ComfyUI Node: Image Properties 🧅

Image Properties 🧅:

The NegiTools_ImageProperties node is designed to extract and provide the dimensions of an image, specifically its width and height. This node is particularly useful for AI artists who need to understand the size of their images for various processing tasks. By using this node, you can easily obtain the width and height of any given image, which can be crucial for tasks such as resizing, cropping, or aligning images within a composition. The node operates by analyzing the shape of the input image and returning the relevant dimensions, making it a straightforward and essential tool for managing image properties in your workflow.

Image Properties 🧅 Input Parameters:

image

The image parameter is the only required input for this node. It expects an image file, which the node will analyze to determine its dimensions. The image should be in a format that the node can process, typically a standard image format like JPEG or PNG. This parameter is crucial as it directly influences the output of the node, which are the width and height of the provided image. There are no specific minimum, maximum, or default values for this parameter, as it simply requires a valid image input.

Image Properties 🧅 Output Parameters:

WIDTH

The WIDTH output parameter represents the width of the input image in pixels. This value is derived from the shape of the image and indicates how many pixels wide the image is. Understanding the width of an image is essential for tasks that involve image manipulation, such as resizing or aligning images within a larger composition.

HEIGHT

The HEIGHT output parameter represents the height of the input image in pixels. Similar to the width, this value is obtained from the shape of the image and indicates how many pixels tall the image is. Knowing the height of an image is important for various image processing tasks, ensuring that you can accurately manage and manipulate the image dimensions as needed.

Image Properties 🧅 Usage Tips:

• Ensure that the image you provide as input is in a standard format like JPEG or PNG to avoid compatibility issues.
• Use the width and height outputs to dynamically adjust other image processing parameters, such as resizing or cropping dimensions.
• Combine this node with other image processing nodes to create a workflow that automatically adjusts images based on their dimensions.

Image Properties 🧅 Common Errors and Solutions:

ValueError: Invalid image input

• Explanation: This error occurs when the provided image is not in a valid format or is corrupted.
• Solution: Ensure that the image file is correctly formatted and not corrupted. Try opening the image in a standard image viewer to verify its integrity.

AttributeError: 'NoneType' object has no attribute 'shape'

• Explanation: This error occurs when the input image is not properly loaded, resulting in a None object being passed to the node.
• Solution: Check that the image file path is correct and that the image is accessible. Ensure that the image loading process is functioning correctly before passing the image to the node.
