ComfyUI Node: Empty RGB image

Empty RGB image:

The Empty RGB image node is designed to generate a blank RGB image with specified dimensions and color. This node is particularly useful for creating placeholder images or initializing image data for further processing. By allowing you to define the width, height, batch size, and color of the image, it provides flexibility in generating images that meet your specific requirements. The primary goal of this node is to offer a straightforward way to create uniform images that can be used in various image processing and AI art tasks.

Empty RGB image Input Parameters:

width

The width parameter specifies the width of the generated image in pixels. It accepts integer values with a default of 512, a minimum of 1, and a maximum defined by the system's maximum resolution. Adjusting this parameter changes the horizontal size of the image.

height

The height parameter defines the height of the generated image in pixels. Similar to the width parameter, it accepts integer values with a default of 512, a minimum of 1, and a maximum defined by the system's maximum resolution. Modifying this parameter alters the vertical size of the image.

batch_size

The batch_size parameter determines the number of images to generate in a single batch. It accepts integer values with a default of 1, a minimum of 1, and a maximum of 4096. This parameter is useful for generating multiple images simultaneously, which can be beneficial for batch processing tasks.

color

The color parameter sets the color of the generated image using an integer value representing the RGB color code. It accepts values ranging from 0 to 0xFFFFFF, with a default of 0 (black). This parameter allows you to specify the exact color of the image, making it versatile for different use cases.

Empty RGB image Output Parameters:

IMAGE

The output of this node is an IMAGE, which is a tensor representing the generated RGB image. The image tensor contains the pixel data for the specified width, height, batch size, and color. This output can be used as input for further image processing or AI art generation tasks.

Empty RGB image Usage Tips:

• To create a solid color background for your artwork, set the width and height to match your canvas size and choose a color that complements your design.
• Use the batch_size parameter to generate multiple images at once, which can save time when you need several placeholders or uniform images for batch processing.

Empty RGB image Common Errors and Solutions:

"Invalid width or height value"

• Explanation: This error occurs when the width or height parameter is set to a value outside the allowed range.
• Solution: Ensure that the width and height values are within the specified range (minimum 1, maximum defined by the system's maximum resolution).

"Batch size exceeds maximum limit"

• Explanation: This error happens when the batch_size parameter is set to a value greater than 4096. - Solution: Adjust the batch_size parameter to a value within the allowed range (minimum 1, maximum 4096).

"Invalid color value"

• Explanation: This error is triggered when the color parameter is set to a value outside the range of 0 to 0xFFFFFF.
• Solution: Make sure the color value is within the valid range for RGB color codes (0 to 0xFFFFFF).
