ComfyUI Node: Generation Resolution From Image

Generation Resolution From Image:

The ImageGenResolutionFromImage node is designed to extract the resolution dimensions from an input image, providing the width and height in pixels. This node is particularly useful for AI artists who need to generate images with specific dimensions that match the input image's resolution. By using this node, you can ensure that the generated images maintain the same aspect ratio and size as the original, which is crucial for tasks that require consistency in image dimensions. The node simplifies the process of obtaining these dimensions, making it easier to set up image generation workflows without manually calculating or inputting the resolution values.

Generation Resolution From Image Input Parameters:

image

The image parameter is the input image from which the resolution dimensions will be extracted. This parameter expects an image in a format that the node can process, typically a numpy array representing the image data. The function of this parameter is to provide the source image whose width and height will be used to determine the output resolution. There are no specific minimum, maximum, or default values for this parameter, as it directly depends on the image you provide.

Generation Resolution From Image Output Parameters:

IMAGE_GEN_WIDTH (INT)

The IMAGE_GEN_WIDTH (INT) output parameter represents the width of the input image in pixels. This value is crucial for setting the width of the generated image to match the original image's dimensions, ensuring consistency in the output.

IMAGE_GEN_HEIGHT (INT)

The IMAGE_GEN_HEIGHT (INT) output parameter represents the height of the input image in pixels. Similar to the width parameter, this value is used to set the height of the generated image, maintaining the original image's aspect ratio and size.

Generation Resolution From Image Usage Tips:

• Ensure that the input image is in a compatible format, such as a numpy array, to avoid processing errors.
• Use this node when you need to generate images that match the resolution of an existing image, ensuring consistency in your artwork.
• Combine this node with other preprocessing nodes to streamline your image generation workflow and maintain control over the output dimensions.

Generation Resolution From Image Common Errors and Solutions:

"Invalid image format"

• Explanation: This error occurs when the input image is not in a format that the node can process.
• Solution: Ensure that the input image is provided as a numpy array or in a compatible format that the node can handle.

"Image data missing"

• Explanation: This error happens when the input image parameter is empty or not provided.
• Solution: Check that you have correctly supplied an image to the image parameter before executing the node.
