ComfyUI Node: ZHHivisionParamsNode

ZHHivisionParamsNode:

The ZHHivisionParamsNode is designed to facilitate the creation of high-quality ID photos by providing a range of customizable parameters. This node allows you to specify various attributes such as size, background color, rendering style, and image quality settings, ensuring that the final output meets specific standards and preferences. By leveraging this node, you can achieve professional-grade ID photos with precise control over the visual and technical aspects, making it an essential tool for AI artists and designers who require consistent and high-quality results.

ZHHivisionParamsNode Input Parameters:

size

This parameter allows you to select the size of the ID photo from a predefined list of options. The size determines the dimensions of the final image, ensuring it meets specific requirements for different use cases. The available sizes are defined in the size_list_ZH dictionary.

bgcolor

This parameter lets you choose the background color of the ID photo. You can select from a list of predefined colors, which are specified in the color_list_ZH dictionary. The background color can significantly impact the overall appearance and suitability of the ID photo for various applications.

render

This parameter specifies the rendering style of the background. You can choose from options such as pure_color, updown_gradient, and center_gradient. Each rendering style offers a different visual effect, allowing you to customize the background to match specific aesthetic preferences or requirements.

kb

This integer parameter sets the image quality in kilobytes (KB). The default value is 300 KB. Adjusting this parameter allows you to control the file size of the final image, which can be important for meeting specific file size constraints or optimizing for storage and transmission.

dpi

This integer parameter defines the dots per inch (DPI) of the image, with a default value of 300 DPI. DPI is a measure of image resolution, and higher values result in higher-quality images. Adjusting this parameter allows you to ensure the final image meets the desired resolution standards for printing or digital use.

ZHHivisionParamsNode Output Parameters:

normal_params

This output parameter returns a dictionary containing the configured parameters for the ID photo. The dictionary includes the selected size, background color, rendering style, image quality (KB), and resolution (DPI). This output is essential for further processing or generating the final ID photo based on the specified settings.

ZHHivisionParamsNode Usage Tips:

• To achieve the best results, carefully select the size and background color to match the specific requirements of the ID photo application.
• Experiment with different rendering styles to find the one that best suits your aesthetic preferences or the guidelines of the ID photo.
• Adjust the kb and dpi parameters to balance between image quality and file size, especially if you need to meet specific file size constraints.

ZHHivisionParamsNode Common Errors and Solutions:

"Invalid size selection"

• Explanation: The selected size is not available in the predefined list.
• Solution: Ensure that you choose a size from the size_list_ZH dictionary.

"Invalid background color selection"

• Explanation: The selected background color is not available in the predefined list.
• Solution: Ensure that you choose a background color from the color_list_ZH dictionary.

"Invalid rendering style"

• Explanation: The selected rendering style is not one of the available options.
• Solution: Choose a rendering style from the available options: pure_color, updown_gradient, or center_gradient.

"File size too large"

• Explanation: The specified kb value results in an image file size that exceeds the acceptable limit.
• Solution: Reduce the kb value to ensure the final image file size meets the required constraints.

"Resolution too low"

• Explanation: The specified dpi value is too low, resulting in poor image quality.
• Solution: Increase the dpi value to ensure the final image meets the desired resolution standards.
