📉 CR XY Index Description

Converts single index to x and y coordinates in grid for efficient data handling in multi-dimensional arrays or grids.

📉 CR XY Index:

The CR XY Index node is designed to help you navigate and manage a grid-based system by converting a single index value into its corresponding x and y coordinates within the grid. This node is particularly useful for tasks that involve working with multi-dimensional arrays or grids, such as image processing or data visualization. By providing an easy way to map a linear index to a two-dimensional grid, the CR XY Index node simplifies the process of accessing and manipulating grid elements. This can be especially beneficial when dealing with large datasets or complex grid structures, as it allows for more intuitive and efficient data handling.

📉 CR XY Index Input Parameters:

x_columns

This parameter specifies the number of columns in the grid. It determines the width of the grid and affects how the linear index is mapped to the x-coordinate. The default value is 5, with a minimum of 0 and a maximum of 9999. Adjusting this value will change the horizontal span of the grid, which can be useful for different grid configurations.

y_rows

This parameter defines the number of rows in the grid. It determines the height of the grid and affects how the linear index is mapped to the y-coordinate. The default value is 5, with a minimum of 0 and a maximum of 9999. Modifying this value will change the vertical span of the grid, allowing for various grid sizes.

index

This parameter represents the linear index that you want to convert into x and y coordinates. The index value starts from 1 and is adjusted internally by subtracting 1 to align with zero-based indexing. The default value is 0, with a minimum of 0 and a maximum of 9999. This parameter is crucial for determining the specific grid element you want to access.

📉 CR XY Index Output Parameters:

x

This output parameter provides the x-coordinate corresponding to the given index within the grid. It is calculated based on the number of columns specified and helps you identify the horizontal position of the grid element.

y

This output parameter provides the y-coordinate corresponding to the given index within the grid. It is derived from the number of columns and the index value, helping you determine the vertical position of the grid element.

show_help

This output parameter returns a URL to the documentation page for the CR XY Index node. It is a helpful resource for understanding the node's functionality and usage in more detail. The URL is: https://github.com/Suzie1/ComfyUI_Comfyroll_CustomNodes/wiki/XY-Grid-Nodes#cr-xy-index.

📉 CR XY Index Usage Tips:

  • Ensure that the x_columns and y_rows parameters are set according to the dimensions of your grid to accurately map the index to the correct coordinates.
  • Use the index parameter to specify the grid element you want to access, keeping in mind that the index starts from 1. - Refer to the show_help URL for additional guidance and examples on how to use the CR XY Index node effectively.

📉 CR XY Index Common Errors and Solutions:

Index out of range

  • Explanation: The provided index value exceeds the total number of elements in the grid.
  • Solution: Ensure that the index value is within the range of the total number of grid elements, calculated as x_columns * y_rows.

Invalid grid dimensions

  • Explanation: The x_columns or y_rows parameters are set to invalid values (e.g., negative numbers).
  • Solution: Verify that both x_columns and y_rows are set to valid, positive integers within the specified range.

Incorrect index mapping

  • Explanation: The index value does not correctly map to the intended grid coordinates.
  • Solution: Double-check the values of x_columns, y_rows, and index to ensure they are set correctly and align with your grid structure.
