to black.

outer_border

This parameter defines the width of the outer border around the entire checkered board. The width is usually measured in pixels. A width of 0 means no outer border will be drawn. The default value is typically set to 0 pixels.

outer_border_color

This parameter sets the color of the outer border around the entire checkered board. The color can be specified using standard color names or hexadecimal color codes. The default color is often set to black.

GR Checkered Board Output Parameters:

checkered_board_image

This output parameter provides the generated checkered board image. The image can be used directly in your AI art projects or further processed using other nodes. The checkered board image will reflect all the customizations specified through the input parameters, including the number of rows and columns, tile size, colors, and borders.

GR Checkered Board Usage Tips:

• Experiment with different combinations of rows and columns to create various patterns and effects. For example, a higher number of rows and columns with smaller tile sizes can create a more intricate pattern.
• Use contrasting colors for color1 and color2 to make the checkered pattern stand out. For a more subtle effect, choose colors that are closer in shade.
• Adding a border around each tile can help to define the edges of the tiles more clearly, especially when using similar colors for color1 and color2.
• The outer_border can be useful for creating a framed effect around the checkered board, making it look more polished and complete.

GR Checkered Board Common Errors and Solutions:

"Invalid color value"

• Explanation: This error occurs when the color specified for color1, color2, border_color, or outer_border_color is not recognized.
• Solution: Ensure that you are using valid color names or hexadecimal color codes. For example, use "red" or "#FF0000" for red.

"Tile size too large"

• Explanation: This error occurs when the specified tile_size is too large to fit within the overall dimensions of the checkered board given the number of rows and columns.
• Solution: Reduce the tile_size or increase the number of rows and columns to ensure that the tiles fit within the board.

"Border width too large"

• Explanation: This error occurs when the specified border or outer_border width is too large relative to the tile size or overall board size.
• Solution: Reduce the border or outer_border width to ensure that the borders fit within the tiles and the overall board dimensions.
