ComfyUI Node: Image Blank

Image Blank:

The Image Blank node is designed to generate a blank image of specified dimensions and color. This node is particularly useful when you need a solid color background or a placeholder image for further processing or compositing in your AI art projects. By allowing you to define the width, height, and RGB color values, it provides flexibility in creating images that meet your specific requirements. The main goal of this node is to offer a simple yet powerful way to create blank canvases that can be used as a starting point for various artistic endeavors.

Image Blank Input Parameters:

width

The width parameter specifies the width of the blank image in pixels. It accepts integer values with a default of 512, a minimum of 8, and a maximum of 4096. Adjusting this parameter will change the horizontal size of the generated image.

height

The height parameter specifies the height of the blank image in pixels. It accepts integer values with a default of 512, a minimum of 8, and a maximum of 4096. Adjusting this parameter will change the vertical size of the generated image.

red

The red parameter defines the red component of the RGB color for the blank image. It accepts integer values ranging from 0 to 255, with a default value of 255. This parameter controls the intensity of the red color in the image.

green

The green parameter defines the green component of the RGB color for the blank image. It accepts integer values ranging from 0 to 255, with a default value of 255. This parameter controls the intensity of the green color in the image.

blue

The blue parameter defines the blue component of the RGB color for the blank image. It accepts integer values ranging from 0 to 255, with a default value of 255. This parameter controls the intensity of the blue color in the image.

Image Blank Output Parameters:

IMAGE

The output parameter is an image tensor representing the blank image generated based on the specified width, height, and RGB color values. This image can be used as a base layer for further image processing or as a background in your AI art projects.

Image Blank Usage Tips:

• To create a solid color background for your artwork, set the width and height to match your canvas size and adjust the RGB values to your desired color.
• Use this node to generate placeholder images when you need a specific size and color for testing or layout purposes.
• Combine this node with other image processing nodes to create complex compositions or effects.

Image Blank Common Errors and Solutions:

"Width and height must be multiples of 8"

• Explanation: The width and height values must be multiples of 8 to ensure proper image processing.
• Solution: Adjust the width and height values to be multiples of 8. For example, if you need a 500x500 image, change the dimensions to 504x504.

"Invalid RGB value"

• Explanation: The RGB values must be within the range of 0 to 255.
• Solution: Ensure that the red, green, and blue parameters are set to values between 0 and 255. Adjust any values that fall outside this range.
