ComfyUI Node: 📝 Save/Preview Text

📝 Save/Preview Text:

The Save_Preview Text node is designed to facilitate the temporary saving and previewing of images generated during the AI art creation process. This node is particularly useful for artists who want to quickly visualize and review their work without committing to a permanent save. By leveraging a temporary directory and appending a unique prefix to the filenames, this node ensures that your previews are organized and easily distinguishable. The main goal of this node is to provide a seamless and efficient way to manage and review intermediate outputs, enhancing your workflow and allowing for iterative improvements.

📝 Save/Preview Text Input Parameters:

images

This parameter accepts the images that you want to save and preview. It is a required input and should be of the type IMAGE. The images provided here will be temporarily saved in the specified directory with a unique prefix for easy identification.

prompt

This hidden parameter is used to store the prompt information associated with the images. It is not directly provided by the user but is essential for maintaining metadata consistency.

extra_pnginfo

This hidden parameter is used to store additional PNG information that might be relevant for the images. Like the prompt, it is not directly provided by the user but helps in preserving extra metadata.

📝 Save/Preview Text Output Parameters:

filename

This output parameter provides the filename of the saved preview image. It includes the unique prefix and counter to ensure that each preview is easily identifiable and organized.

subfolder

This output parameter indicates the subfolder within the temporary directory where the preview image is saved. It helps in maintaining a structured and organized file system for your previews.

type

This output parameter specifies the type of the output, which in this case is output. It helps in categorizing the saved files and understanding their purpose within the workflow.

📝 Save/Preview Text Usage Tips:

• Use this node to quickly preview your generated images without cluttering your permanent storage. This is especially useful during the iterative design process.
• Take advantage of the unique prefix appended to filenames to easily track and differentiate between multiple previews.
• Utilize the metadata storage capabilities (prompt and extra_pnginfo) to maintain context and additional information about your previews, which can be helpful for future reference.

📝 Save/Preview Text Common Errors and Solutions:

"Failed to save preview image"
