ComfyUI Node: Load Image (Inspire)

Load Image (Inspire):

The LoadImage __Inspire node is designed to facilitate the loading and processing of images within the InspirePack suite. This node allows you to load an image from a specified directory and convert it into a format suitable for further processing in AI art workflows. It handles image decoding, color space conversion, and normalization, ensuring that the image data is ready for use in subsequent nodes. Additionally, it can generate a mask from the alpha channel if present, which can be useful for tasks requiring transparency information. This node simplifies the image loading process, making it more efficient and user-friendly for AI artists.

Load Image (Inspire) Input Parameters:

image

This parameter allows you to select the image file you wish to load. The available options are dynamically populated from the specified input directory, and you can also upload an image directly. The selected image will be processed and converted into a format suitable for further use in your workflow. This parameter is essential as it determines the source image that will be loaded and processed by the node.

image_data

This parameter accepts a base64-encoded string representing the image data. It is used to decode and load the image directly from the provided string. This can be particularly useful when working with image data that is already in memory or when you need to load an image from a non-file source. The image data should be a valid base64-encoded string to ensure proper decoding and loading.

Load Image (Inspire) Output Parameters:

IMAGE

The IMAGE output is the processed image data in a format suitable for further use in AI art workflows. The image is converted to RGB color space, normalized, and represented as a tensor. This output is essential for feeding the image into subsequent nodes for further processing, such as transformations, enhancements, or analysis.

MASK

The MASK output is a tensor representing the mask generated from the alpha channel of the image, if present. If the image does not have an alpha channel, a default mask of zeros is provided. This mask can be used in workflows that require transparency information or for tasks that involve masking specific parts of the image.

Load Image (Inspire) Usage Tips:

• Ensure that the image file you select is in a supported format (e.g., JPEG, PNG) to avoid loading issues.
• Use the image_data parameter to load images directly from memory or non-file sources, which can be useful for dynamic workflows.
• Leverage the MASK output for tasks that require transparency information, such as compositing or selective processing of image regions.

Load Image (Inspire) Common Errors and Solutions:

Invalid base64-encoded string

• Explanation: The image_data parameter contains an invalid base64-encoded string, which cannot be decoded properly.
• Solution: Ensure that the image_data string is correctly base64-encoded and includes the necessary prefix (e.g., data:image/png;base64,).

Unsupported image format

• Explanation: The selected image file is in an unsupported format, leading to loading issues.
• Solution: Convert the image to a supported format (e.g., JPEG, PNG) and try loading it again.

Missing alpha channel

• Explanation: The image does not have an alpha channel, resulting in a default mask of zeros.
• Solution: If a mask is required, ensure that the image includes an alpha channel or provide a separate mask image.
