ComfyUI Node: Empty Images

Empty Images:

The Empty Images node is designed to generate blank images with customizable dimensions, color, and batch size. This node is particularly useful for AI artists who need to create placeholder images or initialize image data for further processing. By allowing you to specify the width, height, and color of the images, this node provides flexibility in creating images that fit your specific needs. The ability to generate multiple images in a batch enhances efficiency, especially when working with large datasets or preparing images for batch processing. The node's primary function is to produce images filled with a single color, which can serve as a base for various artistic or computational applications.

Empty Images Input Parameters:

width

The width parameter specifies the width of the generated image in pixels. It determines how wide the image will be, allowing you to tailor the image size to your specific requirements. The minimum value is 1, the maximum value is determined by the system's maximum resolution capability, and the default value is 512 pixels.

height

The height parameter defines the height of the generated image in pixels. Similar to the width, it allows you to control the vertical size of the image. The minimum value is 1, the maximum value is determined by the system's maximum resolution capability, and the default value is 512 pixels.

batch_size

The batch_size parameter indicates the number of images to generate in a single batch. This is particularly useful when you need multiple images with the same specifications. The minimum value is 1, the maximum value is 4096, and the default value is 1.

color

The color parameter sets the color of the generated images. It is represented as an integer value corresponding to a color code, allowing you to fill the image with any color of your choice. The minimum value is 0 (black), the maximum value is 0xFFFFFF (white), and the default value is 0 (black).

Empty Images Output Parameters:

IMAGE

The output parameter IMAGE represents the generated image or batch of images. Each image is filled with the specified color and has the dimensions defined by the width and height parameters. This output can be used as a base for further image processing or as a placeholder in various applications.

Empty Images Usage Tips:

• To create a series of uniform images for testing or as placeholders, set the batch_size to the desired number of images and adjust the width and height to match your requirements.
• Use the color parameter to generate images with specific background colors, which can be useful for creating themed datasets or testing color-based algorithms.

Empty Images Common Errors and Solutions:

Non-matching input sizes got {len(batches)} Image Batches, {len(labels)} Labels for label type {l_type}

• Explanation: This error occurs when the number of image batches does not match the number of labels provided for a specific label type.
• Solution: Ensure that the number of labels matches the number of image batches, or provide a single label to be applied to all batches.

Invalid resolution value

• Explanation: This error is triggered when the specified width or height exceeds the system's maximum resolution capability.
• Solution: Adjust the width and height parameters to values within the allowed range, ensuring they do not exceed the maximum resolution.
