ComfyUI Node: Create Gradient From Coords

Create Gradient From Coords:

CreateGradientFromCoords is a powerful node designed to generate gradient images based on specified coordinates. This node allows you to create smooth transitions between colors across an image, which can be particularly useful for backgrounds, overlays, or artistic effects. By defining the start and end points of the gradient, as well as the colors and other parameters, you can achieve a wide range of visual effects. The node calculates the gradient direction and blends the colors accordingly, providing a high degree of control over the final image. This makes it an essential tool for AI artists looking to add dynamic and visually appealing elements to their creations.

Create Gradient From Coords Input Parameters:

coordinates

The coordinates parameter is a string that specifies the start and end points of the gradient. It should be formatted as a JSON string with two coordinate objects, each containing x and y values. This parameter is crucial as it determines the direction and length of the gradient. The input must be provided, and it is forced to be an input.

frame_width

The frame_width parameter defines the width of the generated image in pixels. It accepts integer values ranging from 16 to 4096, with a default value of 512. Adjusting this parameter will change the width of the gradient image, allowing you to fit it to different canvas sizes.

frame_height

The frame_height parameter specifies the height of the generated image in pixels. Similar to frame_width, it accepts integer values between 16 and 4096, with a default value of 512. This parameter allows you to control the height of the gradient image to match your design requirements.

start_color

The start_color parameter sets the initial color of the gradient. It accepts a string representing the color, with a default value of 'white'. This color will be used at the starting coordinate of the gradient, blending towards the end_color.

end_color

The end_color parameter defines the final color of the gradient. It accepts a string representing the color, with a default value of 'black'. This color will be used at the ending coordinate of the gradient, blending from the start_color.

multiplier

The multiplier parameter is a float that adjusts the intensity of the gradient. It accepts values ranging from 0.01 to 100.0, with a default value of 1.0. This parameter allows you to fine-tune the gradient's transition, making it more or less pronounced.

Create Gradient From Coords Output Parameters:

image

The image output parameter is the resulting gradient image generated by the node. This image is created based on the specified coordinates, colors, and other parameters. It can be used directly in your projects or further processed to achieve the desired visual effects.

Create Gradient From Coords Usage Tips:

• To create a smooth horizontal gradient, set the coordinates parameter with start and end points that have the same y value but different x values.
• Experiment with different start_color and end_color values to achieve unique color transitions that enhance your artwork.
• Use the multiplier parameter to adjust the gradient's intensity, making it more subtle or more dramatic depending on your needs.

Create Gradient From Coords Common Errors and Solutions:

Invalid JSON format in coordinates

• Explanation: The coordinates parameter must be a valid JSON string with two coordinate objects.
• Solution: Ensure that the coordinates string is correctly formatted as JSON, with proper use of double quotes and valid x and y values.

Frame width or height out of range

• Explanation: The frame_width and frame_height parameters must be within the specified range of 16 to 4096. - Solution: Adjust the frame_width and frame_height values to be within the acceptable range.

Invalid color format

• Explanation: The start_color and end_color parameters must be valid color strings.
• Solution: Use standard color names or hexadecimal color codes for the start_color and end_color parameters.
